A re-gear or diff rebuild needs fresh bearings, seals and shims to set up correctly. Wrangler JL, JK and TJ and Gladiator JT owners use install and overhaul kits to finish a gear swap or freshen an axle with a lot of miles.
This category includes master overhaul kits, install kits with bearings, races, seals and crush sleeves, and gear packages that bundle gears with the parts needed to install them. Kits are specific to the axle model and sometimes the carrier, so check the details before ordering. Using a complete kit means you are not reusing tired bearings or seals inside an axle that you have already taken the time to open up.
Shop install kits from Revolution Gear and Axle, Motive Gear, Yukon, Dana and Eaton. Need gears? See ring and pinion gears and lockers. Enter your Jeep in the vehicle selector to narrow the results to parts that fit your model and year.
