Note: For vehicles with ABS, pull ABS wheel speed sensor out slightly when removing.

- Disconnect drive axle from transmission flange.
- Press drive axle upward toward front of vehicle.
- Turn steering to full lock and remove drive axle.

Installing

Clamp drive axle in vise with jaw covers.
Remove clamp.
Push back boot.
Turn in M16 threaded end of special tool 3207 until CV joint is pressed off splined shaft.
graphic
Attaching the CV joint boot onto the outer body of the joint frequently requires compressing or squeezing the boot. This produces a vacuum in the joint boot, which may cause a crease to the inside when driving (arrow).
For this reason, after installing the joint boot, vent it briefly by letting some air in at the small diameter end, thus creating a pressure balance and restoring the correct boot shape.
