Common motor/trans mounts that go bad

Post by archaicguy »

I know that I need a new mount (I have the jumpiness going into drive or reverse) but I haven't had the time to see exactly which one or ones. What are the usual ones to go bad and how much of a PIA are they to replace. I'd like to know before I start pricing parts.
Thanks guys

The front one is the only one that goes bad typically. If its been bad for long enough it can put extra stress on the rear mount, but the main problem is the front trans mount. I've never seen a side mount go bad, they are just a pivot point.

Replace your junk original mount with this: http://www.pontiacbonnevilleclub.com/fo ... 44765.html
