I am going to try to replace my rear differential carrier to chassis bushings. Anyone have experience with replacing these. Also I was advised to avoid the poly type bushings. Not sure why and have only seen poly type replacements for sale.

Hi g,
Paragon Reproductions shows the rubber differential carrier bushings in their catalogue. #5976

I am a big fan of poly bushings but I shied away from using them last spring for motor mounts when I pulled the L-82 for a rebuild and have had a poly differential carrier bushing sitting in my garage for years now since any engine mount/transmission mount that are poly will transmit more vibration than rubber. I would go rubber.

If you mean the front snubber bushing, the poly versions are not made correctly (too large). Use rubber.

If you mean the two cross member bushings, there's a 99.9% chance they don't need changing. I've yet to see one that's worn out.

The poly bushings have no give to them and can rip the bracket loose from the crossmember.

The correct bushing kit with rubber cushions and bolts can be found here:

Replacement instructions can be found here:

If you are talking about the end bushings on the crossmember you can find those at this link

If you are working on the crossmember bushings, once the cross member is out of the car we use a press to remove and install the bushings. If you need more help with that just post again.

Thanks for the reply and the diagram. Thats just what I needed. Doesn't look too bad to replace. Funny most of the corvette parts guys are selling poly but a lot of folks say they are too large. I'll stick with rubber.

Any idea what the torque is when replacing these bushings?

Try 55 - 75 ft-lbs

Mike Ward

It's specified in the instructions Wilcox posted. (?)

greggome

No its not specified in instructions>

Snubber Cushion torques at 55-75 ft lbs.

Rear outer cushions torque at: 55-65 ft lbs.

speedreed8

yeah it is..... second page #2 with triangle.... 55-75 ft lbs.
i just did this, got the kit from Willcox... the large washer in the kit is a little wimpy, wont stand the torque without bending. i used the oem large washer.

greggome

Yep. Sorry missed that 2nd page print.

Thanks for the advice about large washer.
