Unbolt the wheel and undo the hub nut - disconnect the hub from the wishbone / ball joint and undo the track rod end bolt and knock it out of the hub. Drain the gearbox oil. Then pull the hub towards you and pull the shaft out of the box. Pull the old gaiters off - you need to remove the outer one to fit the inner one ( cut them ) and the fit the new gaitors - there are 2 styles depending on the type of shaft fitted to your car - one has 3 prongs on the end and the other is circular. Simply pack the gaitors full of grease and repeat the process in reverse.
