my 06 e55 sometimes the steering wheel wobbles from 45 to 60 mph and some times it does not. Can anyone get what is it from, could it be the bushings or wrapped rotors?

i have brand new tires on there and rims are straight.

thanks

 

thrust bearings?

 

if its doing it only at certain speeds = resonant vibration, then its probably a balance issue

vibration only at certain speeds is usually a balance or tire issue

and toadster- we dont have "thrust bearings" ... you might be thinking Thrust arm bushings

 

thanks guys!

 

See if your wheels are bent.

 

He already said his wheels are straight.


OP- Did they do an alignment and balance with the new tires?

 

anytime the steering wheel vibrates above 55 mph the problem is coming from the rear tires.

 

Are you running stock wheels?

 

Those are the most flamboyant stock wheels I've ever seen!

 

those are not it... he has the other first set on asantis

 

Say wha?

 

It's probably very likely it is not hub centric. You may need hub rings. If it is for sure a wheel that is built specific for Benz and is in fact hub centric the only other thing I can think would be that you need to road force the tires. The tires can still be in balance and "zero" out but what happens is one area of the tire can have too much material essentially and cause a heavy spot which while spinning would cause a vibration. What they will do is match that high spot on your tire with a low spot on the wheel. In most cases vibrations are caused by 3 or 4 things: bent wheel, out of balance, custom wheels not hub centric, road force the tires.

 

Really?? Any car? If so thank you for sharing the knowledge!!!!

 

yes sir
next time you are at a tire shop ask them and they will say the same thing

 

Well then the shaking in my fathers w140 is from the rear accumulators. Thanks! This forum has paid dividends today

 

, i swapped back to the asanti's 20" with new tire

 

new rear tires too Shardul

 

usually when its the HUB it will make a noise. So there is no noise coming from the HUB

 

Were they road force balanced?

 

the vibrating could be that the car's got so much power that it wants to take off nigg aight..... girl

 

what exactly is road force balanced? never heard of it. Is it something different than the regular balance that shops do or something special
