Front Wheel Diagnosis Procedure
1. Grease Under Front of Vehicle (No Noise)
Diagnostic Procedure — Boot examination
- A torn boot is the most common cause of CV Joint failure
- Grease on suspension, inner tyre sidewall or fender will indicate a torn boot.
- A small cut or tear; the grease is clean and the joint is not making any unusual noise… Install a Boot Kit.
- A large tear; the boot nearly gone; the grease is contaminated or no grease in the joint. The CV Joint will probably need replacing.
2. Snapping or Clicking coming from wheel when accelerating around a corner
Diagnosic Procedure — Outboard Joint Problem.
Test drive the vehicle on a smooth surface and verify the problem by:
- Lightly accelerate or back up with wheels turned; Listen for snapping or clicking noise at the wheel.
- If noise remains constant or disappears — the Wheel Bearing is the Problem.
- If the noise gets louder, the CV Joint is worn.
- A badly worn CV Joint will snap, click or vibrate when Driving Straight Ahead.
- Install a new CV Joint and Boot Kit (Service Kit) if the problem is positively identified as the outboard CV Joint.
3. Clunk or Vibration when excelerating or deaccelerating
Diagnostic Procedure — Inboard Joint Problem
- Test Drive vehicle on a smooth surface, accelerating hard straight ahead.
- A vibration or shudder indicates a worn or sticking inboard plunge joint.
- Accelerating over a driveway ramp at an angle.
- A clunking noise indicates a worn inboard joint.
