its not the VC its the half shafts. AKA cv joints, your VC repair only hid the issue due to a smoother power transfer. they are not rebuildable, and are sold as side specific assemblies. make sure you pick up a set of spline sockets, (don't recall if its metric or sae but they are relatively inexpensive at harbor freight) if you intend to do it yourself, as well as a couple cans of brake cleaner and PB Blaster, the brake cleaner to degrease the bolts so the Blaster can penetrate. I don't recommend a torch if at all possible, unless you have a good oxy acetylene with a fine tip, due to the area you will be working. it can be a bit tight and you don't want to light up any grease from the rod ends...
The irony is YOU cant rebuild them, but you can buy rebuilt units... if you can figure that out let me know ( I know, special tooling required, but Ive seen this on parts that DONT require special tooling like some starters and alternators... profiteering at its finest)
