Rubber Sub-frame bushings
 

I'm going to have my transmission done around the end of the month and would like to have them replaced too.

Where can I get them and what should I expect to pay?

Thanks,

Ed

I have researched this lately. through gmpartsdirect it came out to about $8 a piece. you need 12 pieces not counting bolts and washers. I found out I didn't need bolts or washers. I had one bad bushing. I am going to replace all of them. the total works out to $110 or so for all 12. alot more through the dealer. expect a long wait, nobody stocks them.

I've had pretty good luck with parts at the dealership by me I think I'll go in and price out the bushings for the hell of it. GMPD charges an arm and a leg for Shipping and Handling on everything.

Travis do you happen to know the size and thread pitch of those bolts?

I just replaced some of them on my 93. My dealer stocks all of the parts for these. Keep in mind to grease the rubber. I had to pull mine all back apart cause the new rubber was creaking so badly on my floor. I got this trick from a local body shop that said to grease everything. It worked excellent. ;)

My local dealer appears to give me wholesale friend price. I knew mine weren't stellar..but seeing one again last night reminded me how "not" stellar they were. A dealer I will go..a dealer I will go..lol

better use correct grease...
 

...or you will rot the rubber very quickly. But I suppose if you have to replace these bushings, then chances are the car is well over half worn out so even greased the car will be long gone before the rubber melts away. Keep in mind that they were not greased when the car was built, so why would they creak now? Everything needs to be fresh under there to keep it from making noise... and installed properly. Mike

Damn I wish I would have thought of this before I had my subframe dropped during my build up! I'm sure they could have used it :(

Glad to see you're thinking ahead!

Re: better use correct grease...
 

Theres only one way to install them basically, and I have no idea why the new rubber makes all the noise but it did on my car. I have just recently expierenced it after replacing the mounts and rubber. It is all brand new and was just the fresh rubber rubbing against the metal tightly. I got the greasing trick from a local body shop so they must have had the same problem. ;)
