What should be done with CV-joints showing external damage?

When CV (Constant Velocity) joints show external damage, immediate replacement is the appropriate course of action. This is crucial because CV joints play a vital role in transferring power from the engine to the wheels while allowing for smooth turning and suspension movement. External damage could indicate that the protective boot has been compromised, potentially allowing dirt and moisture to enter the joint. This contamination can lead to premature wear and failure.

Given the risk of deteriorating performance or catastrophic failure while driving, addressing visible damage without delay is essential. Continuing to use a damaged CV joint can worsen the condition, leading to more extensive and costly repairs later on. Therefore, immediate replacement is the safest and most effective option to ensure the integrity of the drivetrain and vehicle safety.

Options involving further inspection or cleaning and reuse may not be sufficient, as damage often compromises the integrity of the joint. Likewise, doing nothing is not advisable, as it can lead to greater vehicle failure and safety issues down the line.
