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

Eliminate rear differential fluid leaks, prevent oil contamination, 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, seal swap, 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 high torque loads. Reusing a stretched pinion nut or a previously compressed crush sleeve can cause the pinion assembly to back off, leading to catastrophic gear mesh failure, severe drivetrain noise, and vibrations. This premium hardware replacement kit ensures a factory-grade seal and a robust mechanical lock that holds up to rugged off-road terrain, highway commuting, and heavy 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, uniform crush collapse, and long service life.

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