When changing UJ's on rear half shaft, I know most people take the whole thing out, but you can change them out without removing the shaft!
This is how I did it… jack up the car, remove the circlips, drill a hole in the back of outer bearing cup, now you need to have a tap & die set for this, use at least a 4 mm hole. Tap a thread into it & screw in a suitable bolt. As you wind in in, it pulls the outer bearing cup out of the shaft.
Once all 4 are out, just wiggle the joint around. The center part of UJ will fall out (if you remove the 4 bolts connecting to center of axle.)-Richard from Spitfire/GT6 Magazine
