CV Joint Repair
By regularly using a good service centre with certified technicians, a damaged boot will probably be detected before too much damage occurs. In this case, the technician will repack the joint with new lubricant and replace the boot.
The parts might not be too expensive, but the repair requires a significant amount of work, so you’ll end up paying a few hundred dollars to replace the boot. However, if you wait too long, you might need to replace the entire CV joint or maybe even the drive shaft, a much more expensive repair.
Unless you are an experienced mechanic, you probably shouldn’t consider joint repacking/boot replacement a DIY job.
A worn-out CV joint must be replaced – it can’t be repaired. You might be able to get hold of a reconditioned joint, but most likely you’ll end up with a new one.
You want the service center to ensure it is using the proper part for your vehicle and one that meets the OEM specifications. Cheap parts are a false economy, and should always be avoided.
Common CV Joint Problems
For smooth running, a CV joint uses a special lubricant that is packed in and then sealed by plastic or rubber boot secured with a pair of clamps. As long as that boot is undamaged, the CV joint should last a long time without maintenance.
It is more likely that your car will rust through before the CV joint goes. However, a damaged or cracked protective boot opens up a whole world of pain as lubricant spills out and water infiltrates the joint.
This causes the CV joint to corrode and fail. Outer boots seem to be the more vulnerable ones, probably because they must withstand more motion than do the inner boots.
A properly trained and certified technician will inspect your CV boots for tears, cracks and other damage whenever you bring your vehicle in for scheduled care.
