Besides the ENGINE mounts, where else are there MOUNTS that could go bad?

 

Three on the differential and one on the transmission. Two on the engine. The front mount on the differential has a tendencey to go bad.

 

Thanks hailers, if the front mount on the diff goes bad, what happens usually?...what sort of symptoms.

 

The front of the differential will rise up and strike the body. Notice that the driveshaft is attached to the front of the differential, and just imagine what harm is being done to the u-joint on the driveshaft(u-joints are not replaceable on factory driveshaft so you have to buy another driveshaft$$$$$$$$$). You'll also get a thump when stopping. Its a son of a gun to replace. Not just remove two nuts and put a new one on type thing. There is a description of how to done last December somewhere. Rates right up there with doing work under the dash, just harder.Oh yes, the thing cost 80-125 bucks.
So a straight answer to your question about what happens, is, you get poorer, your voice rises in anger and curse words, and you lose the better part of a saturday replacing it.

 

It makes very loud cluncking noises every time to accl qucik, or decell qucikly...

I know... mines broken

Alot of people replace the mount with a piece of angle iron instead of the mounts to keep form replacing it every 2 months.

 

also 2 subframe mounts

most common breaking are the pass. side motor mount and front diff mount.

 

Yeah...what Scott said. My passenger side motor mount was broken and I replaced the "y block" transmission mounts (2 of them). My selector lever would move around alot when on rough roads...now it does not move at all.

When I launch my car @ 4000rpm, it get a constant banging in the back. I thought that was from the shocks or something, but I guess this could be the diff hitting the undercarriage? So the mount could be bad?

 

ROSH7 YEP. It could be tearing up your driveshaft ujoint also. Dyre gave a good description.
just having fun.....you also have three mounts for your fuel filter. All of mine are broken.
