Pretty simple loosen the big locknut on the track rod first ( no more than 1/2 turn) then undo the nut holding the track rod end to the stub axle, either use a ball joint splitter, pickle fork or hit the side of the upright to shock the track rod end out.
Spin the track rod end of the track rod.
Undo the clips ,tie wraps or whatever is holding the gaiters on, slit/cut them off.
To fit new ones squirt a bit of lube on the nut & case of steering rack.
Slide gaiter on stretch over nut the secure in place.
Screw new trod end on upto nut, put pin back into upright, fit/tighten nut, then lastly retigthen lock nut, repeat for opposite side.
It's same as UK models.
