Just spent my weekend replacing my CV boot on my 2005 108,000 miles 3.0d Sport. Instruction are great but I had a major problems, which I would like to share the solutions for:-

1) - Unscrewing the Collar Nut
2) - CV withdrawing from the hub
3) - Removing/re-attaching the CV joint from the splined shaft,

so here is some tips that worked for me.

1) - Unscrewing the Collar Nut - A 22" extending breaker bar woul not make it budge even with my full 240Ibs (110kg) body weight - I too another breaker bar and 3 Jubilee clips and fixed the two bars together giving be a 40" breaker bar, worked easily cost £1.80 for the clips.

2) - CV withdrawing from the hub - Used a 6" bearing puller with 3 claws. The claws hold onto the hub and screw onto CV joint end of the splined shaft, with lots of turns, giving more pressure than I thorght necessary, I then hit the bearing pullers screw. This made the shaft move, but several setups and attemps finally removed the CV joint.

3) - Removing/re-attaching the CV joint from the splined shaft - The splined shaft ( pic 6) which clearly shows the groove for the spring clip, needed to retain the CV joint. However the spring clip is difficult to get the CV joint passed. I used a Jubilee clip to squeeze the ring flush with the splines. When the CV joint is forced onto the shaft it passes over the spring clip and forces the jubilee clip further up the shaft where it can be unscrewed and removed easily.

Hopes this helps
