Axle Shafts: Description

Axle shafts transfer power from differential to driving wheels. Axle shafts consist of a shaft with a flexible Constant Velocity (CV) joint at each end. Inner CV joint is splined to differential. Outer CV joint is splined to hub assembly and secured by wheel bearing hub nut.

CV joint boots protect CV joints by maintaining proper lubrication and preventing contaminants from entering joint. Boots should be replaced when leakage or cracks are present. Inner CV joint can be repaired without replacing the assembly. Outer CV joint should be replaced as an assembly.
