Rear axle bushing information

Thanks to Compnine, we do have precise information about rear axle bushings differences between different models,
there seems to be 3 options for stiffness:

Bushing 10150338 (Green)
1990-1994 FE2, FE3, F41 (EX Z04)

Bushing 10150339 (Blue)
1987-1989 All models.
1990-1993 FE7
1994-1996 FE3 (Z04)

Bushing 22597998 (Yellow)
1991-1996 FE1, FE2

After quick searching around, I found that the after-market bushings only have 1 option with the stiffness unknown, I decided to get NOS Blue bushings from Vintage parts.

Notice how the bushing says 'BLUE' on it and also has the same color paint on it.

These bushings can be a bitch to change without proper shop tool. I just drilled the hell out of mine, and used hand saw to cut the outer sleeve to get them out. Took over hour per side.

But it should be worth it. As our rear axles do have quite a side wobble because GM engineers left the Panhard bar away from the suspension, only thing carrying the sideways load are these bushings, witch on my cars are over 20 years old...

Thanks Ryan for re-shipping the Vintage Parts order for me!

Interesting. You may be the only person to ever change these bushings!

I changed mine there really annoying to change.

I just used parts store bushings tho. Didn't feel any difference in side to side sway.

I have some Moogs that I plan to put on. Hell if I would have had this info before I would have got some GM's.
Update please Weba. I can always get the Blues.

Anyone have any info on how any of these compare to the Moog replacements?

I'm gonna have to order from online, no matter what anyway, So I might as well try to get the best.

I will probably buy the softer bushing to keep the car isolated a little.

Koots Moog busings are stiff. The ride is rough, but they handle the turns well.

Weba the update was to see if there was any regrets. Boy did I lose track of this topic.

No regrets. Beretta doesn't really ride like a Rolls Royce in any form, so I'm fine with stiff bushings.
Unless you have like 85/165R14 tires and FE1 suspension.

Also my white car has the nylon bushings and I don't find it disturbing.

Also my ride clunks and clanks as there would not be tomorrow... My guess is something internally torn out in the body.. plus catastrophic engine mounting design...

edit: I'll clarify: I find that swapping in front poly bushings will bring in way more rattles and side-effects than going stiff rear axle bushings for some reason.

I saw that, but this was written 1.5 years ago and wanted to know if anyone else had anymore information since then.

I figured I would inquire about it all in this thread, so as not to start another thread and dilute the information pool, that we all share.

:good:

I will probably end up going with the Moogs, but I might try and find some of the NOS ACDelco bushings too.

I'm not afraid of a stiff ride so much as a rough ride. There are so many dirt/gravel roads here that they can't be avoided. Which is why I want to keep full suspension travel and a stiffened unibody.

Thanks Weba. Yeah having the ultra stiff bushings up front would change the perspective some. I would like to have some blues, but I've had a set of Moogs sitting for a long time. I had Moogs in the front of my 90GT, so I'd say the rear are the same.

Koots get some blues and if you don't like them we can trade(lol).
