As Track/Kick owners have noticed, the number of aftermarket traction aids available for the larger rear third member is rising. With the growing number of hybrid rear axles available for the Samurai, this makes the Sammy owners ears perk up as well. We prepared this Tracker differential, stuffed with factory 5.12 gears, for the Sidewinder/ARB project we started last month. 

ARB has an air locker to fit both ring and pinion combinations that are found in the rear diffs from 1988 and up. From 1988 to 1993 Suzuki used a 10 bolt ring, this uses ARBs RD74 model. In 1993, Suzuki started putting a 12 bolt model into the rear differential. This is what we were working with, so ARB supplied the RD79 model for this installation. Both flavors of ring gear were used in 1993, so if you have any question as to what you have, there is a quick way to find out without pulling the whole thing apart.

On the drivers side of the differential, there is a speed sensor that is held in with a 12mm bolt. Remove the sensor and look inside with a flashlight. Mark the first bolt head you see with a marking pen and then rotate the pinion. Count the bolts as they go by... Of course this is easier when the axle is out and in the shop, common sense says that you don't try this on the vehicle with the tires on the ground.
