Yukon AMC 35 / GM 8.2" Rear Axle Bearing & Seal Kit - Timken
AK SET9
The Yukon Bolt-In Rear Axle Bearing & Seal Set is designed for compatible AMC Model 35 and GM 8.2" rear axle applications that need new axle bearings and seals during a rebuild or repair. Built around a Timken tapered roller bearing, this kit helps restore proper axle shaft support and sealing when worn bearings, axle noise, or leaking seals need attention. It's a practical replacement for classic cars, Jeep trail rigs, restorations, and compatible rear axle assemblies that use a bolt-in bearing configuration.
Tapered roller bearings are designed to support both radial and axial loads, making them well suited for compatible axle assemblies where bearing support and correct installation are important. This Yukon kit includes one bearing and one seal to service a single axle side without purchasing unnecessary components. Whether you're replacing a worn bearing or refreshing an axle during a larger drivetrain project, inspect the axle shaft bearing surface, housing, and retaining hardware before installation to make sure the new components have a solid foundation.
Includes:
- (1) Timken Tapered Roller Rear Axle Bearing
- (1) Rear Axle Seal
Important: This kit services one axle side. Order quantity (2) to service both sides of a compatible rear axle. Designed for specific bolt-in bearing applications; verify axle identification and bearing configuration before ordering.

FAQ
What comes in the Yukon AK SET9 axle bearing kit?
This kit includes one Timken tapered roller axle bearing and one axle seal. It is designed to service one side of a compatible rear axle assembly.
What is the advantage of a tapered roller axle bearing?
Tapered roller bearings are designed to support both radial and axial loads. When used in a compatible axle assembly, they provide stable axle shaft support and dependable operation under normal driving and drivetrain loads.
Will this kit fit my AMC Model 35 rear axle?
This kit is listed for select AMC Model 35 rear axle applications, but the axle model alone does not guarantee fitment. Verify the bearing configuration, axle shaft dimensions, and retention method before ordering.
Will this kit fit a GM 8.2" rear axle?
It is designed for compatible GM 8.2" rear axle applications using the specified bearing configuration. Because GM rear axle designs vary by model and production year, confirm the installed axle and bearing dimensions before purchasing.
Does this kit include bearings and seals for both sides?
No. One kit includes one bearing and one seal for a single axle side. Order quantity (2) if you're servicing both sides of a compatible rear axle.
What does bolt-in axle bearing mean?
A bolt-in bearing configuration uses an axle bearing retention arrangement designed for the specific housing and axle shaft assembly. It differs from other axle designs that use internal C-clips or different bearing retention methods. Always match the replacement bearing to the original axle configuration.
What causes rear axle bearing failure?
Common causes include age, contamination, insufficient lubrication, damaged axle shaft bearing surfaces, improper installation, and excessive loads. A worn bearing may produce noise, vibration, or unwanted axle movement, while a damaged seal can allow lubricant to escape.
Should I replace the axle seal when replacing the bearing?
Yes. Replacing the seal during bearing service is good practice, especially when the original seal has been disturbed or shows signs of wear. This kit includes both components so they can be serviced together.
What should I inspect before installing a new axle bearing?
Inspect the axle shaft bearing surface, housing bore, seal contact area, and retaining components. Look for grooves, scoring, corrosion, or other damage that could shorten bearing life or prevent the new seal from working correctly. Follow the manufacturer's installation procedures for the specific axle.
