Fingers crossed this is the problem. I hope to be able to get to it in a couple of weeks.



I checked my front wheels for movement with truck up on stands and there is a slight amount of movement, but nothing that would be likely to cause the vibration I've been getting. Still hoping it's not a wheel bearing.

Wheel bearing is like $35. Once you have the right tool it's not difficult to change.

Do the process I described earlier to check the bearing. (and will repeat here).

When I just replaced my bearing I noticed no slop in the bearing/hub until I loosened the axle nut. Once that was loose and I tapped the axle in a few mm so the axle wasn't clamping the bearing tight holy crap was the bearing sloppy. I could twist it off axis with one hand from just the hub over a degree. I wish I took a video.

When I pressed in the new bearing and the hub into that, I could barely detect any off axis motion whatsoever. Also after getting it all back together I noticed my steering wheel is now more centered when driving straight indicating that almost certainly the bearing was twisting while driving and when braking occasionally would wobble like a bad shopping cart wheel.

I haven't speed tested yet to confirm if the braking shimmy has also been cured but the wishbone arms looked in perfect condition when I was doing the axle/bearing/brake job this week
