2003 Chevrolet TrailBlazer LS review from North America

I just had to rebuild the front differential on my 2004 Trailblazer at a cost of $2,098!

The Chevolet dealer said the cause was different brands of tires between the front and back (not different size). I had to replace the rear tires recently and bought the same tires as originally installed. I then had to replace the front tires shortly after that, but could not buy the same tires because they had been discontinued. I had a mixed set of tires on the vehicle that were very new.

A few months later some terrible noise was heard when I shifted in A4WD. The road conditions were slippery – snowy. It seems to me that if the 4WD system on the Trailblazer is so sensitive to different tires GM should say so. People (like me) could avoid the possibility of that kind of problem.

Also, the Chevrolet dealer has a sign prominently posted above their service area that says they are not satisfied unless the customer is satisfied. I'm certainly not satisfied. While my complaint has more to do with Chevrolet than them, they could do more to get GM to be truthful about the tire requirements for the Trailblazer. There isn't anything in my Trailblazer manual to suggest the potential problem.

How about other 4WD vehicles?

Up until this time, I have liked the vehicle.
