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.
