Front Outer CV Boot & Rear Wheel Bearing Bushes - Replacing

[steamship]

Thankfully because of a couple of days of dry weather, I've finally had a chance to get under the car and check things out prior to the MOT.

I was aware of a slight knocking from the rear at very slow speeds on a lane, so it wasn't a surprise to see that the rear left lower bushes (#2 in the attached image) were considerably worse than the previous time I checked them. I've already ordered the parts, but just wondering if anyone has ever changed these in situ?

The other end of the car has a different issue. The front right outer CV boot has a split in it, about two inches long. The area around it is still perfectly free from grease, but again I'm wondering if anyone has done this in situ. Also, I've the option of using one of those CV boot expanding tools to put on the new one, or I can dismantle the CV joint itself. I'm not keen on the latter option for a number of reasons.

I've already got the relevant PDFs from the Tech Dump thread and will be scouring through them later.
