Section 249 (Axle Shafts): Description
WARNING: This page is about a different car, the 2003 Toyota Prius and 2002 Toyota Prius. However, it is still accessible from the selected car via links, so may be relevant.
Axle shafts transfer power from transaxle to front wheels. All axle shafts consist of a shaft with a flexible Constant Velocity (CV) joint at each end. Inner CV joint is splined or bolted to transaxle. 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 CV lubricant. Boots must be replaced when signs of leakage or cracks are present. The inner CV joint can be repaired without replacing assembly. The outer CV joint must be replaced as an assembly.
