Fixing the HUGE Tyre Wear Issue with the Isuzu DMAX, MUX & Mazda BT 50 | SuperPro Steering Knuckles
Вставка
- Опубліковано 23 вер 2023
- The Isuzu D'MAX, MUX and Mazda BT 50 all suffer from a bump steer issue that causes the inside of the front tyres to wear out excessively. Today, we're taking a closer look at how this has impacted my 2022 Isuzu D'MAX over the past 35,000km and installing the new SuperPro Steering Knuckles from@FulcrumSuspensions1976 to fix the issue.

**TYRE WEAR UPDATE**
The rear and the front tyres have now been swapped over for an even baseline to the test - I'll update the below measurements as time goes by:
(Front tyre wear vs km since steering knuckles were installed)
0KM: Outside: 8.5mm / Inside: 8.5mm
5000km: Outside: 8.05mm / Inside: 8.0mm
10000km: Outside: 7.6mm / Inside 7.5mm
15000km: Outside: 7.2mm / Inside 7.2mm
20000km:
any updates on this one?
@@Tilpants Thanks for the reminder mate! I've been keeping a record on the road but hadn't updated here yet - have added 5k + 10k readings now.
@@explorebound thanks for the update. Looks like it's sorted the problem out
Any more updates?
Do you recommend auto king for wheel alignments? Do they know what they are doing
Class action now underway. Register at Chamberlains Law Sydney.
I’ve already got mine booked in. The upper control arms definitely made a difference but still not good enough. I agree with the other comments. Isuzu should be fixing this as a recall
Excellent analysis Daniel, very informative.
Good info. I noticed this on my 2021 Dmax and put it down to needing wheel alignments after GVM upgrade, canopy and bull bar added.
You've answered a lot of questions I've had.
I have a mate with a MUX (he calls it Elon) who wore out his factory tyres in not much over 20,000 kms. Because he was new to 4wd ownership, I thought he'd inadvertently run it in H4 on bitumen for an extended period.
For what it's worth, the Bridgestone AT tyre deal on my stock Ranger gives me a rotate and balance check every 10,000 kms which I've done. At 30,000 kms they're wearing evenly and have plenty of tread left.
Great information, thanks. I think I owe my Mux mate a beer for misjudging him!
Excellent info. Cheers!
lol can’t believe you released this video today
Was literally talking to my mate today about this issue after lift and uca
Interesting to hear that you're still experiencing the issue with aftermarket UCAs 👍
Great vieo as always!
Awesome info thank you very much, as a mechanic havent hurd much bad points to the dmax and bt50
Great info, we get our new MUX in the next week or so. Cheers.
This is an issue that Isuzu Australia should be putting right. Make sure you let the relevant authority (ACCC) know this is occurring. Have you tried getting a remedy from Izuzu?
Pretty hard to nail Isuzu if the vehicle has an aftermarket 2 - 3" lift installed (correct toe setting @ static ride height = toe out every time the front suspension compresses / bump steer) @ 9:30 bang on! A decent wheel aligner is hard to find & should cost you somewhat more than the usual toe n go! WELL worth the money though!
@@mjhmech4903 Thanks for filling me in. I assumed this was happening to unmodified Isuzu's.
I have two Isuzu Dmax Utes, they are both standard, and both of them have that scalloping tyre issue…
I do regular swaps front to back
Yeah it's quite a hot topic on the FB groups with no confirmed solution from Isuzu (although they have recently acknowledged the issue and provided alternative wheel alignment specs to help, but can't say what impact this will have on the tyre wear at this stage). This is happening to stock vehicles too, although I imagine the effects are definitely magnified by suspension lift etc.
@@explorebound
To be honest I didn’t even know that this was a problem with other Dmax owners, I do a lot of towing so I thought that this was only my Dmax issue…
I have one 4x4 and one 4x2, I’ve done approximately 90,000 kilometres on both. I’ve replaced 2 sets (all 4) of tyres on each.
Funny you released this, ive had a lot of wear on the outside of my front 2 tyres (2017 MU-X). I do also think my increase in wheel/tyre size from factory and my 2" lift have contributed to it as i havent yet changed out my upper control arms yet. Just very interesting this is a common issue though regardless.
Interesting to hear your wear is mainly on the outside of the tyres!
Toe-in issue with yours eg incorrect wheel alignment
Would love to follow this up. 21 SX Single Cab. Dealership brought the issue up with me after 15,000km. This is definitely an issue from stock and something has to be done. Dealership tried fixing the issue with wheel alignments every service, which I was still wasn’t overly happy with. By 45,000 they were completely bald.
Thanks for the update. As somebody who went from an ifs dual cab, to an older wagon for solid axles, I'm really wanting an ifs again for the sole reason that newer cars are quieter. On long trips that really makes a big difference, I took for granted things like having a conversation with a passenger or being able to hear music lol. It even sucks on shorter trips tbh aha
I had my eyes on the dmax and didn't know this issue was common, not enough to steer me clear of a dmax but certainly good to be made aware of. I look forward to the update in the future on if the issue has been fixed, cheers
Glad the video helped mate and interesting to hear that you're looking to swap back to ifs! The Dmax is a great car aside from this perticular gripe, but it's hard to find a car without a drawback nowadays I find haha. The main reason I opted for the Dmax was Isuzu's mechanical reputation, above all else I want to be able to rely on my vehicle getting me home when I'm camping somewhere remote. 👍
I love my gu patrol and could pour thousands into the car with sound deadening, speakers etc but my gut tells me I still won't be happy with the end result. As a weekender it's perfect, but as a daily that's when you're forced to re-evaluate your priorities
The only issues I've heard with the dmax besides this is cranks snapping? That might only be happening when people tune them but I'm after reliability too, like you.
Does the new model need ad blue?
I wish there was a petrol dual cab to choose from to avoid the dpf and ad blue situation all together but that's only possible in the American pick ups and they aren't cheap
I think Izuzu trades too much of its reliability reputation on their proper trucks. The D Max and Mux tend to get a free ride and owners tend to get the sort straw when warranty issues arise.
Also missleading advertising comments suggesting the Mux can tow 3500kg. It can only do that if the vehicle has no accessories, luggage or passengers. To late if you paid the money to tow your new 3500kg van only to find the dealer was lying in regard to everyday situations.
@frankguernier2280 in fairness all the manufacturers do this.
@@kitbuilt3845I don’t see anything fair in having to spend thousands of dollars on a vehicle that is nothing but a money pit just to get the ride that should be acceptable from the manufacturer!! WTF we spend tens of thousands of dollars on a vehicle and then have to spend more thousands of dollars getting the vehicle to drive and perform as it should from the manufacturer!! We are so used to accepting all the lame excuses from any manufacturers who will not take responsibility for their errors!! Time to take a stand and not accept their excuses!!
Nice vid mate! Have a set on mine as well (beat to the upload lol) and have had a simlar experience 👍
rubber will wear quicker at start as its softer and starting to harden up alot later n wear will slow down the wear rate basically like driving with concrete tires as they get older but we wear less in the latter stages
well described.
Hay mate
any chance you could give me an update on the tyre wear after the steering knuckles were replaced to date
mine has done 20k km 4 wheel alignment's and front tyres are gone already
thanks keep up the good work
Thanks for this video Dan it was so helpful, I’m going to follow up if the upgrade affects my GVM from Pedders unless you have already checked?
Thanks mate! Regarding the GVM upgrade I wouldn't think it would be impacted by the upgrade, but I'll touch base with Pedders and report back. 🙂
Let’s hope the manufacturers fix this problem
Thanks for the alert - I guess the elephant in the room is how it affects your manufacturer’s warranty? One will hope Isuzu fix this with the next model along with the engine bay body tearing issues.
I bought the ISUZU D-Max X Terrain last year (2023) with a 50mm lift, Fuel Rims and MONSTA Tyres. The front tyres have chewed out in less than 12,000kms. The wear is on the outside edges of the front tyres. The feedback I have had from Gardner Autos in WA was that ISUZU gave the wrong settings to the installer when the wheel alignment was done... I work overseas and am home again in May and organized my car to go in for service and to rectify the faulty alignment. I also want two new front tyres as they are close to outside of road legal. The rear tyres are in excellent condition. Will give some feedback next month... But hey thx for the lead to Autokings in Malaga... That will be a potential if its not fixed properly...
$2,500 well worth it, great improvement.
☝😎
Same as the bt50 ,both Isuzu and Mazda should be paying for all this work for all
If it’s factory fitted no issues
Any word on whether this is the same for 2017 models. A family member has one and inner treads are wearing prematurely. They know little of its previous history though. I’m also considering buying it from them. Happy to do the mod if I’m aware upfront it’s needed.
Was the alignment put back to the Manufactures specs or changed.to fix the problem. Whats the original manufactures setting for the vehicle. Bump steer should wear the tyres 0n both sides of the tyre as the suspension goes up and down.
What is a "specialised wheel alignment" compared to a run of the mill one?
85,000km on my set of AT’s and still going my car must be one the few good ones 3” lift with black hawk UCA’s
Great vid. Subscribed becuase of it
Thanks! 😀
It's a good demonstration of the issue but the testing you did showed toe in, not toe out. Toe in would cause the outside of the tyres to wear prematurely, not the inside. Would have been great to see how some suspension compression altered the geometry (which is obviously what's causing the most issues). Also, I think you mean "minutes" not "seconds" when reviewing the toe angles at about 7:53 .
The bump steer is incredibly evident in car I’ve only done 2000 in new BT50 and it’s like having worn bearings in front. Def factory recall should be.
I had my front tires replaced by Isuzu a couple of weeks ago, they also did a wheel alignment let’s see they go, mine is completely stock
Customer of mine came in with that story. They originally had the settings low because…. Lack of understanding i guess, then he showed me the new specs they set it at and they had jumped to putting it at risk of outside edge wear and fast too…. Seemed like halfway between would have been better
Cost to replace the knuckle?
It's amazing that people pay big money for these Ute's and still they have faults.
Really what are you paying for.
So much to their engineers getting it right and their road test...
Imagine paying big $ for a new DMAX then having to spend another two and a half grand to get it to steer right???
Absurd. Not to mention the money already wasted on the 2 front tyres.
Then everyone walks around muttering the golden line, “you only get what you pay for”.
Ludicrous.
Hi mate. How much did you pay for the steering knuckles? And also what brand it is? Cheers!
Is this problem with all years of MUX or just the latest models?
Hi mate just watch this video very help full but must ask are you running a drif drop and do you run a egr delete cable thanks
Hi mate, glad the video was helpful! No I'm not running a diff drop or an EGR delete cable
Hey Guys. Have had my MUX for a few months now...only 3k driven. Is this an issue shwoing on all Iszuzu or just sone...would you recommend me having someone look into this straight away?? Or do i need some tyre wear evidence ??
Great video. What are some of the cheaper alternatives?
Aftermarket specialised wheel alignments (not following Isuzu's factory specifications) and aftermarket upper control arms can help the issue, just not rectify it entirely. 👍
Munji do over a bolt in kit (offset rack bushes) for only $176
We, at Munji 4x4 Accessories, have been covering this for a long time as well with a few new developments on this issue and all the other issues relating to the rust inside the racks and excessive movement/incorrect adjustment of the rack slides.
There are two much cheaper options we have to fix the bump steer.
Where can buy?
A pedders person told me this week that they are developing a similar product, but it's a ways off being released.
I wheel align a lot of vehicles
And i also pay attention to bump steer assuming load, and these things are so crazy
But look at the angle of the steering arm/trackrod/tie rod/rack end, it points down on an aggressive slope
So as the body lowers it flattens out pushing it toe out
I’ve taken to trying to guess the bump steer when loaded and bumped
But they tend to jump double the toe amount of most other high bad bump steer cars so it’s a moving target
The worst bump steer car is still a certain Suzuki van i saw which ii had to give a wheel alignment problem just to make it straight with two people in it.
Is this a problem on the rg colorado series 2 I have the formula 4x4 lift tit in it scrubbing on inside same tyres as old mate on video
Hi Daniel. If that is a big problem with all of them DMax and MUX. Should that not be a Factory warranty issue ???
I believe people are trying to claim or getting something sorted through the manufacturer, but no luck so far I believe as it probably falls within a technically 'acceptable range' or something along those lines
It’s actually the other way around, the front tyres wear faster than rears, especially on utes where front brakes are discs and rear are drums, generally front does a greater proportion of braking
Not really, I carry constant 800kg of load and the rears wear out twice as fast as the fronts… depends on setup with tray / canopy etc
Very dependant on load and where it's placed, I personally know of guys who are chewing thru rear tyres at 30 - 40k pulling heavy trailers and if your a tradie who is in a hurry you could almost halve that
Thanks for the video, but, knuckle hell, where do you get the income to be able to make so many repairs?
I went through my standard tyres in 18,000km! Front insides were doen to wire. I am in Fiji too, so dealer/Isuzu support is non existent for something like this. An AUS recall would be handy
Its a work car so its not my money being burnt with tyres but its still fu$#ed, see how long these 275/70r18's last 😅
Pretty embarrassing when A-list brand ute has such a fundamental and critical design flaw that has to be fixed by the owner at their expense to enjoy a standard ownership experience. Just to highlight how stupid this is, I am running a GWM cannon with 50mm lift and the same tyres, no rotations after 35,000km and perfectly even wear on all 4. Never had that before in a modified 4WD, glad I didn't pay $20k more to enjoy something like this occurring! I have 9mm wear after the same kms as you on 276/65/18 version of the tyre. Measured in three places across all 4 tyres.
I wouldn't admit owning that but best of luck
Ford FG GT's have this same problem. More so than the std FG's. Probably because they ride lower. And as far as I know nothing can be done. My mechanic told me not to do many 90 degree turns as that is what wears out the inside edge the most. ???
I have a 2021 BT-50, only done 28k km on the stock H/T tyres (planned to change to A/T at first change. They wore to the wire on the weekend when I was in Perth (live in Kalgoorlie), rang the dealership I purchased from to rectify. Mazda claim the bullbar fitted by arb (bought as part of the car) are at fault. Currently arguing for reimbursement for a new set of front tyres from the dealership
Good luck with GC Motors! The weight of the ARB bar particularly with winch fitted actually mask the problem NOT the other way around! Having said that & if we are being honest, the OEM H/T's never last much longer than 30K regardless. (Max I have seen is 45,000km with regular rotation, perfect tyre pressures (vs factory recommendations) etc. This has been the case on BT50/Ranger since 2013 odd (PX) Cheers
@@mjhmech4903 actually purchased the BT from a different dealership (won't name) but had a lot of back and forth arguments with the service manager over who was liable, tried to place on ARB even though my dealings with Mazda. In the end a family connection with the dealership owner had $800 transferred to my account for two new front tyres- just happened to be A/T fitted; in luck that day
Any one know about a steering damper or stabilizer for the Mazda bt50 gen 3?😢
I had no real interest in this information as I own an early model Dmax. But I really wanted to commend you on an excellently presentated video. Thanks Dan and Bianca.
Selling my bt50 in the morning. Dealer blamed me suggesting i was driving around corners too fast.
Mazda went backwards after parting with Ford Ranger IMHO.
Around minute 6.06 your mechanic belted the abs sensor while disconnecting steering arm
I think you need to look again. He was nowhere near it.
Been through 3 sets of front tyres at 32000kms. Pretty bad huh. Isuzu is "managing" the issue now (as of Aug 31st) by setting toe in to +5mm, in order to get more even wear. The dealer replaced my front 2 tyres on warranty and then aligned with new settings.
When I have some money to upgrade suspension, I'll through those knuckles on as well.
As stated by many other owners, 100% should be a recall.
+5mm: Now there's a bandaid solution from Isuzu! 🤔
Does this affect stock configurations as well? Im surprised this doesn't warrant a recall.
Hard for me to say definitively as mines been modified since new, although from what I hear it does affect unmodified vehicles too, just not as badly as a vehicle that's been lifted etc.
I have this problem with my 2022 Dmax too. I've added suspension and maxxis tyres. I've also talked to the fleet manager of a large company that has over 100 Dmax vehicles, all are factory standard. He tells me they are having the same issues, so its not only modified vehicles suffering. I'm looking into starting a class action to have the problem resolved. Please let me know if you would like to be part of it.
I'd say all of us are in mate, remind me when youve started it
@@astingordon-cooke6633 I've been told there is momentum gathering on Facebook. Can't tell you more because I'm one of the three people in Australia that doesn't have Facebook. It looks to be happening though.
My gorgeous chunky Falkens went to an early grave and isuzu has cost me $1000 over it. Not happy Jan!
So you’ve installed a 2-3” lift GVM upgrade (with UCA’s, shocks etc), then had to install a new steering knuckle & another UCA (that’s compatible with the new steering knuckle) to fix it?
No, still running factory UCAs. This issue also affects vehicles with standard suspension so the suspension + gvm upgrade is independant to this.
I have heard BT50 are the same is that true ??
What's the cost off fixing this problem please,my son has the 2022 model,is that affected.
Hi mate! It's $1760 for the parts or $2465 fitted (through Fulcrum Suspensions) Here's some more info: bit.ly/3EXun3T
Hey bro👋🏻 what’s your tyre spec? Are those R17 wheels?
Hey mate, they're 285 70 R17 Maxxis Razr AT811 tyres on 17x9 rims with +12 offset.
I would expect this to be a recall by ISUZU / Mazda, looks like a faulty part from factory, plus compensation for those that have had to replace their tyres early.
Everyone always bags out the other brands saying Dmax and Hilux are the best, they are no different they both have as many issues just like all brands.
Yep, impossible to find a vehicle that doesn't have at least one drawback nowadays I'm afraid. 👍
Do you have a 2022 Dmax ?? We run Yokahama Golander GO16 AT
Yep mines 2022 🙂
I notice ya didnt get Upper Control Arm with this mod? have you now had that installed ??
Still running the factory UCAs at this stage
@@explorebound we are getting package installation 3200$ !! How many ks ya done since fix? Do you just swap tyres left to right or do full tyre rotation every 5000km
What brand was that steering knuckle and where can I get it..
Did you even watch the video? He literally said 'knuckle from Superpro' (@3:10) and mentioned it was sourced/installed by the Fulcrum Suspension group, which owns Superpro.
2015 Dmax have this issue too? still all the same front ends since 2012 model?
No. Only 3rd gen or 2020 on. Yours is 2nd gen. However: If you are smart you will replace the 2 front body mount rubbers for the RG Colorado style & fit a 1st gen or RC Colorado LSD rear diff centre particularly if you do a lot of soft sand / slippery mud driving.
The BT 50 has the same issue.
The cause extra weight on the front end the BULL BAR.
Do all vehicles need this?
This issue is affecting the current model DMAX, MUX and Mazda BT-50. Whether it's worth the investment to fix depends on how many km you plan to drive in the vehicle before upgrading. 👍
Shame on Isuzu for not making a better knuckle from factory . So much for R&D . My Ranger got 90K + out of the factory R/T tyres .
How is the FIX going for the Bump Steer Issue?? we are about to get it done on Our Dmax. only got 15k KM out of a set of Yokahama Geolander GO15 LT tyres at over $430/each!! we have 10mm tread depth on rear and 8mm outer and 4mm Inner on front !!!! just the $3000+ price is a bit of a hit - Fulcrum.
It's going well, after approx 10,000kms the front tyres are now wearing mostly even (see pinned comment for exact measurements).
@@explorebound getting two new front tyres fitted and then bump steer kit fitted.
@@explorebound do you do full tyre rotation every 5000 or just swap left to right?
Neither since I had this kit fitted to the dmax (in the interest of keeping my testing as accurate as possible). So those readings are for the same tyres that we're swapped from rear to front at time of the SuperPro knuckle installation. 👍
Was this sponsored by SuperPro?
This has to be a warranty issue.
I reckon we have not had a vehicle which does not wear the front tyres excessively and, to be truthful, unacceptably, for several decades, until... We currently have a VW Amarok, previous generation, genuine VW. It is now more than 8 years old. It does not chew the front tyres out at all. Additionally, this vehicle is constant 4WD, so there is another "excuse" for dishonest manufacturers to sweep this issue of unacceptable front tyre wear "under the carpet". To me, this vehicle proved that with good design, independent front suspension 4WD vehicles should not have inherent problems with front tyre wear.
I do not understand how manufacturers think they can get away with inferior (poor) design, and simply tell consumers "they all do that". We should be bringing them to account, and make them rectify their poor design.
Mate I had a 1998 Nissan GU Patrol for 23 years and had Bridgestone and Coopers tyres during its lifetime. Never had uneven wear problems. Used to rotate the tyres about every 20,000kms..
Shouldn’t this be done under warranty?
Not much luck with warranty for this unfortunately, I think it's deemed within 'acceptable tolerences' or something similar.
There was a post the other day on the 21+ DMAX/MUX facebook page anout the tyre wear issue then updated with:
"Update.
Can confirm that on August 31st an internal bulletin went out notifying dealerships that the factory specifications for toe in were incorrect.
Previously the specification was 0mm, updated is 5mm.. considering the dealership said my alignment was “waaaay out” when they measured total toe at -3.7mm… then getting an update to say it should really be +5mm"
Edit:
Then seen another post about being able to take your vehicles back to Isuzu to get a free set of tyres and wheel alignmen, unsure how everyone's success will be with such claim but always worth a shot.
Yeah I did see that the other day actually! 🙂 It's my understanding that the new factory alignment specs might have a positive impact (and potentially rectify other issues too) but the bump steer issue will still throw the toe out more than normal on these vehicles - this is essentially how much the front wheels are temporarily pushed out of alignment during compression, so even with the alignment being spot on the change during those moments is the problem if that makes sense?
@@explorebound yeah gotcha, personally I feel this is still manufactoring issue and should be a recall but that's just me 😆
BS bandaid solutions. Next they will be telling you to run 60psi in the fronts!! 😆
How can an established vehicle manufacturer produce a vehicle with such a serious design problem? Ridiculous! So what else have they got wrong? Not fit for purpose, I want my money back! 😡
Why hasn't a class action been filed for this issue? Why should I pay $2,500 to fix this design problem? I am a BT50 owner and I have now chewed though 4 sets of tyres at the front, This includes a set of BF Goodrich. Mazda are trying to blame me because I have upgraded suspension. Which, I installed to counter this problem in the first place before this issue was revealed. I have evidence of wear before mods to the ute, but still no care from Mazda. I don't understand why everyone is letting these guys get away with this?
I feel I have seen this video somewhere else
Appalling. Should be a recall.
Isuzu should fix this under the Warranty 😢.
People need to boycott these cars till they recall it an fix it
I wheel align them an i don’t follow the specs, i follow the how the car reacts to weight an average it out
^* class action maybe 🤔
what you takling about factory tyres man i dom with my 60.000 and they are good ..
Be nice is isuzu could make a car that doesn't have so many small issues that could be fixed for BRAND new ute.
$1700 to fix this issue plus the price of a new car
already spent $1800 on getting the evaporator fixed twice, for a silly manufacture issue as well
This is a factory design fault, My D Max was 12 months out of warranty with 80, 000ks on it. I had nit fixed at NO CHARGE TO ME WHEN I THREATENED TO GO TO. (QCAT). in Qld, Isuzu gave the go ahead to the dealer after a month. Do the same they do not have a leg to stand on. Aproach ISUZU with copies of your invoices and ask for a refund before going to QCAT.
You will get this mate !!
Just put a bracket on the firewall supporting the aluminium pipe with a plastic sleeve to stop electrolysis !

I'll give u 200 for knuckles
I wouldn’t be surprised if you just had a shit alignment in the beginning.. I’ve had heaps of trouble with crap wheel alignments over the years . Crook technicians that haven’t got a clue
