Perpendicular to the axle is strange.
I'm with Gloyale in that something other than the lift to be causing this.
If it was the lift it wouldn't be only one side, it wouldn't happen so quickly and unlikely to be perpendicular. The chances of it being lift related and all three of those things happening...statistically laughable. Who else with a lift is having those things happen....? No one?
That said - dropping it may alleviate or mitigate the issue, whatever it is, but I think you'll get that same result if you find the actual issue first.
Seems unlikely but could the wheel or stub shaft have too much play? I'd be prying on the knuckle and trans and looking for movement.
