I have a question on regarding my 2008 chevy colorado. i recently had my truck in for service due to the rear axle problems i feel need attention. during my observation. the tire on the driver side space between the wheel and the body of the truck is different from the passenger side. i cannot stick my hand in the driver side of the wheel and the passenger i can stick my hand and arm in. i was told this is normal and that there is no way that is so because the axle is one whole piece. i feel that when i drive the axle somewhat slides from side to side. my colorado was bought new. currently it has 20,300 miles on. *tr

Tl*the contact owns a 2008 chevrolet colorado. the contact has to repeatedly purchase new tires for the vehicle due to a design flaw. a certified mechanic inspected the vehicle and concluded that the front end altered the tire alignment, which caused them to fail. the dealer will not acknowledge that a failure exists; therefore, the vehicle has not been repaired. the vin was unavailable. the contact has possession of the failed components. the vin was unknown. the failure and current mileages were 10,000.
