Mopar 68398740AA Dana 44 Pinion Nut for 18-24 Jeep Wrangler JL & Gladiator JT

The Mopar Pinion Nut is a factory replacement for the front and rear Dana 44 axles found on JL Wranglers and JT Gladiators. When you are servicing threaded drive train parts that are subjected to heavy loads while driving it is always a good idea to get new parts. A fresh set of threads on both parts will assure the parts are joined firmly and the threads have not been weakened by previous torquing. The pinion nut should be treated this way as it is a valuable part to keeping your drive line tight and in place.
