FYI - It's easier to replace the tie-rod end with the wheel off, however this is not necessary.
1. Remove the top lock nut using 17mm spanner or socket (a).
2. Loosen the lock nut and then unscrew anti-clockwise to remove tie-rod end (b).
3. Install new tie-rod end and reattach tie-rod to the spindle using 19mm spanner and 24mm spanner.
TIP: If ball joint spins and the nut will not tighten, apply pressure from bottom side of the ball joint to lock ball joint in place.
