I dont mean to be pessimistic but the same son of a ***** cost me a bi-lateral knee operation, so good luck and fingers crossed.
If will recap what I did, if I can well recall:
Anti-roll bar droplink removed
Cross bolt for suspension fork removed and fork separated from lower wishbone
Track rod ball joint seperated - gives infinitely more maneouverability and you will definitely need it!
Upper Wishbone balljoint cracked and removed.
Lower Wishbone balljoint obviously cracked to allow you to replace the arm
Lower wishbone balljoint into hub - dont attach a nut, but be very careful
Swing the rear part of the wishbone into place(rear = towards back of car, front = towards front of car). From memory this took some very significant maneouvering of the arm, more than I ever expected including pulling the thing up and toward me and taking the hub weight.
Swing the front into place again I cant quite remember but this took significant maneouvering. You have to be strong and scrape all your knuckles im afraid.
You then should be able to fasten things up from there. Was in Manchester before I moved to France, sorry cant help now.
