My friends car shakes violently when coming down from a higher speed to 50MPH. It also does it a little but when accelerating, but not nearly as much. His car is a E34 525i. It only does it at 50, and then the rest of the time its fine. Any idea what this may be? Thanks

My car did this when I bought it, and it turned out being the thrust arm bushings... could also be the ball joint at the other and of the same arm.

... and now a couple of years later my car seems to be getting the 'shakes' too.... reason being is that mine were not tightened under load.... so when tightening the new ones make sure the car is put on the ground and then tightened.

Never thought about that, its coming from the front wheels as the entire car, and steering wheel shake violently. But we're rather confused because it only happens right around 50MPH, and mostly when decelerating, when accelerating it happens, but very very small. i will check the wheels, but if it were to be that stuff I would think it would happen at other speeds.

I just noticed i messed my first post up. It only happens at 50mph, no other time.

if a wheel was loose, you would hear it bangin' at all speeds...

it's most likely thrust arm bushings and/or ball joints...

i'll get the symptoms on video tomorrow (as i got the same thing and i know it's the thrust arms going south again) so you can see if they match up.

probably as torque suggested...... however, had a similar experience after putting my spare on the front of my E30, rode fine till I got on the highway; 50mph + and the car went nuts... turned around, went back home..... took a close look at the wheel and couldn't believe I hadn't noticed before, but the rim was all bent to sh*t...

so, if the wheels have recently been replaced, taken off-put back on, etc... the wheel itself could be the prob.....
.... if this prob came up at random, or just started gradually, torque's prob is most likely your prob.

Thanks guys. I'll pass the info on to my friend. It just started happening randomly, so I guess its the thrust arm stuff, but we'll check the wheels first

i had the same problem (95 540i). just replaced the thrust arms and the problem
is solved. if u do the work yourself it will be cheaper to just change the bushings,
however if your'e paying a mechanic you might as well change the whole arm.
the reason being, by the time u pay your mech. to cut out the old bushing and press in the new one - u can have a new arm complete with a new ball joint.
i replaced mine both left and right for $200 plus $150 for labor.
check eurowebparts.com
also i used the arms from the 750i(beefier)

If it isn't the thrust arm is could be an wheel that isn't properly balanced. This could be fixed by simply balancing your wheels.

My 94 530i shakes like a son of a gun right now at 50MPH ever since I had my summer rims and tires installed, I'm getting my tires balanced next Friday.
