I purchased a 2003 trailblazer from an individual. The front differential had a hole in it. So I purchased a differential from a scrap yard. 90 day warranty. Still had a noise . I still had a noise front differential was out again. I purchased the third differential from a different yard took it apart . Found the driver side bearing bad. It seems to be a very common problem because the driver side drivers constant. I was wondering if there is a recall. I see a lot of complaints online. Thank you there was a fire the differential grease burnt bearing went out and chard motor and surrounding area no real damage.

There is a strong odor of gasoline vapors coming from the rear of the vehicle, a crack can be seen in the neck of the fuel tank. When filling the vehicle, fuel spills out of the tank from the crack. The fuel gauge cluster in the dash doesn't work. The blower on the A/C unit doesn't work on the highest (5) level. Also, the fan clutch went out causing the car to overheat severely. The fan does not engage, causing the water pump shaft to become damaged. Also, the rear driver side window quit functioning, despite buying an expensive new regulator and replacing it. Having researched the issues, I find that I am among hundreds, possibly thousands of unsatisfied people with the same problems.
