Money money :o) Wicked wheel shudder..
 
A week a go i had my wheels road forced balanced and they insisted that I had a bad tire and it needed replacing. Well I had it replaced.

Now my car shudders from 62-80mph

I had an indy replace my drive belt tensioner, Oil filter housing gasket, and mecatronic seal and they also replaced my tranny fluid.

Now my issue is I asked him to check my wheel bearings and he said they are fine. So now I am at a lose whats causing the shudder. It can be seen in the wheel too it moves left to right.
I am beginging to think i should just replace my rotors. They dont feel warped but what else could it be at this point.

Do you say when the car's jacked up the wheel's loose - moves left/right? Talkin' about the tire rims.

Or the steering wheel shimmys at speed?

If depending on a vendor to fix, you should see a front end specialist or BMW Dealer.

I have had my wheel alignment done, tires road forced balanced that highlighted a issue with a tire replaced it same thing is happening. had my bearings checked. I have zero abnormal wear on the tires they are all wearing well within exceptable wear rate (16k on the current tires with zero inside wall wear).

The steering wheel at speed shakes left to right about 3mm - 5mm travel.

Did you have the wheel shudder before the force balancing? If not, why are you throwing other parts at the problem if it did not exist before the wheel was balanced/new tire?

Rotors would only cause a shudder while braking.

Look for worn suspension arm bushings/ball joints. Easily checked for and easily fixed.

Don't forget to check sway bar mounts while you're there.

At what speed does this occur? Mild balancing prob might show up ~75 mph.

What do you mean when you say you can see it in the wheel?

See Post #5, above.

I think it is possible the new tire is bad. Went/is out of round or the like. Check that first.

Leekay07 09-28-2012 01:54 PM

OK so since my nwq tire where put on i have had this issue. The tech noted when the tires where installed that a rim was bent. So I always put it down to the rim. I just replaced the rim and had the road forced balance done and they waid one tire is bad and that the shudder is a result. SO I got the tire replaced under warranty and well its still here :( from 55-80mph. I had the bushes checked the control arms checked the sway bar bushes all good.

If you had the tire/wheel assembly checked on a Hunter "road force" 9700/9712, this machine should have been able to diagnose the problem. The machine, however, needs periodic software upgrades...calibration, and is only as good as the skill of the operator....and then they have to apply the "correcting" weights properly.

Sounds like someone doesn't know how to use the machine if they gave a "pass" to the second, replacement tire IMO.

Do you remember how many "pounds force" the first and 2nd tire had before and "after" alleged correction? Did they find any contribution of the wheel to the problem? This machine (if indeed the Hunter machine) can easily detect out-of-round wheels.
