Re: How do you know when your body mounts are bad?

Some of the mounts were like old rubber bands left in the sun, not only deflated, but stuck to the steel inserts like glue.

And it does make a noticeable difference to the amount of rattling. Was not as bad to replace as I expected, except for the one near the rear tire where the captive bolt was 1/2 rusted through. Replacing that was a little more work.
Did you use the poly mounts or the stock style mounts?
