Wobble at 65mph +

[oldsrider87]

Replaced front passenger side wheel hub/bearing assembly the other day and now it seems to have a wobble at speeds 65 and up, i have had to replace this part on other pontiac's that i have owned so i know how to do it but i double checked everything to be sure and could only find that the caliper has quite a bit of play. Anyone have any issues like this, any ideas how to stop the wobble?

I'd have your tires balanced and rotated and see if the vibration moves with it. I'd also check and grease the caliper slide pins, make sure they're in good shape yet, as well as check to make sure all the fasteners are tight, including your lug nuts.

What direction does the caliper have play in? Towards the face of the rotor along the slides, or along the circumference of the rotor, in and out from the center of the axle?

Along the slides which is normal for these cars i've heard. I double checked everything, hope i didnt get a bad bearing/hub assembly they are easy to change but its freakin cold here and my cutlass is in the garage for the winter!

The caliper play sounds normal. There should be some play with the brake pedal relaxed.

Is there play back and forth on the wheel pushing on either the 12 and 6 o'clock positions or 9 and 3 (with the wheel in the air)? That could indicate a bad bearing, or even a bad ball-joint or tie-rod end.

No play while in the air , the car never had the issue untill i replaced the bearing, im thinking maybe i got a bad hub assembly but not sure. The car was drove for about a day and a half with bearing grinding a bit. The wobble is more like a shimmy in the front i cant feel it in the steering at all.

I will say this, in the past I had a pretty bad shake when braking at 65 or better, which was a combination of warped front rotors and a bad hub. Just replacing the hub fixed it about 90%.

Not sure if this helps, other than a bad hub could cause the wobble. It might make sense to lift the car and see if the wheel seems to have play when you push / pull on opposite ends. I'd be surprised to see a bad part out of the box, but I guess you never know.
