The 2002 Chevrolet Z71 and 2002 4x4 models typically come equipped with a 10-bolt rear axle, which is common for these trucks. Depending on the specific configuration and options, they may also feature a 14-bolt rear axle, especially in heavier-duty variants. It's important to check the vehicle's specifications or look for the RPO (Regular Production Option) codes to confirm the exact rear axle type.
