Front end wobble/shake.. Any ideas????

99 Tahoe LT 4x4 4dr

I've got a shake in my front end and steering wheel at around 32mph up roughly 40mph. It's a little hard to explain, but it pretty much feels like a broken belt in a tire or loose lug nuts (That's just an example of how the shake feels). I do have a little play in my pitman arm, but not much. My ball joints, wheel bearings, and tie rod ends are all tight. I had my tires rotated and balanced to see if that was the cause, but no change. I had someone tell me it could be warped rotors, but only 25% of the time does the shake get worse when im braking. Is there a common thing that causes this shake? Or any other ideas of what would be causing this?

Check for a bad half shaft....

If there is some play in the pitman arm, I would replace it..... probably along with the idler....

I agree with lester replace whats worn and check half shafts if problem persist

definately not rotors. they would only shake only when you apply the brakes. would definately replace anything with play because you should anyway. maybe test drive after each thing replaced to figure out what it actualy is so you know next time.

Kinda sounds like what mine is doing, I havent rotated the tires yet.... I have a new Pitman/Idler/Bracket......
