I would be guessing right now considering what you have done and the info we have. Here are some guesses:

Trans mount

engine mounts

driveshaft clamping nut

trailing arm bushings / worn front suspension / tie rods

Flex disk nuts / bolts

Wheel bearings


5hit, buddy... anything that moves.

However, you can make a really good guess at whats going on by driving certain ways. When you are on the highway, focus on the characteristics of the engine and road speed.

Make it shake, then immediately lay off the pedal... what happens? RPMs change by about 500 or so, but the driveline rpm will remain mostly the same.

Try to determine if the load on the driveshaft from the engine has an effect also.


Next step would be to start prying on suspension parts and find the culprit.
