Ford F150 One Piece Driveshaft Slip Bump- FIX!

[@stevenharrell2273]

I can’t say thank you enough. I’ve had my truck for 10 years and it has “bumped” from day one. Everyone just said, “Yeah. All F150s do that!” Well....not anymore. My 2005 F150 XLT drives smooth as can be now. I would have sworn that the rear differential was shot...but nope. An $18 kit, and about an hour of my time was all it took. THANK YOU!

[@timmaysmitty]

Holy Shit! I finally know what's wrong with my truck! I've been dealing with it for years now. I tried googling when it first started, but found nothing. Man, thank you SOOOOOO much.

[@GETLITUP69]

You better be the highest paid Ford Tech in the country!!! Your a Legend!!!! Props to you! I greased my shaft and its fixed!

Years ago,auto companies had a grease zerk on the driveshaft where they should have them now . This probably saved them a 5 cents or less per unit . I hope they were happy with their new found gold mine because it surely has caused the consumer a lot of headache. All this lubed for life stuff is stupid..

[@Hamchuck112]

Thank you for taking the time to make this. I bought a 2010 FX2 with the 2-piece driveshaft and 67,000 miles. About 3 weeks later I started experiencing the super annoying clunk whenever I accelerated and stopped. I thought it was the transmission at first shifting hard but then realized the RPMs didn't change when it clunked. Got the shaft repair kit you mentioned on eBay for $17 and man what a difference. Took me 45 minutes and the truck drives smooth as butter now. A huge relief knowing that's all it was.

[@jorgeandresvelez5479]

For months MONTHS no mechanic could figure out what that annoying ass bump was. They all said the same thing "it's a common ford issue" until I saw this and tried it myself. I must say...you're the man! I'm in love all over again

[@derrickaverett9062]

I just viewed your video and I decided it's the best thing for me to do is to try to correct that problem myself instead of going to a mechanic I have a little mechanical skills but I have never dealt with the Driveline I'm going to give it a shot and see what happens thanks I'll get back in touch

Thank you for this video... I went to a mechanic that estimated in $800.00 to fix the noise, he said it was the deferential... another mechanic said he had a pick-up truck with the same problem, he sold the truck because he could't find the problem... I saw this video, I've done the same and my pick-up truck now is fixed, it is like miracle... Just grease, I spend only $10.00 .

[@BondsCreekKnives]

8 years later after making this video, it is still helping people. I had it in my head there was too much slop in the transfer case or the trans mount was bad. Mine was clunking hard. I had just replaced the driveshaft not long ago and just couldnt imagine that could be a problem. Sure enough the splines were dry as hell and greasing it completely fixed the clunking. Thank you.

[@s.o.f.fpatriotsforlife414]

Your wording is impeccable bumps that aren't there or shifts, I couldn't of thought of a better way to explain it myself well done

[@slow5oh89]

This worked on my 2016 FX4 SuperCab with one piece driveshaft. Noticed this issue when I bought my truck used in August 2023 and was racking my brain trying to figure it out. I thought it just had play in the ring and pinion until finding this videos. Thank you for posting this. So, to those with newer trucks this issue continues to be a problem and this solution continues to fix it. I just used some blue grease I already had in my grease gun. Feels like a new truck now. Thanks again!

[@CS_Concepts.]

Had this exact issue on a 2013 f150. Went to ford and picked up a tube of the grease you linked in your bio. Put it in this morning and the issue is gone. You’re a life saver dude! 🙏 People we bought from told us they were quoted 3-4000 to fix the noise

[@dustinholmes7525]

Yessss! I could not figure this out for the longest time. It was really bothering me. Put it up on the lifttoday at work, pulled off the drive shaft, greased the splines, and no more binding when pulling off from a complete stop! It feels good. Thanks for this video!!!

[@user-hy4sq4ok3l]

Thank you so much for this video. I took my 2014 F-150 to a shop and they told me I needed a new rear end, would cost between $1800-$2500. Watched your video this morning stopped by Auto Zone and $12 later I have no bumbling when I start and stop. Thank you again.

Your video was extremely helpful. I replaced the bolts with new as a precaution for $10.
I read that others had issues with chocking the rear wheels. I used 4x4 pieces of wood and plastic RV chocks to secure the wheels.
Thanks for making this video, you’re the absolute best.

[@mculli80]

I have a 2010 with the two piece drive shaft that had this problem and you aren't exaggerating one bit on how horrible and annoying this problem is. It made me hate and want to get rid of my truck. My local dealer fixed it using the method you showed under warranty and the drivetrain feels nice and tight now. I'm back to loving my F-150. Thanks for posting this. I know this problem has been going around the forums for years.

[@FordTechMakuloco]

On the two piece one yes but not many talk about the 1 piece drive shafts.

[@mculli80]

Chad Fraser I can't speak for everyone, but it's been over a year now since the dealer fixed mine using this method and my driveline still feels nice and tight, good as new. I'm not sure why people are telling you to wait for your U-joints to fail. Is this a common failure on our year truck (2010)?

I'm having this issue again on my 2006 F150. In 2016 it started so I took it in to a ford dealer. Paid $351 for the repair. I recently started noticing that thump again. Thanks for the video.

[@StrangerInAStrange]

Thanks Brian. I seem to be experiencing the 'bump' in my 2017 F150 with the one-piece drive shaft. Really started noticing it after dropping the rear differential cover and changing fluid. Wondered what the heck I could have done!? Now, it seems it may be 'what did Ford do?'. 🤨 I'll be pulling this soon and greasing it up.
Update: Got my 12-Point 12mm socket, Blue Thread Locker and Blue PTFE lube today. Lubed my shaft, went for a drive . . . no more 'Slip Bump'. Thanks again!

[@milesfifer171]

I noticed it looked like thread lock on the rear drive shaft bolts, is that what you used the blue thread lock on?

2005 F150 Super Crew Lariat with the one piece steel drive shaft. This started happening to me, and the truck stranded me in the middle of a busy intersection. The drive shaft broke in half! Had to drive it home in 4x4/front wheel drive. Make sure to keep these yokes greased with the PTFE/Teflon grease! Got mine back on the road after jumping threw a few hoops finding a good driveshaft.

[@MrOlderandwiser]

GM had this same issue years ago. I did hundreds of them. Same thing....they had us grease the slip joint as a band-aid, and that didn't fix it, in the long run. Replacing the slip yoke with the heavy nickel plated yoke did fix it.

[@artramirez3506]

Thanks for this helpful video. Did this procedure to my 18 2.7 Scab yesterday and the 2 piece drive shaft looked a bit different. The splined section that came out of the rubber boot was like a foot and a half long with wide splines. It did have some grease but I added quite a bit more. It helped somewhat with strange clunks when slowing to stop.

[@blakefindlay1870]

2021 and they still haven't properly fixed this. 36,000km on my 3.5 eco and taking it in in two days to have this fixed. Took the service manager out for a test drive with it to show him and he confirmed that's most definitely the issue.

Thanks man I couldn’t figure out the source of my clunks and this solved it, may end up replacing the slip yoke in the future if it acts up soon

[@tsc3576]

Also, if reusing the old driveshaft you need to take a file & file off burrs @ the start of the spline @ the front of the insert where driveshaft spline first slides in. This is what causes it to try to grab/stick. Then grease as shown & re-install/re-stab driveshaft.

I was amazed to.lesrn about the dry spline "thud" Had emptied my bed, checked ujoints and.transmission mount Bout ready to start disassembly front to back

[@SnakeRiverFishing]

ptfe is slick stuff but if anyone wants to set it and forget it awhile, use full synthetic marine wheel bearing grease, stalube blue is the best

[@FordTechMakuloco]

Is it good at ultra low temps like -20 though

[@SnakeRiverFishing]

FordTechMakuloco It's all i use for most everything and i live on a mountaintop by the canadian border see -20 actual temps regular during the winters here. ptfe is great in engines and fast spinning bearings / bushings etc that build up heat friction this is a simple joint that only needs to be free to slide a small bit nothing is spinning past anything. I have a 1996 F 250 HD diesel 4x4 that has that lovely dipped in blue crap at the factory that has so many problems down the road mine froze solid had to torch and pound it off and was concerned how thick it was. The joint only needs to not have excessive slop and basically lubed anything will work I use marine wheel bearing grease because it stays where you put it and will not allow water to enter the joint, on my truck it's a 2 piece so that joint is out in the open not the back of the case but it's the same great video ill probably watch some more been a ford truck owner mechanic by necessity since 1973 and my first rig was a 67.

[@phayes4031]

Jedi Yeah, Tundras are notorious for axle seal leaks dude. Every car has its faults. Ford for the win

[@klc317]

I had something similar on my '03 4x4 Ranger. It also has a one piece aluminum driveshaft....got the good ford tube of the same grease and it's been good for several years now. I originally thought it was a u-joint but ended up being this exact same issue.

[@jackjetpilot]

"Internet gold" - works for my 2021 as well. I had the same "clunk".

[@Ed-ty1kr]

This goes back, way back into the laste 90's. I have an 02, F150 long bed with 320k miles that is set up with this aluminum one piece drive shaft. Buying a new drive shaft is a $350 pricetag, but simply greasing it is what I do from time to time. And if its a bit worn that just gives a place for the grease to be without drying out too quickly as you tend to push most of the grease out with that chroming new and a super tight fit. Chroming or not, its a darn spline joint... grease it.

[@surg9029]

My 2011 raptor had the driveshaft replaced to fix this problem but it only worked for a couple years. Adding the grease fixed it for about 6 months before it started sticking again. I’ve seen fixes where the shaft was drilled for a grease fitting to make it easier to add grease without removing the driveshaft. Removing the driveshaft without a lift in your garage is a pain.

[@hawaiianf1504]

Brian, I have a 2009 F150 4.6L 6r80 trans with the two piece drive shaft but both ends are Flanged so there's no slip joint going into the Trans tail housing. Am thinking that since there's a flex boot at the carrier bearing that's the spot i need to add the new grease. Sound right to you?
Because of your really great videos and the way you walk thru us through the repairs I had the confidence to tackle all of the upkeep repairs on my truck. Thanks Huge for all you do!! Really awesome.
So far, after re-watching your repair videos to get my head on straight. With my son's help we have managed to replace all of my shocks/struts, transmission oil/filter and new adapter, spark plugs and coil packs.
Little bit stuck on the drive shaft upkeep (bump and stick issue - big issue for me) and need a tad bit of your wisdom. I bought the white Teflon repair kit that you showed in this video. Because i wasn't 100% about the driveshaft I didn't take it apart when i did the other repairs. Realize this repair is a no-brainer for you but i am like i mentioned a tad concerned and really do want this bump issue fixed right.
I do have an extended warranty on the truck but it expires this year and have only used it to replace the windshield when i bought the truck new. It had bubbles in the glass from the Kansas plant.
Please help here -- Should i warranty the driveshaft to fix the bumping issue on my '09 pickup w/about 50K miles. It's not drastic mind you, but really freakin annoying. Thinking about the poor plating FOMOCO found and you mentioned. Am I right about where the spline is (at the carrier bearing) ? I'm kinda comfortable doing it but it's hard the son's gone back to the mainland and I'm handicapped. It would most likely be an all day task for me. Don't quite bend like when i was younger.
Can i get from you the TSB or Recall numbers to show the dealership for the driveshaft for my truck? Do you want my VIN # ? The dealership isn't the most friendly at giving out info and acknowledging there's a repair TSB Recall out there. They tried to make me pay $150 to grease the wheel bump stops. Who knew that i needed to a dab of grease there every so often. It's listed in the repair books or service warranty.
Questions - Am I right about where the spline is (at the carrier bearing) ? Can i get from you the TSB or Recall numbers to show the dealership for the driveshaft for my truck? Do you want my VIN # ?

it actually happens in older ford's all the 90s probably until then but it's not nearly as bad because of the added knuckles in two piece shafts... I can't remember a truck growing up my father not putting a zerk fitting in by the spines. driving a truck that didn't have grease all in the splines was like pulling up to a red light soon as you came to a stop it feel like someone lightly banged your bumper with a fist .👊🏾and when u take off a light 👊🏾 only ocd people probably even know what I'm talking about 🤣

Dang, wish I would have seen this earlier. My 2016 did the slip bump at stop signs too. Most notably when it was a rolling stop or very quick 1 sec stop. I searched all over for this issue and could never find the fix. Dealer didn't have any solutions either. I got so fed up with it, and the supercab door rattle that I ended up trading it in for a 2018 supercrew. If I could have fixed this I probably could deal with just having the door rattle.

[@jdgarwood66]

Bungee cords or 550 cord is great for fixing ujoints....you dont need to drop the drive line....just tie it up.

[@digger105337]

My 09 had this. My impression was a hard downshift or once I looked back to see if someone tapped me in the back when I stopped. Since it is slipped into the transfer case having lube oil in it , why does it even need lube? This doesn't say much for the lubrication properties of the thin trans fluid thats now used vs the old gear lube models.

[@leonardgilbreath9004]

My 06 F150 has the same bump when taking off at a stop and this explains what's happening.

The biggest problem is Ford does not doing any testing done and releases the vehicle way too early.I don't even torque down the 4 driveshaft bolts down using the German torque spec using an impact.

Did Ford ever start greasing these? I'm chasing a loud clunking on my 2020 F150..it primarily shows up on bumpy dirt roads. I thought it was worn out leaf spring pads but now I'm not so sure. Would dielectric grease suffice if I end up having to grease the splines?

Do you also have to insert the yoke into the transmission in the same orientation or just line up the flange bolts? Thanks!

Ive got the same bump on my 2007 sporttrac limited with the 4.6 setup.

This problem isn't new to me. I wish I'd heard about it before. It drove me insane for 15 yrs in a 1995 jeep Cherokee and later the same problem followed me on 1999 E 150. Shops and dealers didn't have a clue. I'm an industrial tech. I learn things daily and so do they, in sure. I corrected this issue purely by accident. It was until I watched this video that came to realize. . I had learned to ignore it.

Thank you!!!

My 1994 has done this since I’ve owned it I’ve gotten so used to it it doesn’t even bother me, and yes the u joints have been replaced and the driveshaft was marked before removal

I have a 2013 one piece driveshaft. Replaced the driveshaft, u joints, and slip yoke and greased splines with ptfe grease. Still have the slip bump even at 60mph. Did i just not use enough grease?

I got a good deal on my Excursion because of that and then it went away right after I bought it, but I learned about it a year later and that was 10 years ago.
