What It Helps Fix
- Clicking or popping during turns caused by a worn CV joint
- Vibration from a damaged or out-of-balance axle shaft
- Torn boot conditions that can lead to grease loss and joint wear
- Axle noise from worn spline or joint interfaces
- ABS-related driveline service needs when the tone ring is part of the application
