Default Poly mounts

Horse is dead I'm sure, just need some recommendations for poly mounts. Went to the stealership today and found the front one to be demolished. Which explains the vibration and clunk sound slowing down and taking off.

that's just the upper mount though...

think the OP is talking about the regular, bottom engine/tranny mounts...

and from what I was able to find around online, there's a poly tranny mount that is available, but no one makes poly engine mounts for the bottom... have to just replace with new stockers...

think I need new ones for my car as well...

Yes sir Lew you are correct, should of mentioned that. Good news is the stealership is covering the replacement so it's all good. The mount is completely broken, not worn etc, it's literally discontinuous according to the dealership. I'm a little worried because the clunking sound has been there for a while now and a few weeks back I noticed fluid dripping from the trans pan which is what got my attention. Anyone know how much movement and what parts are likely to suffer, I'm guessing the transaxle has seen a fair amount of vibration..they are willing to examine the transmission and other components, not really sure if they will warranty those if found bad too. Sucks because the trans only has 10k miles on it.

EDIT: They are only replacing the broken one, probably going to swap the top for a poly just because.

This is what mine looked like when I took it out. My wife had been complaining about "clunking" for a few weeks before I had a chance to look at things and find the problem.

I drove it this morning and it still made a little noise when accelerating. I am thinking about replacing the top motor mount to see if that helps.

I have the same clunking noise. How hard is this front mount to replace? Just thinking about doing it now if its easy. or waiting for warmer weather.

I had access to a lift which helped. I attached the repair procedure. We did not remove the exhaust manifolds, but you'll need a very long extension and a swivel-socket or u-joint to get to the two bolts on the top of the mount.

We also didn't have GM engine support stand, and these engines do not have pre-attached lift points. So we VERY carefully used jack stands and some wood blocks on the oil pan while slowly lowering the lift. This gave us enough room to get the mount in and out.

If you can get under the car and remove the giant plastic splash guard take a look to see if the mount is broken. It actually wasn't obvious at first. Without being able to lift the engine a little we missed it the 1st time. Get close with a flashlight and a pry bar. I attached a picture of it out of the car in another post on this thread. Definitely broken.
