Hi guys, I hope someone can help me out with this-I'm at wits end!
I have a 97 SC400 in which I recently installed an engine that I re-built. The engine runs great, but the drive-line has a vibration at several points of road speed, 20-30, 55-70, and others.
It is felt mainly through the floor/seats, not the steering wheel, and is independent of engine rpm (I put it in neutral briefly while at road speed and the vibration remains, while rpm drops).
I have replaced :
Transmission mount-only slight improvement,
d.s. with a used one-no difference,
I even bought a one-piece steel driveshaft with aluminum adapter discs-little to no difference.($$
$$)
I am thinking of trying to replace the front and rear differential carrier bushings, but am having a hard time finding the parts. This is a street car, so I don't want solid bushings.
Am I on the right track? Is there anything I'm overlooking? I'm leery of throwing more money at this without being more certain as to the problem.
Any help and insight would be appreciated.
Regards,
M.R.
