These are the front suspension-to-unibody mounts.
Mine have failed, new ones on the way, I can fix this, but a question:

I have searched my J.33 parts manual and my factory repair guide......should there not be some kind of snubber between the suspension frame (on top) and the unibody to keep all the weight from cantilevering onto these sandwich mounts?
For now, I have slipped some old rubber aftermarket exhaust hanger washers in between (keeps the banging to a minimum), and it seems there SHOULD have been some kind of snubber....I just can't find anything in the "book".

Thanks.
Dave

The guys at SNG says it happens all the time with poor quality sandwich mounts.
So, I ordered good ones!

The back ones have no cracks, pliable, look good.

If the fronts are sheared I would replace all 4--never seen one rip except when they are 40 years old--something is not right--perhaps they were poor quality?

All 4 were replaced by PO.
Rears are fine.
Fronts both sheared.
Snubber would be like a suspension rebound bumper, maybe a bullet shaped rubber piece mounted to the suspension frame and the point against the unibody to keep load off the front mounts.

Dave there are in fact 4 mounts--are you replacing all 4 or just the 2. I am not sure what a snubber is? I can tell you with all 4 mounts in good condition there is no cantilevering as I think you mean. Also I wonder if you do not have a different issue. The mounts are metal-rubber-metal--all of them so they take up the noise.
