With the axle all back together, including new seals from Spidertrax, I was almost ready to go wheeling. Gear break-in is another important step when changing ring-and-pinion ratios. Proper break-in involves running the vehicle a short distance to heat up the gears and then letting them cool. On the Samurai I tried a new method by simply putting the truck up on jackstands, and letting the axles spin for 30 minutes in gear, before doing the same in reverse. Then I changed the gear lube and all was ready to go. Next month we hit the dirt to see how a true 4x4 compares to the Rhino.
