2003 Chevrolet Trailblazer Owner Comments

problem #1

Feb 192004

Trailblazer 4WD 6-cyl

  • Automatic transmission
  • 8,500 miles


While putting the Trailblazer into any gear it makes grinding noise in rear. While driving to the dealer the rear of the Blazer was all over the road. It felt like the rear wheels where going to fall off. While still many miles away from dealer for service the back axial locked up making me loose control. This was at 25 mph. Thank goodness I did not take the highway. I donT want to know what would have happened at 65 mph. I had to have towed to dealer from there. I was told that a bearing breaking caused this. However first I was accused of having the vehicle 4 wheeling.
