Wheel Wobble (Video)

Im trying to track down a vibration Ive been having. The vibration feels like wheels that are out of balance and the speed of the vibration is consistent with that also. It is not the buzz of the classic driveshaft vibration.

I bought new wheels and tires and the vibration has not gone away.

The vibration is most noticeable at part throttle freeway cruising at around 65mph and seems to improve the faster I go. I took the Chevelle to the drag races recently and I did not notice the vibration at all.

Here is a video of what looks like a slight wobble in the wheels/tires, but Im not sure if this is normal or not? Each side has the same wobble, it is not isolated to one side.

Re: Wheel Wobble (Video)

Universal joint maybe?

That is based on your description not the video.

Re: Wheel Wobble (Video)

I forgot to mention the vibration is felt through the body and floor, not the steering wheel.

Axels could be bent, check run-out. Any noise associated with this?

No noise. What would be the best method to check runout?

Re: Wheel Wobble (Video)

is it noticeable on both sides ? have you tried with wheels off and watching the axle flange see if there is any runout

I ve put a sledge hammer on its nose on ground facing up about 1" from tire and spun it by hand see if there any movement, you can go more elaborite and use dial indicator.

Had to do that on old school bus wheels to get rim even and dead center on the hubs whenever wheels were off

It is the same on both sides. I do have a dial indicator as well.

I had the drums off before to look at the flange and it didnt look as bad. Im beginning to wonder if the drums are not balanced.

If the rims are the same that’s the culprit. I had new Goodyear’s put on my expedition For winter that did that, noticed it as soon as I left and got on the highway, turned around and went back, they spun em on the machine, did their little makeshift dial indicator and saw that they were out of spec. Replaced and all good.

So it's not the tires or wheels fault. Gotta be in your drivetrain, and I would suspect something in your differential / axles.

Re: Wheel Wobble (Video)

I watched the video full screen a few times. The tire seems to have a lot more wobble that the wheel.

x3 it looks to me like there's a defect in the tire. Like the steel belts have shifted. IDK if that's possible, but watch the lines of the tire tread itself in the video. When I loook at the sidewall, I see no wobble, but when I watch the actual tread pattern lines I see that they don't look to be rotating in a straight line.

Did you have the car sitting on those tires in one place for a long time? If not, then have you driven the car over an abrupt speed bump at a faster than normal speed or over a curb? Might your son or wife have driven it and done one of these things to it? It looks like a defective tire to me. Did you over-inflate the tires recently? Just a few wild guesses on my part. But I've never seen a tire tread wander like that while the tire was spinning, as if though the tread is lop-sided while the sidewall appears to be true and straight. Are they dirt cheap tires? Or have you ever run them close to being almost flat for a few miles?

These are essentially brand new Mickey Thompson ET Streets with maybe a couple hundred miles and 1 pass on them. They have not sat for a long period of time.
