Weird noise / vibration from front right wheel...HELP!
First of all, I know this has been addressed elsewhere, but not of the resolutions/thoughts seem to match my issue...sorry for the new thread!
Background: I bought my 04 330Ci a few months ago and soon after noticed a "chirping" coming from the front left wheel. When i jacked it up, I noticed that when spinning the wheel, it won't make it all the way around freely (Seems like the pad is slowing it down in one spot...thought it was a warped rotor). The same thing applies to the front right wheel. I bought some new/better pads for the front and put some "Brake Quiet" on the back of them and the chirp disappeared - but it's still making contact every time the wheel turns.
Now, I'm noticing - every time I drive - a rhythmical "whump whump" coming from the front right that increases/decreases with speed. When sitting in the passenger seat you can feel it beneath your feet. I replaced the tires/fixed the air pressure and switched the rims around (to test) and I don't think it's a bent rim or bad tire. As I said the pads are fairly new...and I just replaced the rotors with Brembos, even after noticing the old ones weren't warped. Finally, while the rotors were off I inspected the bearings and couldn't find any problems. They spin freely as they should with no noise and there's no play in the wheel when it's bolted on. The calipers don't seem to be stuck, as they depress easily when I take a C clamp to them. I'm stumped!
Non related (maybe), it seems like I have a new leak in my clutch master cylinder.
Has anyone experienced these symptoms and/or does anyone have a clue what might be wrong? Had the dealer visually check out the popular control arm and other suspension components and couldn't find any problems.
