i had a similar problem, it might be the stablizer, rubbing against the frame of the car. here is what u do, if it is the stabiler.
get a hose clamp
take off the wheel your having problems with.
inspect the frame of the car. if u notice like a chrome color type of mark, and c the stabiler is close to or touching the frame, pull the stabilizer a lilttle bit it sould be like 1.5 - 2 inchs away from the frame. then put the hose clamp on the stabilizer right by the place it comes out by the frame.
tighten it as much as possible.
that might be the problem.
not sure tho.
Another cause could be the thing that holds the stablizer might be to dry, thats a problem i currently have. im gonna greese the thing up. as soon as it gets a bit warmer outside.
hope this helps.
if it isnt any of these 2 then u might need a new strut.
