I have just DIY'd my cv joint rubber boot replacement 3 months back and I did have the whole half shaft removed off the car.I suppose you can do a re-lube of the CV joint in-situ if you want to.Just loosen both the metal clamp ring and slide the whole boot towards the diff.Best to have the tyres suspended so you can give a thorough cleaning of the cv joint ball bearings.Originally Posted by ryan roopnarine
