With all that being said, installing and initially adjusting the cable does take care. It is not rocket science. If you follow the instructions the lockers will work perfectly. This is what I did when I initially installed them over 56,000 miles ago. I never had to go back and readjust or mess with anything.
A few quick pictures. This does NOT take the place of the instructions.
This is the differential end of the shifter cable. The threaded rod attached at the end of the cable threads into the shift fork. Use thread locker here.
The instructions say to thread it in so that one or two threads show. But, the picture shows 3-4 threads showing. I do 3-4 threads sticking out.
The shifter end of the shift cable. It has the longer threaded end on it.
After installing the cable into the diff cover, I installed the differential cover, making sure that the shift fork slides into the collars notch. Not hard, but care is needed.
I then route the cable back to where the shifter is mounted, securing the cable as I go. No tight bends, avoid pinch points, hot stuff, stuff that moves, sharp stuff, etc.
Once the cable is back close to where the shifter mounts, I then adjust the other end of the cable and install it into the shifter.
This measurement is critical. I use a caliper to make sure I get this 5/8". Eyeballing it or "close enough" is not good enough here. Take your time, do it right, you will get years of trouble free operation. Do a rush job and you will have problems.
Both of my shifters mount to a steel bracket that is bolted on the driver side of the transmission tunnel, between the gas pedal and AX15 shifter. Not in the way of anything, but very easy to reach. While I do love the location, it does make it a pain to route the front cable and adjust it, since it is above the exhaust and in between the transmission and the side of the transmission tunnel. Even though it is not the easiest location, I am able to properly adjust and route the cable clear of the exhaust. So, because it is a PIA, I make sure I do it right the first time.
Anyway, did the initial adjustment, jacked the front wheels off the ground, locked in the hubs, engage the locker, turned a tire a little bit, locker instantly locked. Shifted to unlock, turned a tire, diff unlocked almost instantly. Repeated this about 20 times, worked perfect every time.
Hope to get 50,000 miles out of this cable!!!!
The front shifts like butter. The rear still shifts great, but not quite as buttery as the front. Damn OCD will probably have me installing a new rear cable soon enough!!!!!!
