i put the motor and trans mounts in and had some vibration. it gradualy got better as i drove it.

**Johns00Z28** · 10-09-2008, 04:44 PM

I hear it's a real pain in the ass to swap the motor mounts....is it really worthwhile? My y-pipe bangs and I'd like to fix the problem which is why I'm asking.

I drilled out the the rivets and installed the the poly's into the clamshell that took me 2 hours.I had a shop put them on it took them almost 3 hours.

i have poly motor and trans mounts... there is very little shake... if you guys think this is bad don't ever cam your car...

**Crimson Sin** · 10-10-2008, 07:58 AM

I have a small cam. The shake at idle is NOTHING like the earth ending vibration I got at WOT in third with the poly trans mount. Knocked my freaking coffee cup out of the secondary holder by the glove box..
I happen to like the shake at idle. Having my kidneys re-aligned at 80 mph, not so much.

sounds like it wasn't installed right then or else your motor mounts were shot... mine hardly vibrates at all...

I heard that the trans mount makes it more likely to snap your trans tail shaft

i doubt it...

**DIRTY JERZY** · 10-10-2008, 09:46 AM

Oh I probably should have said that was on cars that kept the stock motor mounts

**Pete Rock98** · 10-10-2008, 10:22 AM

I'm running mid 10's on the stock 130k miles motor and tranny mounts. I have a set of poly mounts sitting in the garage (I've had them for 6+ months).
