The wobble should be minimal. The rear bearing sits in a nylon bushing.
The rebuilds often use a cheap bushing that will wear or creep out in
time causing the bewaring to come loose. The rotor will hit the stator
coil and may cause some damage. The alternator may also whine from the
rotor being miss-aligned. If you have 1/4" of play, it should be
repaired to avoid a sudden failure.

Subject: Alternator wobble?

Hello,

In all the time I've had my van the alternators ALL had some wobble in
the
shaft, even the rebuilt one I got had a littttttle wobble. The one in my
van
right now has like...maybe 1/4" wobble in the back bearing, it runs
fine,
with the belt tightened up. Is this a common thing with the atlernators
or
did I just get a weird rebuild! If it is WACK, then WHO makes a rebuild
that
won't develop wobble and where can I get it!
