Inspect Constant Velocity (CV) Joint Boot and Test CV Joint
Inspecting Boot
Inspect CV joint boot after every 200 hours of operation.
A torn boot is the most common cause of CV joint fail­
ures.
Note: A worn and noisy CV joint with the boot in good
condition and filled with grease is not uncommon. Pot­
holes, curb contact, or collision damage can chip bear­
ing components and initiate worn conditions.
1. Look for grease on the suspension, inner tire side ­
wall, or fender to indicate a possible torn boot. Inspect
boot for cracks, holes, tears, or loose clamps. Dirty
grease within the boot may indicate damage to the CV
joint.
2. If the boot is cracked or torn, or has any holes or
loose clamps, remove and inspect CV joint (see
Constant Velocity Joint).
Testing for Outboard Joint Problem
1. Test drive vehicle on a smooth surface to verify
problem.
2. Accelerate or back–up vehicle slowly with the
wheels turned. Listen for snapping or clicking noise at
the wheel, then drive straight ahead.
A. If the noise remains constant, the wheel bearing
is the likely problem (see Front Wheel Bearing).
B. If the noise gets louder when turning, the out­
board CV joint is worn. A badly worn joint will snap or
click when driving straight ahead, however the
noise will increase when accelerating or backing up
into a turn. Remove and inspect CV joint (see
Constant Velocity Joint).

Testing for Inboard Joint Problem
1. Test drive vehicle on a smooth surface to verify
problem.
2. Accelerate vehicle quickly and straight ahead.
Vibration or shudder indicates a worn or sticking inboard
CV joint.
3. Accelerate vehicle at an angle over a ramp or up an
hill. A clunking noise indicates a worn inboard CV joint.
4. Remove and inspect CV joint (see Constant Veloc ­
ity Joint).
