Took my truck in for state safety inspection. i was told that my right front hub & bearing assembly had excessive play. i now have 69,587 miles, at 32,000 miles the same problem arose with the left front hub & bearing assembly which was covered by warranty under gm's 36,000 mile 3 years warranty. this defective hub & bearing assembly just cost me $553.81. this part cannot be lubricated or adjusted. i had some sway when towing my travel trailer and thought it was the roadway, but now i know it was a defective part. what would have happened next? the wheel assembly falling off? or causing an accident. i have been driving for over 45 years and never heard of such a problem. two front hubs wearing out in such a short time. if this was something that needed lubrication or adjustments i could understand. but nothing an owner can do. i feel this is a safety item that could have caused an accident. by the way i still have the original brakes at 69,000 miles but had two hub bearing assembles go bad!! *tr
