Spicer Differential Rebuild Kit P/N:10040312
DANA SPICER CHASSIS 10040313 front differential rebuild kit for the 2018-2022 Jeep Wrangler replaces the worn bearings and oil seals in the Dana 30 front axle.
Whining from the front axle, lube leaking past a seal or play at the pinion can mean the bearings or seals are worn, though a worn ring and pinion gear set or a bent axle shaft can be behind the same noise, so track down the source before ordering. The 2018-2022 Jeep Wrangler takes one kit.
This kit fits the front Dana 30 axle of the 2018-2022 Jeep Wrangler.
