Axle Shaft Oil Seal Dana 50/60 2.88 ID x 4.464 OD

The Axle Shaft Oil Seal Dana 50/60 2.88 ID x 4.464 OD is a critical wear component for heavy-duty Dana 50 and Dana 60 rear differentials. This outer lip seal prevents contamination and fluid loss at the axle shaft interface, protecting gear oil from dust, mud, and water ingress. Heavy truck operators, off-road enthusiasts, and fleet maintenance teams rely on this seal to maintain differential integrity and extend drivetrain service life.

Engineered from a durable rubber and steel composite, this seal features a precisely molded lip design that rides against the axle shaft surface to create a dynamic barrier against contamination. The 2.88-inch inner diameter (ID) matches the shaft journal exactly, while the 4.464-inch outer diameter (OD) ensures secure press-fit installation into the axle housing bore. The natural rubber compound provides superior sealing performance across a wide temperature range, resisting both thermal cycling and gear oil exposure while maintaining elasticity under continuous axle articulation and movement.

Replacement is essential when leakage appears around the axle flange, bearing play increases, or the seal shows visible cracking during routine servicing. This seal fits Dana 50 and Dana 60 axle assemblies commonly found in 1-ton pickup trucks, commercial chassis, and heavy-duty work vehicles. Proper installation requires careful shaft cleaning and use of bearing installer tools to avoid damaging the lip seal during press-fit.
