They may eventually update a part (discover a design flaw) or develope a repair but at this time choose to say it's normal. Go over [#PI01273B - (09/15/2003)] with anyone else that drives your blazer and the service technician at goodwrench to determine if the symptoms match the bulletin."""

WHAT A P. O. S.!! I wouldn't buy another GM product for nothing!!
Great information to know.. I've read from the rear wheel axles seperating at 55mph to the rear end seizing and rolling the vehicle. Going to trade it in I believe.
