Bad Vibrations! Need Help!

96SNAKE · 12-13-2000, 05:32 PM

My car has a problem where the aluminum driveshaft is rubbing in the driveshaft tunnel on hard acceleration in first and second gears. I haven't changed anything on my suspension for two years before this happened. It is lowered with Eibachs but not extreme at all.

-To try to cure this, I have added these parts to the car with no cure of the driveshaft problem- KYB shocks,struts and quads and FR upper rear contol arms.

I've noticed what appears to be a crack in the passenger side motor mount but its hard to tell. Could that be the problem? I'm reluctant to believe that it is..

I'm at a loss here guys.. any ideas??

Check the motor mounts and tranny mounts. When I was a kid with a new 78 F-150 with a barely streetable 460, I had to go to solid motor mounts due to the high torque numbers she was putting out. I got the same thing you did.

I keep hearing about how crappy the Eibach spings are too but I don't see any sagging going on. The tranny mount looks ok too. I guess I'll try to replace the motor mounts but I just don't want to keep spending $ without actually fixing the problem. The thing that sucks with a problem like this is you can't just look at it and see the problem so you sort of have to experiment.
