I picked up a front auto locker off Geeves who originally got it of Lewis.
Was from an MU so the diff mounts were different so you can't swap a complete MU diff into a Bighorn.
Swapped the locker over into my diff and got it running. Took longer than expected. Had to drop the lower balljoint on each side, take hub apart and remove lock ring off axle, disconnect the inner CV lock ring, withdraw axles. Undo steering draglink and remove. Undo four diff mounts and lower diff out.
Reassemble in reverse.
Went for a hard run yesterday, diff just crawled up everything. Was really awesome. Turning at low speed can be very difficult. Tight corners are a pain, they always were with my LWB but even more so now. Worth the trade off though.
Had to do a few recoveries of capable trucks, Patrol and Pajero both well kitted out. Locker is great.
Thinking about a front locker, do it.
Matt.
