Toyota Repair: 95 corolla vibration, drive axles, balance wheels

Question
I have a 95 corolla with 92,000 miles on it. It has a very bad
vibration, and the shop I took it to says the motor mounts look
fine, they also said that they read about a similar running condition
from clogged injectors, but they could be sure that was the
problem either. I need to have the timing belt replaced, and the
fluids done, but I don't think it will help vibrations.
Any suggestions?


Answer
It depends on whether the vibration is there when the car is moving or not, vibrations when the car is not moving is caused by bad motor mounts, vibrations when the car is moving could be caused by out of balance wheels or bad drive axles, I don't which is the case but replacing the timing belt won't fix it.
