4. Repeat this course of for the second bolt.
5. As soon as each bolts are free, rigorously use a ball joint fork to separate the ball joint from the management arm. You’ll be able to strike the fork with a hammer if wanted to interrupt any rust or particles that could be binding the joint.
With the ball joint efficiently disconnected, you may proceed to the following step of the CV axle boot alternative course of.
| Device | Utilization |
|---|---|
| 17mm socket | Unbolt the 2 bolts holding the ball joint to the management arm |
| Breaker bar | Improve torque for loosening bolts |
| Ball joint fork | Separate the ball joint from the management arm |
Changing the CV Axle Boot Band
Preparation
Park the automobile on a stage floor and have interaction the parking brake. Collect the mandatory instruments and supplies, together with a brand new CV axle boot band, a pair of pliers, a screwdriver, and a hammer.
