So I put on the front 350z revised suspension and now when I hit a bump the front end and steering wheel shakes and rattles. Everything has been installed correctly and all nuts and bolts are as tight as they can get. Are the struts bad or is there some other problem?

 

Did you get an alignment? Toe is probably out of spec, and so is your alignment. As for rattles, depends where they are coming from. Also "as tight as they can get" is not good approach, they need to tightened to spec, not to the most tight you can do.

 

The rattle coincides with the shaking so I believe it is the suspension making the noise. My real concern is the shaking. No I didn't have the alignment done. You are supposed to wait until the springs settle.

 

I'm also thinking it's alignment related... Not sure what would cause the front end to really shake/rattle otherwise.

 

The front of the car seemed a bit bouncy today when driving in to work so that makes me think the struts are bad. The guy I bought them from swears there is only 27,000 miles on them but I'm not so sure.
