Can't find the previous threads, but I seem to remember it was the inner cv joint of the axle. Replaced it quite some time ago and then "more recently" it started shaking again. I say "more recently" because I don't drive much (ride my fixie to work)....I also replaced the front mount that was bad. So what gives?

 

Get your wheels balanced and see if that helps....

 

shake on accelleration is most often a bad cv joint, the inner ones iirc

You may have replaced one side of the car, but there are 2 axles~
did you replace 1 bearing or the entire axle assembly, new is better than rebuilt ~100$
LA roads not cv's best friend
even brand new parts can fail or year old

Get it on a lift for inspection, alignment shops should help you out

 

ck the other mounts--once front goes,, the pass side follows
