Rear Suspension Knuckle Bushing - 4 Ways to Remove/Replace - Chevy Venture AWD
HTML-код
- Опубликовано: 5 авг 2024
- Some valuable tips we learned for removing and replacing rear suspension knuckle bushings, which can be a challenge to press out and back in. Loose bushings can result in uneven tire wear due to poor alignment. These techniques can be used with knuckle bushings on any vehicle.
Many thanks to Al for helping with this project, and having many of the tools we needed.
This particular van is a 2002 Chevy Venture, AWD. The same bushing also fits Chevrolet Uplander; Pontiac Montana & Aztec; Buick Rendezvous & Terraza; Olds Silhouette; Saturn Relay; and Cadillac Allante, DeVille, Eldorado & Seville.
The methods I show are:
1. Using a Ball Joint Press Tool, which you can rent often for free at auto parts stores;
2. Putting a bolt through the middle of the bushing - the key is having spacers the right size to push the bushing out from one side, while pressing on the knuckle from the other side. You'll need a fine thread grade 8 bolt about 1/2" x 6" depending on your bushing and spacers. An air impact wrench is recommended if you have one. Heating up the knuckle with 2 torches can also help.
3. Cut the bushing from the inside with a reciprocating saw or hacksaw. This works best if you can drive the center piece out first, otherwise you have to cut through it too. Stop right at the knuckle, and then press or drive out the pieces.
4. Remove the entire knuckle and have a machine shop press out the old bushing and press in a new one.
To install the new bushing, you can often hammer it in with the installation tool, which is simply a ring the right diameter to press the bushing in. It may help to put the bushing in the freezer or a bucket of ice for an hour first. You could also press it in with either method 1 or 2, but might need different diameter spacers to press in than out.
You may need 2 jacks, one for the vehicle, and one for the knuckle, and may need to remove the brake caliper, rotor and parking brake cable. Hang the caliper aside with an S wire so as not to stress the brake line.
We installed Moog K200840 bushings, but found the new ones were a few thousandths of an inch bigger than the old ones, so had to sand out the knuckle to get them to fit. You might want to go with OEM parts.

Excellent camera work and explanation
Dude your video is amazing I went and bought a kit for $229 @ advance auto it couldn't do the job. I had to use the old school technique you posted. I am an old school mechanic and I get the job done the old school way. Anyone watching your video or reading my comment always try the old school way before buying expensive tools peace.
Thanks for the video. On a 2005 Buick Rendezvous the inside bushing was loose on my knuckle bushing so I used a saw's all with a carbon metal blade and made 2 cuts and the out side of the bushing came out easy. I honed the inside and greased where the new one was going in, used heat, hammer, ball joint press and got it done. Before this fix, the dealer wanted $900 per side. Thanks again for the video.
It's surprising how hard those bushings can be to get out and back in. Glad to hear the saws-all method worked!
This video was very helpful. I wish I would have considered this earlier. Instructional videos are great to show me how to replace something. But, of course, with the job I had, there were several "Oh sh*t" moments. I was working on a bushing in the rear of my Mercury Mountaineer. Different configuration, but similar concepts. I already have a ball joint press tool. So that was helpful, sort of. I suspect the bushing was very old. The press tool pressed out the center of the old bushing, but the outer metal sleeve remained in the knuckle. Just great, lol. I did not have a torch, went to the store for that. That didn't help. I found your video and went back to the store for another torch and bolt hardware to try that center press idea. However, that stupid sleeve did not budge. I found a reciprocating saw with a metal cutting blade. There was enough clearance in the wheel well so I sawed away. Sure enough the sleeve came free and I was was able to get that out. However, now the brand new bushing is only pressed half way into the knuckle. I highly suspect there is blockage from rust and other build up inside the knuckle. So I had to order a set of sanding drums. Once those arrive later this week, I press out that bushing and do some sanding like you did. I am optimistic that will help. Thanks for sharing this!
Glad the saw worked for you. In our case the replacement part I bought online was not exactly the size of the original equipment, though it was supposed to be, but in the middle of a job at a friends house I wasn't going chasing down hard to find parts, we just made it work. This can be one of the more challenging projects many DIY mechanics take on.
This was a huge help with my 05 AWD Montana. I had to take off the hub, in order to get room to use my drum puller and I also had to grind a little to get the new one in.
That was VERY THOROUGH & helpful Thanks !!!
very thorough explanation and demo
....nice job, your technique is ingenious... thank you!
Great video man. Lots of explanation and options for getting that sucker out!
Thanks I learned some good pointers
Very helpful video!thanks for the great tips
You're welcome!
excellent video!! thanks!!
Good Job common design,works all.
thanks for the video its the same problem with my 2007 rendezous
Thank you very much for this video. It was very informative and while I didn't need the whole video because I'm very mechanically inclined when I came to actually getting the bushing out this high quality video help me know exactly where to pry to get it to pop out.
Nice video, clearly explained. It's important to have the suspension loaded (as you did) before tightening the bolts. Otherwise when you lower the car, it'll put a twist in the rubber part of the bush. Just a note for anyone who jacks up the vehicle under the frame etc.
EXCELLENT VIDEO
Thanks!
THANKS*
Thanks for the video 👍
Thx
hahahah im so glad i watched this.....im not going to do it now ....Im off to the experts
It can be a real bear. I'm glad I had a mechanic friend with better tools than me, and lots of muscle.
Hi! I was wondering if a stainless steel adapter would be strong enough to press out a bushing and than press it back in?
Very helpfull, especially the tip to freeze the bushing before installation. Just one Q, if one bushing goes, then is it necessary to change the other side as well..? Thank you.
Most likely if one bushing is worn the other side is too, or soon to follow. While you've got the tools out, and since you'll need an alignment afterwards, it's generally wise to do them both.
Thanks for this. Very helpful. I had a question about how much torque that impact you’re using is rated at
I don't know, it was at a friend's house, his tool, pretty old, but did the job.
Great video! One question, do you have to remove the rubber seal in order to push it in with the tool moog supplies?
No, as I recall, the rubber seal doesn't get in the way at all, not sure if it's even removable. You want to be pressing against the outside metal.
Does the flange go into the knuckle? Or does it stay outside the knuckle as a stop?
This flange goes inside the knuckle. We saw the flange on the new part. Had to look carefully at the old bushing in the knuckle to see where it was. I'm not sure if that's true on all vehicles.
Ford recommended replacing knuckle now i know why.. 2012 ford explorer xlt the replacement bushing doesnt fit! How long do i have to sand? Should i start with a metal file or something? Whats the best lube to use? Does freezing it overnight help?? Someone PLEASE HELP!!!
It depends on how much too big it is. Can you get one from a different maker that fits better? I sanded on ours for about 1/2 hour - the important thing is to sand evenly all around, and check every now and then to see how close it is. I think a sander takes it down faster than a file, but you could alternate. Freezing does help, probably for an hour is enough, and add heat to the outside part. I wish I had sanded the first one longer, as it was really hard to get in. I don't think we used any lubrication - graphite might be good for that.
You can alwasy put the new bush in the freezer overnight then heat the arm give you a smidge more room.
My mechanic said, the knuckel bushing need to be replaced with other parts cost 900 dollars
Yes, that's probably about average for suspension work. That's why some of us do it ourselves. I replaced the 2 rear knuckle bushings plus the 2 front control arms and 2 wheel bearings and the total for parts was about $300, but it took us 2 days to do it. We probably saved over $1000.
Hartz Homestead nice！hope I'm as handy as you guys.
I felt sorry for the mechanics that dealt with this when these repairs were all to common
Yes, it takes a lot of muscle and leverage, took 2 of us most of a day to do both sides.
Hartz Homestead bless y’all’s heart, I’m gonna have to tackle this job really soon, and it’s going to the be horrible since the bushings are completely destroyed
...the Dealer/Stealership mechanics have All the tools they need to do this job, in under an hour. Time is Money for a dealership.
