Should I replace the mounts? or would it be ok to keep driving it the way it is... its not doing any damage (I dont think) its just annoying when I stop at a light and the steering wheel shakes.
Replace the mounts. It is already doing damage that you don't know about yet.
If it is that bad (steering wheel is shaking),
1. The tranny is probably sitting on the subframe,
2. The CV joints/front axles are probably affected
3. The Steering wheel/column is already affected.
The condition of the car cannot get better without taking care of this issue. It will only get worse with more damage as time goes by.
