I started taking apart the CV joints. I need to use a brass punch (so I don’t dent the steel – the brass is softer) and manipulate the joint to get all the ball bearing out. Once out, the internal race can be removed and the joint cleaned out.
The axles are making a clicking noise while in 4WD and at full lock. Rebuilding the joints was the easiest option to seeing if it is the problem. If the clicking remains, at least I know the joints are in perfect order.
