I recently replaced my axles on my 99 si about 5 days ago, but when i accelerate the car still shakes and vibrates alot, like if they were still bad, but without any noise or chattering coming from the axles. i took my wheels off and inspected everything and there are no rips in the boots or any kind of grease leaking. the car shakes really bad if you accelerate hard. i think it may be bad engine mount bushings or something because it does not feel right. what do you guys think the problem is??
thanks.

have you checked the tie rod ends? and all other front end parts i.e. ball joints, bushings

What axles did you put on the car? I'm 99.94% sure at least one of those axles has a bad inner joint. Back in 2004 I had 3 consecutive sets of axles that had bad inner joints straight out of the box.

Get under the car and grab the inner joint cup in one hand and the axle shaft in the other, and try to twist back and forth in opposite directions. There should be ZERO free play. Even the slightest amount will cause nasty vibrations during acceleration.

no i havent done any of that yet, but i am going to look at those. i just bought cheap replacement axles from autozone, but at least it has a lifetime warranty. but im going to check that out as soon as rain clears. thanks for feedback.

AZ axles are junk! something else to think about is bad motor/trans mounts
