Hi all,
My car(Nissan Sentra GXE 99) recently ran over a rock which internally damaged quite a bit of front right side. The sway bar,rack & pinion, and bearing were all replaced. However, when I drive around 40 miles/hr a humming noise (it like a cyclic noise,i.e. comes and and goes rhythmically) starts to come from the front right hand side. I took it to my mechanic who replaced all the parts, and he said it might be because of the faulty bearing, so he again replaced the bearing and put up a new one. However, the noise is still coming. My mechanic pretty much checked everything but couldn't figure out why that is happening. I showed it to 3-4 other mechanics which say the same thing that it sounds like a bearing noise, but it is not because of the new bearing i have put. Wondering, if anybody on the forum has any idea as to what might be causing it?

Thanks!

if the bearing was not tighten to specs, then it could have play and making some noise. did it damage the tire? is it a new tire? have your tired changing the tires from the from to the back or so?

Tires are brand new(Yokohoma Tires). and the front one was not damaged but the rear one was. I haven't yet tried rotating the tires.

rotate the tire first, after that i suspect the CV jionts, one may have been damage (daughter once broke the inner CV joint, control arm, wheel etc etc)
