Jeep Differential Oil Seal 16521.10 Omix ADA for Dana 35 1976-2007

Description

Product Overview

The Omix ADA 16521.10 oil seal is a precision‑engineered component designed to protect the front pinion of Jeep differentials that use a Dana 35 gear set. Constructed from a high‑grade synthetic rubber compound, the seal offers superior resistance to heat, oil, and abrasive particles, ensuring a long service life even under the most demanding off‑road conditions. The seal measures 3.5 x 3.5 x 1.5 inches and weighs just 1.44 ounces, making it lightweight yet robust enough to handle the torque and pressure generated by the drivetrain. Its design incorporates a reinforced steel backing that maintains shape and prevents extrusion, while the lip profile is optimized for a tight fit against the housing, eliminating the possibility of oil leakage. The product carries the OEM part number 83504946 and is fully compatible with the original equipment specifications, providing a direct replacement that meets or exceeds factory standards.

In addition to its core functional attributes, the Omix ADA oil seal features a low‑friction inner surface that reduces wear on the rotating shaft, contributing to smoother operation and lower maintenance costs. The seal’s material composition also offers excellent resistance to ozone and UV exposure, which is particularly important for vehicles that spend extended periods outdoors. With a limited five‑year warranty, Omix ADA stands behind the durability and performance of this component, giving customers confidence in their purchase.

Usage

This oil seal is intended for use on a wide range of Jeep models produced between 1976 and 2007, including the CJ, YJ, TJ, JK, XJ, ZJ, MJ, and SJ series. It is specifically engineered for applications where a Dana 35 differential is installed, making it an ideal choice for both original equipment installations and aftermarket upgrades. Whether you are restoring a classic Jeep for daily driving, preparing a vehicle for off‑road adventures, or performing routine maintenance on a work truck, this seal provides reliable protection against oil loss and contamination.

Installation is straightforward for experienced mechanics and DIY enthusiasts alike. The seal fits into the standard front pinion housing without the need for additional machining or modification. It is recommended to clean the housing thoroughly, apply a thin layer of compatible grease to the seal lip, and ensure proper alignment before pressing the seal into place. Once installed, the seal will maintain a consistent oil barrier, preventing the ingress of dirt and water that can cause premature wear on internal gears.

Typical usage scenarios include heavy‑duty off‑road excursions, where the differential is subjected to high torque loads and exposure to mud, sand, and water. The seal’s robust construction also makes it suitable for high‑performance applications, such as modified Jeeps equipped with larger tires or lift kits that increase drivetrain stress. In all cases, the Omix ADA oil seal delivers dependable performance, helping to keep the differential lubricated and operating smoothly.
