I have done one side , it took me 45mins. Straight forward job, the joint freed off with a couple of taps. I was then able to leaver it down to get the old boot off and the new one on.
I have just taken the nut off here.
I cleaned it up well after taking the old boot off before re-greasing
The old and new boots. The new boots were £2 each
Job done, these boots had o rings to hold them on..
