E32 Vibration While Moving - BMW Forum

rb26 · 04-09-2005, 12:32 AM

When i get my 93 740 iL, up to about 90mph, my whole interior starts to vibrate, i took it to the dealer, but they were not able to fix it completely, they balanced the wheels. It isn't as strong as it used to be, but it still is vibrating, but it is only the steering wheel. what could be the problem, is it the tires that i got on it, they are 245 40 18. I bought it with these rims that have the bmw logo on it but the dealer said that the they were knock offs, also there isn't much room between the tires and the coils, but there aren't any marks on it. What could be wrong with it?

Thank you in advance for your thoughts

what brand of tires do you have? it could be the road force of the ties causing this. and although i would expect the vibration to happen at lower speeds, do you have centering rings for your wheels since they are not BMW wheels. if the wheel has any slop on the hub with all the lug bolts out that can casue a problem. and i don't wanna come off as an ass but why do you really need to drive at 90-100MPH anyway.

they're Nexen tires that i bought for 105 a piece new at a local tire shop, and there are centering rings. There doesn't seem to be any slop on any of them.
The reason i have to drive that fast is because i'm running late for school almost everyday.

hm not to knock your purchase or anything but i've never herd of that brand of tires. you might want to take the car somewhere that can measure your road force on the tires. usually for car tires the road force shouldn't be much higher than 13Kg. if the road force can't me matched with the wheels to get it low enough to, you prolly don't wanna hear it but Michilin has great tires as far as road force goes.

Yeah i know the tires are cheap, but in california, there are a lot of tire shops that claim to know what they're doing, but sometimes their work is questionable, along with the products they sell. I got these tires for 105 a piece, while Pirelli and Michelin both were over 170 a piece.

Yo. I dont think its your tires. I have an e32 750il, and my steering wheel vibrates also...My wheels are completely balanced as of friday, and i have pirelli's with factory rims so it cant be the tires/wheels.

Hi @ all

I guess its the Tires, BUT if not...

Check you Pitmun and Idle arm. Check the Ball joints and controll arms. Maybe evenj the swaybar-link.

You said the car was at the dealer....they should have seen if its one of the above listed problems, but u never know.....

bye

I'd put $10 that it's the control arms....BMW has never had a great design for them....

Yeah that, I've heard bmw mechanic gossip about how those are the first to go.

Did anyone sugjest a drive shaft?

Angelic0- · 07-13-2005, 01:38 AM

drive-shaft hook-up or whatever it's called

control ends....

could be this...

but i'd take it to a BMW dealer, and make them sort it out, there's no price for safety

The most common high speed vibration issue is the Upper Control Arm (Thrust)Bushings, they just do not last. On my 1988 750 they were good for about 70,000 miles. If this is your issue, then there are urethane bushings available and depending on mileage a new control arm with bushing might be the way to go.
