My Ride: 330i
my car is sick...

Bought a 2001 330i last week. I have a few questions.
When I am acclerating around 20mph, there is a friction sound and slight vibrating through steering wheel. the car needs an alignment, the steering wheel rests to the right. when i hit the brakes, there is a loud thud and jerk coming from the front right wheel. the replace brake light is on, also the DSC light. finally when i am turning and i hit a small bump there is a loud rattling sound from up front.
Is the friction sound normal? Do i just need new brakes? Alignment? is it all related? HELLLPPPP!

Sounds like you bought yourself a fixer-upper. The thud and jerk can be FCAB'S or bearings. Grab your front wheels and move them forward and back to see if they have any play.

Tried it, doesn't move forward or back, but it does turn from right to left a little.

That clunking noise can be a couple different things such as damaged calipers/ pads, damaged tie rods, damaged ball joints, etc... On one of my personal E46's I had to replace the front lower control arm bushings because they were completely destroyed. The front wheels would jerk back and forth specially while stopping and going.

Even if you don't feel much movement in the lower control arms I would still suggest you replace them with the something like the Rogue Engineering FCAB's



Once you're at it you should replace the worn out rear shock mounts:
