Servicing and diagnosing worn constant velocity joints

Servicing and diagnosing worn constant velocity (CV) joints on cars is an important aspect of maintaining the vehicle’s drivetrain and ensuring safe and smooth operation. CV joints are crucial components that allow the driveshaft to transmit power to the wheels while accommodating the up-and-down motion of the suspension.

Here’s a guide to servicing and diagnosing worn CV joints:

Diagnosing Worn CV Joints:

1. Noise: A common symptom of a worn CV joint is a clicking or popping noise, especially when turning at low speeds. The noise often comes from the side of the vehicle with the faulty CV joint.
2. Vibration: Worn CV joints can cause vibrations, especially during acceleration or at certain speeds. These vibrations may be felt through the steering wheel or the vehicle’s floor.
3. Grease Leaks: Inspect the CV joint boots for cracks, tears, or grease leaks. Damaged boots can lead to contamination and accelerated wear of the CV joint.
4. Clicking During Acceleration: A damaged CV joint may produce a rhythmic clicking sound during acceleration. This occurs as the worn joint clicks when it rotates.

Servicing and Repairing Worn CV Joints:

1. Inspection: If you suspect a worn CV joint, visually inspect the CV joint boots for damage and check for grease leaks. If the boots are damaged, it’s advisable to replace them promptly to prevent further issues.
2. Boot Replacement: If the CV joint boots are damaged but the CV joint itself is in good condition, you can opt to replace the boots. This involves removing the old boots, cleaning and repacking the CV joint with fresh grease, and installing new boots.
3. CV Joint Replacement: If the CV joint is significantly worn or damaged, it’s recommended to replace the entire CV joint assembly. Replacing the joint itself involves removing the driveshaft, separating the joint from the shaft, and installing a new joint.
4. Professional Mechanic: CV joint replacement and repair can be complex tasks that require specialized tools and knowledge. It’s advisable to have these repairs done by a qualified Autobahn technician who has experience working with drivetrain components.
5. Regular Maintenance: To extend the lifespan of your CV joints, it’s important to follow the manufacturer’s recommended maintenance schedule. This may involve checking and maintaining proper levels of CV joint grease and inspecting the boots for damage.
6. Quality Parts: When replacing CV joint components, use high-quality parts to ensure durability and reliable performance. OEM (Original Equipment Manufacturer) or reputable aftermarket parts are recommended.

An Autobahn professional technician can determine any issues or faults with your cars constant velocity shaft system and advise you on the best action to rectify the fault.
