Mein Auto: 1998 BMW 740il
Exclamation Extremely bad shaking on passenger side

Hello people I have a 1998 e38.
So here's the problem: every time the car goes around 60mph the right side front wheel starts shaking really bad. I have to stop the car in order for it to go away. What could it be? We have already change the whole tie rod assembly.
Car has the new 750il wheels don't know of that matters..
HELP!!!!
thanks..

First things first, are the lug bolts tight? If they are then you must have worn or deformed suspension parts over there. Replace all the parts with ball joints -- you did the tie rods, next do control arms and thrust arms. The stabilizer bar has bushings that you can replace, or it could be bent. My two cents, hope it helps.

Yes the lug nuts are tight, first thing we checked.

It happens to me more than I am comfortable admitting.

I assume this was happening since before you replaced the tie rods. Have you had an alignment done? Even if you matched the new tie rod length to the old one, the old one may have been set wrong if the problem existed then. If the problem popped up with the new tie rods, I would definitely suspect alignment.

Wheel balance. Defective tyre - can happen to one straight from the factory. The best shops have a machine that will check side wall flex and tyre pull as well as balance. Wheel alignment not so likely in this case IMO. +1 on checking other components though.
