RE: Wheel Wobble
Had a similar experience after a brake job.  Very competent shop BUT the
employee that did the work wasn't paying attention.  Had a loose axle nut on
the right rear.  Into the shop a second time before we caught it, obvious
after putting the van on the rack and grabbing the wheel.  If the people
doing the brake work thought they had to remove the axle nuts they could
have loosened them and not torqued them back to the right spec which is very
high.  But I'd expect to get a bunch of bearing noise in that case along
with any wobble.
