NOTE For Highlander and RAV models see Toyota Awd Rwd Rav article

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

The inner CV joint is a plunging tripod joint. The plunging action allows for axle shaft length change as suspension moves up and down.

The inner and outer CV joints are enclosed by a CV joint boot. The boot maintains lubrication in the joint and prevents contamination of lubricant. Boots must be replaced if leaking or cracked. The inner CV joint can be repaired. The outer CV joint must be replaced as an assembly.
