I installed all three new motor mounts on my 1979 300SD W116, the engine did not line up very well while putting in new front mounts, prying the engine was necessary. The rear mount was a snap, however, I had to pry the bell housing from the cross member to get it to avoid vibration while underway, going in reverse up hill was very loud. The engine/transmission is settling back on the cross member. Any ideas?
The chassis has about 340k miles on it and the engine was rebuilt about 85k miles ago by the previous owner. I can say that the rubber under the car is warn.
Thank you.
