Local parts stores, dealer parts counters and online parts sites sell them. Most shops replace the whole axle rather than one joint.
Professional insight
Mechanics usually fit a complete axle. Rebuilding one joint takes longer and saves little.
- Confirm left or right, and front or rear.
- Count spline teeth on the old shaft.
- Check for an ABS tone ring on the outer joint.
- Use the new axle nut, never the old one.

Types
| Joint | Position | Key trait |
|---|---|---|
| Rzeppa ball joint | Outer, at the wheel | Handles steering angles near 45 degrees |
| Tripod joint | Inner, at the gearbox | Slides in and out as the suspension moves |
| Double cardan | Driveshafts and steering | Two U joints back to back |
Signs it needs replacing
- Clicking when turning at low speed.
- Clunk when shifting into drive or accelerating.
- Vibration that grows with speed.
- Grease sprayed inside the wheel from a torn boot.
Repair or replace?
A torn boot caught early may only need a boot kit. A clicking joint is already worn, so replace the axle.
Tools you will need
- Jack and rated jack stands.
- Large axle nut socket and breaker bar.
- Torque wrench for the axle nut spec.
- Pry bar to pop the inner joint out.
- Drain pan for gearbox fluid.
Common questions
- Are remanufactured axles worth it?
- They can be. Check the warranty and that both joints were rebuilt.
- Should I replace both sides?
- Not always. Replace the side that is worn, and inspect the other.
- What is a CV boot?
- A rubber cover that keeps grease in and dirt out.
