Anybody out there?? please help.
Very common BMW problem. The front lateral arms that support the front to rear motion of the wheel. BMW calls it the upper, lower support arm. Two arms connect there. one left to right (think typical lower control arm, and this arm) It has a ball joint that connects to the lower most part of the strut and extends rearward to the rear crossmember and has a large bushing pressed into the arm. You can replace just the bushing if the ball joint end is ok. Bushings are about $45 each and you will need a press.
a 6ya expert can help you resolve that issue over the phone in a minute or two.

Hi. Common problem and one i have seen too many times have a look at your break discs and see if they are warped run your finger around them and see do they feel uneven and if so that's your problem if not you could have a track rod end starting to fail also try your wheel alignment any of theese could be causing the problem.
It sounds like a ball joint is worn, possibly the rack end ball joint or tie rod end. With the bumpy ride it could also be that the front shock absorber has failed. Jack the front wheel up on each side in turn, grab the wheel at each side and shake it back and forth as hard as you can. If you hear or feel looseness, the problem is in the steering, as above. Then shake the wheel while holding it at top and bottom. If you feel looseness then, the problem is in the front suspension wishbones. Repeat this on the other front wheel. Let it down on the ground, then bounce each front corner up and down as hard as you can (you might have to have a second person with you doing this). If you hear a clunk or feel excessive bounciness, it is the shock absorber. When bouncing like this, the car should resist, and not keep bouncing when you let go.
Check engine mounting rubbers or bushes. If worn or loose they can cause noises like this. Shouldn't happen in an 08 though. Check things like the battery strap is tied down and the fuse box cover is secured.
There could be numerous problems going wrong. Your car is rear wheel drive so it could very well be a bad wheel bearing. If it is extremely loose it can cause a shake in your steering wheel. You may want to check on the condition of your tires and rims especially the left front. A bad tire can cause a shake and pull. If you know how to use your car jack you can try jacking the vehicle up, and put both hands on your front wheel and move it manually to see if there is looseness. Most shops only charge about 1/2 hour to shake down the front end. BMW parts are expensive so be prepared!
