The outer CV joint is non-serviceable, and if damaged, the entire driveaxle and outer CV joint assembly must be replaced. For boot replacement, the inner CV joint and boot are removed, and a new outer boot is installed, ensuring proper packing with grease and securing the boot with clamps. This replacement is considered when the outer boot is damaged or worn.

The procedure involves positioning a floor jack under the axle arm, compressing the front coil spring slightly, and removing its lower portion secured to the axle beam. This is done to relieve tension and facilitate the removal of the coil spring.

The axle identification number is located on a small metal tag near one of the cover bolts.
