One problem related to axle assembly has been reported for the 2003 Chevrolet Silverado. The most recently reported issues are listed below.
The locking rear axle on my Chevrolet Silverado 2500hd does not release when entering a turn or intersection from a stop, causing the vehicle to continue forward and fight steering in the proper direction. I have had several near head on collisions with opposing traffic upon finally completing the turn. Chevrolet inspected the rear axle and installed a lubricant additive at approximately 10000 miles but the problem still exists. I have spoken with other owners of the same make,model,and year vehicle who have similar problems.
