FIRE! Replacing Lower Control Arm Bushings: 1993 Lexus SC300
Вставка
- Опубліковано 23 вер 2015
- The worn-out, 20 year old, rubber OEM lower control arm bushings and ball joint boots are replaced with ones made of polyurethane on a 1993 Lexus SC300. (please read additional info below)
Materials:
Polyurethane bushings are made by Prothane Part# 18-207-BL
Polyurethane ball joint boots are made by Energy Suspension Part# 9.13130G
Synthetic Marine Grease is made by Peak
1/4 #28 Grease fittings are made by Powerbuilt (Tap=1/4-28, using 7/32" drill bit)
Important Notes:
1. Before buying new bushings or boots, please check your ball joints for tightness. If your ball joints are bad, it may be better just to go with an entirely new or refurbished LCA.
Note: If you go with an entire LCA replacement, the general consensus states: The LCA's from a 1992-2000 Lexus SC300/400 and a 1993-1998 Toyota Supra are ALL INTERCHANGEABLE.
2. Get an alignment after you do this procedure.
3. The general consensus suggests that the bushings used in this video only fit Lexus SC's 1992-1996 (1997+ model LCA's were redesigned with a thicker, reinforced rear lip which lengthens the barrel thus making the bushing from this kit too short).

I wish you still make SC300 repair videos. Despite the quality, your videos are straightforward and to the point. I'm surprised you were able to apply more grease into the ball joints as many on the forums mention that they're not serviceable.
That thing was blazin! I like how you did that
Nice video! Will have to keep this in mind if I need to do this on my car.
+LamaJ4m24 Thanks brutha.

Great video. Thanks man 👍
for the longest time i thought you have to use a hydraulic press to get the new bushings in, those looked like they went in with ease with just a hammer. i will be replacing my 98 lower front control arm bushings as well now, thanks for the share! I'm subscribing to you now!
Wait! :) If you are installing an OEM bushing, then you have to use a hydraulic press to get them in after you cut or tap the old sleeve out. If you are installing the polyurethane ones like in the video, then no. Thanks for the comments.
+strumpeteer im not doing oem, definitely going polyurethane
Thanks for posting man. Gonna replace the bushings on the SC tomorrow.
great vid
very nice video....well done
+Ron Pop Thanks for the compliment!
Top notch vid
Thank you!
Thanks
enjoyed the video
Thank you!
Thanks great vid!! look easy but when you get the bushing iner sleeve seized on the cam bolt the headache begin lol
+Lexus 93 I feel you brutha. Come down here with us in California where salt, snow, and rain isn't a problem :).
Cut a slot in the sleeve and break it with a chisel? Works for bearings...but they are hardened so idk...definitely a PITA
Thank u
excellent video! couple questions. Did the new ball joint boots come with the bushing kit and I've read that the ball joints themselves can go bad. I realize it costs more to buy new control arms but don't you think it would be safer in the long run? I'm asking because I'm still trying to decide if I'm going to just buy new arms or refurb the ones I have now. I have a '99 Sc300 with 131,000 miles.
+Equalizir Hi Equalizir, the boots and the bushings were purchased separately. The ball joint boots are made by Energy Suspension (bought from eBay) and the Bushings are made by Prothane (bought from a vender on Club Lexus). Safety really isn't the issue unless you continue to drive the car with damaged or bad ball joints (which in my case, were still in great shape). At this time, I didn't think it was worth spending $650+ for a pair of control arms when I'm confident I can get another 100K, only spending under $100 fixing the ones I got (knock on wood). If you don't mind dishing out the cash for new/ refurb ones, go for it if that will give you a better peace of mind. After all, it's a Lexus. ... you gotta spend $$$ to take care of it. BTW, thanks for the compliment!
Thanks for the info! I have a 98 sc that needs bushing replaced, I went to the junk yard n got some lcas from an older sc 92-96. It's possible to put the older lcas with the bushing u mentioned onto my 98 right?
Actually the bushings used in this video are made for the older 92-96 LCAs so your'e good. (The later version LCA's need some modifications for these bushings to fit.)
nice video
+eel1331 Thanks so much.
"It sure is gettin' powerful warm in here!"
Well, I have a beautiful LS400 that pretty much needs all rear bushings done and I'll be damned if I'm going to pay someone to do this. I replaced the entire front end (steering rack too) but it was easier because all bushings are offered in each component so I just replace all components as a whole. No one seems to sell the rear this way.
Quick question though: a ball joint press won't work in removing old bushings?
To answer your question, Yes, the old bushings can be removed with a good press kit (with the right assortments) if you plan to install an OEM replacement bushing. On the other hand, polyurethane aftermarket bushings only require you to remove the rubber portion of the old bushing which means you leave the original outer sleeve intact on the control arm (which is why I used fire ,which allows easy removal of the rubber without damaging the outer sleeve). However, it's better to just replace the entire arm for your LS400, as you did with your steering rack. For us SC300/400 guys, bushing replacement is our only option since aftermarket lower control arms ceases to exist.
@@strumpeteer I appreciate the reply. For whatever reason, every part for the front is readily available for the LS400 but the rear isn't quite as easy. And then there's the knuckle bushings so I'm going to have to tackle some the way you did.
Thanks!
Another great video. Thanks again. You sure know what you're doing. I hope one day I could be as half as good.
I have some light clunking going over bumps and too much bouncing in the front ( 95 SC400 w/ 100000 mi. ) so I checked my suspension out as best as I could - in addition to a leaking strut I saw my lower ball joint on the same side as the leaking strut is very grimy. On the other side, my upper control arm bushings are quite gooey and soft so I assume they're about to fail if they haven't already. My plan is to put on some Tein coilovers (Street Advance Z w/ adjustable damping) ( just for fun ), also ordered the Deizan sway bar bushings kit ( to quell the body roll ), and I'm thinking I may also have to address the control arms with the Deizan control arm bushing kit. It's a daily driver so I hope the Tein + performance sway bushings isn't too agressive but we'll see... I don't mind sacrificing some comfort for a more sporty ride but I'm certainly not planning on tracking or anything. I have another car for that purpose. Do you have any thoughts about my suspension choice ??
I have a question for you, please. In your Important Notes # 1 you mention that it might be wise to buy a new or refurb control arm if the ball joints are not tight. Is there no way to press a new ball joint into the old control arm ? I haven't checked the tightness of mine yet but as I said, one of my lower ball joints is looking very grimy so I assume it has been leaking. The whole control arm is crazy expensive but I'll bite the bullet it I have to.
Thanks for all the super helpful videos. They are an awesome resource.
will this work for 97 sc400? im hearing from others that the bushings are different and i will need to buy a new oem lower control arm. I dont really want to spend $700 per arm.
Sorry, what you heard is correct. The problem is with the lip on the rear portion of the arm that they added for 1997+ models.
I know you made this look pretty easy, but I suck at this kind of stuff... How much would a shop charge me? How many hours do you think it calls for?
Video editing made this job look easy :). The actual job can be tedious work if you don't enjoy this type of thing. I'm guessing 1-2 hours depending on the shop and don't forget cost for an alignment job. The cost per hour and techniques used also varies. Not all places will guarantee anything if you provide your own parts unless you purchase the parts thru them.
What do you mean by align matchmarks?
see 0:38. You paint "match marks" on the cam bolt and the frame so that when you reinstall the arm, you can reposition cam bolt (by realigning the "match marks") to where it originally was. The alignment may still be off, but not as bad as just positioning the cam bolt anywhere. This will give you more time to drive your car without ruining your tires before making it to the alignment shop.
Do you know if that ball joint boot also work on a 1998 control arm
They should fit. The dimensions of the boot are:
Base opening 41.25mm
Stud opening 18.55mm
height 27.75mm
So you can double check.
Strumpeteer I am having a problem with my car tonight, it's making a loud knocking noise and the knocking speeds up the faster I go. When I apply the brakes the knocking stops. What do you think it could be? Could that be a bad wheel bearing?
Maybe. But if it happened all of a sudden, check the tires first, you may have a nail or rock in the treads.
I was able to get it to the shop up the street this morning. Knocking seemed louder, thought it was going to be pretty bad but luckily it was only the brake pad, they said it somehow got loose and was not in the correct spot. It was just a small problem, they didn't even charge me to fix it. Also had them check out parts of suspension, bushings and ball joints etc.. They said everything looked good.
why u need marks?i wanna change crossmember and i wont have a sign...anyway is very important?...have to do alignement...after change struts and crossmemeber
+Ron Pop If you are going to change the struts and crossmember, then marks won't do you any good. Since I only changed out 4 bushings, I can use the marks to get the front wheels close, although not perfect, to being aligned.
+Ron Pop By the way, since your crossmember will be coming out, now will be the time to get that lower oil pan seal replaced.
wont that grease eat up the rubber bushings???? I mean grease pumped later from those grease fittings.
The bushings that were installed in the video are polyurethane, not rubber, and is impervious to petroleum products. Ever since the poly-bushings were installed in 2015, I never had any reason re-grease them. If I ever have to, I will be using a synthetic type of Marine grease. But to answer your question, yes, I've read that petroleum-based grease can destroy or ruin rubber bushings.
Where can I get the lower ball joint boot .site ot part number
Polyurethane ball joint boots are made by Energy Suspension Part# 9.13130G
Hello I have a weird sound coming form my 96 sc300.... can you check out my recewnt video? its a video about the sound it makes and i was wondering if bad control arm bushings cause that. Thank you!!
More input is better than one. View his video here: ua-cam.com/video/O4UOLLNIci8/v-deo.html
that sounds like your wheel bearing and or worn tire
Will this work on my 98 Lexus sc300 the ball joint boot is ripped and I don't want to spend $600 for a set
The bushings used in the video will not work with your 1998 LCAs. I don't know about the boots. If it were me, I'd spend the 5 bucks or so on these boots and give it a shot. ... you don't even have to take the LCA's off the car to do it.
i thought the boots on the sc300/400 where not replacable
There are no OEM replacement boots for these LCA's, hence the reason you heard that. However, the aftermarket polyurethane boots used in the video still holding up after 2 years.
whats the difference between your bushings on a 1992-1996 through 1997-2000
1997+ model LCA's were redesigned with a thicker, reinforced rear sleeve lip. This makes the opening too small and overall length too long to fit the bushing from this kit used in the video. If you're handy, you can cut the lip off like a few have, but do this at your own risk.
strumpeteer so the ones I see are 7.0 cm long how much would I half to cut u think and the with is 5.1cm and the long sleeve is 6.6cm long and with is 3.0cm what do think
Sorry, I wouldn't know without seeing it. You will just have to install and see for yourself.
What's the part number for it
Energy Suspension Part# 9.13130G
you will need to reuse that rubber stopper at 1:40, if there is a gap in the front bushing area when you place the control arm back in. if there is a gap the control arm will move causing the bushing you installed to tear.
There was no space to reuse that rubber spacer with the urethane bushings I used. Without them it was a tight fit! I guess ymmv. Thanks for the info.
Nice video...subscribe.
