Motive Gear Rear Differential Pinion Bearing Kit

Description

Product Overview

The Motive Gear Pinion Bearing Kit is a complete solution designed specifically for the rear differential of Dana 44 Nissan applications. Constructed from machined steel components, the kit includes Timken‑grade pinion bearings, a precision‑engineered pinion seal, a crush sleeve, shims, a pinion nut, and a thread‑locking compound. Each part is manufactured to tight tolerances to ensure optimal gear mesh and minimal axial play. Weighing just 4 pounds and measuring 11.3 x 12 x 2 inches, the kit fits seamlessly into the existing housing without modification, delivering a balance of strength and lightweight performance.

FAQ

Will this kit fit a 2005 Nissan Frontier with a Dana 44 rear axle?

Yes, the kit is engineered for the standard Dana 44 rear differential found in most Nissan trucks and SUVs, including the 2005 Frontier. Always verify the pinion gear size and gear ratio to ensure compatibility.

Do I need any special tools to install the kit?

Installation requires common hand tools such as a torque wrench, socket set, and a bearing press or a suitable bearing installer. No proprietary tools are needed.

Can I reuse the existing pinion seal?

We recommend replacing the seal with the new one included in the kit to ensure optimal oil retention and to prevent future leaks.

How often should the pinion bearings be inspected after installation?

For street use, inspect the bearings at every major service interval (approximately every 30,000 miles). For track or high‑performance use, check them after each event or every 5,000 miles, whichever comes first.
