steering wheel judder/vibrations

[Rich328]

can someone please tell me what could be the cause of this problem!

When im braking in my car, the steering wheel starts juddering/vibrating, I've had the wheels balanced and everything is fine with that.

So i havn't a clue what else could be causing this - its starting to worry me - could it be something expensive which needs doing?

My dad thinks it might be some dirt/stone between the pads and the discs? could this be possible?

thanks

My guess is a warped rotor.
But, I'm new to BMW's.

It could be the control arm bushings or the ball joints (ball joints are part of the control arm).

Does this only happen when you break? if yes then it could be your rotors or even brake pads. Check these two first, if they are fine, then check you ball joint..bushings...etc.
If it shakes even when you are not breaking just driving along, then it could be your tires or rims. If they are fine then for sure get your suspension components checked! Hope this helps....

definetly 100% warped rotors, get zimmerman cross drilled, u can find real ones for not too much

[Rich328]

sorry if i sound dumb...... but what do u mean by 'warped'?

[chungaa1]

warped= (not straight; not linear; etc...)

besides rotors, your alignment could be off.

Untrue.

Steering wheel shaking can be caused by numerous and combinations of things. Mine's starting to shake a bit and I believe it's because of my rotors since they are rather old now, and like my dumbass self, I may have gone to a carwash after driving it for a while one day...

Hot rotors + cold water = WARPING AND CRACKING... BAD BAD BAD!!!

yah mine had been doing the shudder for awhile, it was because of the arizona heat, mixed with washing my car alot, the rotors warped a bit. the pads were worn down and a bit overly dirty as well.

It's this. you have 2 control arms located in your front wheels.

I highly doubt warped rotors

also sumone mentioned misalignment.

dont ever say 100%

im 70 % sure it is control arms and other components of that matter. also alignment.

Try toping off the power steering fuild. I had the same problem, but its goneeeeeeeeee.

OT, but sexy rex... got any more pics?

I have had and still have the same problem, I have changed the tie rod, ball joint, control arm bushings, complete wheels and tyres and balanced, but the problem persists. it does the same thing when I reach speeds between 90- 130km/h.

It feels like the wheels are pulled in alternate directions very fast. definately not the wheels, suspension parts, only the rotor is what I have not heard of before. are these the break discs?

please help anyone.

yes... after a lot of high speed braking, they begin to warp.. making the surface not straight. So when you apply the brakes, the car wiull wobble, because the brake pads are not touching the rotor surface 100% of the time.

If it only happens during braking, then it is the rotors. This was the problem with my car, and i replaced the rotors and it worked perfectly after that.

You could even go and get your rotors re-cut, but i would just get a new set of weither slotted or cross drilled. I would reccomend the ATE powerdiscs. They are cheap and they perform alot better than my old rotors after excessive braking
