    Quick Boot - CV

    Inspect/Replace

    To check the condition of the boots:

    • Look for splits, cracks, tears, punctures, or thin spots caused by rubbing. These call for immediate boot replacement.
      • Tears in the boot are an obvious sign of failure requiring that extra care be taken when cleaning and greasing the boot during replacement.
      • Small cracks in the rubber or collapsed bellows that allow the boot to rub on moving parts or the joint are early signs the boot will fail.
    • If the boot appears rotted, this indicates improper greasing or excessive heat, and it should be replaced.
    • Squeeze all boots. If any air escapes, replace the boot.
    • If the inner boot appears to be collapsed or deformed, venting it (allowing air to enter) might solve the problem.
    • Place a round-tipped rod between the boot and drive shaft.
    • This equalizes the outside and inside air and allows the boot to return to its normal shape.
    • Make sure that all boot clamps are tight.
    • Missing or loose clamps should be replaced.
    • If the boot appears loose, slide it back and inspect the grease inside for possible contamination.
      • A milky or foamy appearance indicates water contamination.
      • A gritty feeling when rubbed between the fingers indicates dirt.
    • In most cases, a water- or dirt-contaminated joint should be replaced.
