Front Right Wabble over 70 mph

[mathetas]

I just recently purchased my '98 323is. It really is a beautiful car that has been well maintained. It looks like a brand new car.

Anyway, I was travelling back to school yesterday, and upon switching lanes on the interstate, I noticed the front right wheel (or area) producing a major vibration cruising at 75 mph. Even though I'd had the car a few days, I hadn't noticed the vibration. After further testing, I figured out why I hadn't noticed the vibration. It only occurs at speeds over 70 mph. I had not been driving on the highway, and when I test drove the car, I didn't take it over 60 mph.

More specifically, the problem seems to be more pronounced when I veer or turn to the left. However, when I turn to the right and then stabilize straight, the vibration will also usually occur. When the problem occurs, it is almost as if someone mysteriously changes the road surface to that grading that wakes up sleeping drivers - without the dramatic noise. In a way, it sort of made me think my wheel was loose.

Anyway, I'm lost here b/c I've never owned a BMW. I don't know how Germans make their suspension so keen yet. Please help...

Worn tie rod (tie rod end)?
Bad spot in tire?
Bent elevator assembly?
Bent wheel?
Out of balance wheel?

Thanks in advance for bumps...

I'd say have your wheels blanaced. Sounds like you threw a weight to me.

Also, it could be your balljoints. Mine are going crappy, and I get a slight vibration, but it's more pronounced while braking.

Ok, so it could be like one of a thousand things, but have your wheels balanced and get an allignment. If that doesn't fix it, then we'll start tossing out the other ideas.

Loose / worn / damaged wheel bearing?

Put the little guy on a frame lift... After spinning each tire, I noticed that they all wabbled a bit. Especially the front right one. They have developed flat spots in them from sitting so long without being driven. So, guess it's buying some new tires for me... Thanks for all the response.
