Wheel Wobbles while driving
Owners of 2011-12 Buick Regals may encouters a situation where the Wheel Wobbles while driving during the 1-2 shift. This occurs at speeds from 1-2MPH, up to 20-mph. It may occur more often when turning right while accelerating.
GM has redesigned the half shafts to correct the problems.
The new part numbers are:
LH Front Wheel Drive Shaft #22870110
RH Front Wheel Drive Shaft #22870111
To break in the new shafts, GM recommends accelerating from a stop with wide open throttle through the 1-2 shift up to 40-mph. Then decelerate to a full stop. Repeat 20 timesPosted on by Rick Muscoplat
