    I got all excited after I got my tranny mount from summit until I bolted it up... turns out my crossmember isn't level so when I went to tighten it up to the crossmember it pulled the metal out of the polyurethane about 3/16's of an inch. Is this supposed to happen? I noticed the stock tranny mount allows for that kind of movement but I didn't think the poly mounts would do that.:confused:

    Little help

    I run an Energy Suspension mount. There was no deflection of the mount wen I tightened it up. Did the metal rip out of the poly part?

    If you have poly tranny mounts you need poly motor mounts as well...

    I'm going too for sure absolutely, but don't even have the motor yet. I'll also have poly body mounts.

    Howdy,

    I pu the poly mounts on both engine and transmission. I didn't get the effect you are talking about. I am running a 4x4 and it uses the two piece mounts that bolt on the top and bottom of the cross member. When I was running the 2WD I also ran poly and I never had the steel more AT ALL in the mount. That seems odd to me...

    The Energy Suspention T mount didn't deform at all on my '91. I also have the poly engine mounts.

    Did you atleast try to push it back in, if thats possible. If it does go back in I would run a washer for a spacer to level them back up when tighted down. Hope it helps.
