    Hi, I have an 01 chevy 1500HD 4x4. I just rotated the wheels yesturday. It developed a steering wheel shake at low speeds and a vibration in the steering wheel at higher 50mph + speeds. So far i have jacked up both sides and spun the tires by hand. I didnt see a noticable wooo in them. I rechecked all the lug nuts and they seem to be seated properly and center. nuts are torqued to 140 lbs.

    What else could it be? I've been told a wheel bearing may be ging bad, ive been told a tire might not be balanced but that doesnt explain low speed shake in the wheel. Anyone have any input? Thanks

    it could be a number of things i had a truck that did that an guess what is was a slight bend in the rim . it could be a broken belt in the tire , a bad ball joint, a tie rod end that needs replacing , etc check that front end out real well. if ya need any help let me know thanks,,george

    Gm had a service bulletin for a steering shaft issue! Maybe take the truck to the dealer and get it fixed for free!

    Sounds like a split cord in a tire as George said, Especially if it started when you rotated the tires. I had this happen and It was hard to see the tire was not perfectly round, When I rotated them to the back the steering wheel quit shaking but I had a vibration on the rear. New tires was in order for mine.

    Well if you didnt have a problem before you rotated the tires, its obvious that the tire or rims are to blame.

    If you used an impact wrench, you may have warped a hub also, Im thinking that I torgue mine to 100 pounds and never had a problem.

    I originally torque them to 110 pounds with a regular 1/2" torque wrench but i looked up on the automotive service program we have at school and it says 140 lbs for the HD's so i then torqued them to that. only used the impact to take the nuts off. I have a feeling it is a broken cord in one of the front tires. will rotate them to the back tommorow and see.
