Spicer Rear Pinion Seal, Nut & Crush Sleeve Overhaul Kit for Jeep (Dana 35)

Eliminate rear differential fluid leaks and restore proper pinion bearing preload with this genuine Spicer Pinion Seal, Nut, and Crush Sleeve Kit. Specifically bundled for classic Jeep Wrangler, Cherokee, Grand Cherokee, and Comanche models equipped with a Dana 35 rear axle housing, this service kit includes the essential high-wear hardware items required during a yoke replacement or gear service.

The pinion seal prevents vital gear oil from escaping past the spinning yoke, while the crush sleeve and pinion nut establish the exact rotational preload required to keep your pinion bearings tracking smoothly under heavy torque. Reusing a stretched pinion nut or a compressed crush sleeve can cause the assembly to back off, leading to catastrophic gear mesh failure and severe noise. This premium hardware replacement kit ensures a factory-grade seal and standard mechanical lock that holds up to rugged off-road terrain, highway commuting, and trail use.

Kit Highlights:

• Complete Hardware Solution: Bundles one premium rubber-lipped pinion fluid seal, one heavy-duty crush sleeve, and one self-locking pinion nut.

• Genuine Spicer OEM Quality: Engineered to precise factory tolerances and steel-grade specifications for exceptional thread reliability and long service life.

• Crucial Service Item: Essential replacement hardware whenever changing a damaged pinion yoke, replacing a leaking seal, or installing new ring and pinion gears.
