When you get it apart and examine the rear bearing, look at the rear case end where the bearing sits.
There is a plastic cup that holds the rear centered in the case --- if it's cracked or damaged the rotor will wobble.
The alt in the 93 should be an 80AMP B-AL157X (from my RPR catalog) 1988 - 93
In my 87 ---- 70AMP B-AL57X ----- that plastic "Tolerance Ring" failed.
TOLERANCE RING 46-91550
