Ive just done mine for MOT.

It failed as the balljoint was worn and produced a knock with the slightest of movement of the steering wheel.

Easy to do- x2 19mm spanners, put one on track rod end

(connected to hub) and other on the end rod and rotate this rod until it comes out of the track rod end

(it helps if you turn the steering wheel to gives more space).

Then as above use mole grips or ideally, variable width pliers and undo.

Piece of pi*s.

Might be worth getting your tracking done afterwards.

People will say

"mark the number of threads before you undo the 19mm bolt" but you'l struggle to get it spot on, best paying for the tracking.

Hope this helps.
