lol, probably not the most positive product review ever, no. Maybe it was just my technique. They do say clamp the driveshaft securely in a vice - which I don't have so I ended up sticking it in beween the arms of my lowered engine hoist which secured it with the other end against the garage wall.
In my 1st post I was meant to say you have to pull so hard the cone gets stuck on the spider, also all ended up folding in on itself as it returned to it's original size after snapping off the end of the cone and was well hard to put right due to all the grease everywhere!
I didn't even bother doing anymore today, lazy I am.
