What components are included in this Yukon Minor Install Kit?

This kit includes a pinion seal, a crush sleeve, a complete shim kit for gear adjustment, and marking compound with a brush for checking the gear pattern. These are the essential parts needed for a ring and pinion gear change when reusing the original bearings.

Can I use this kit if my differential bearings are worn out?

This is a 'minimum' installation kit, meaning it's designed for situations where the original bearings are still in good condition and can be reused. If your bearings are worn, you would need a full installation kit that includes new bearings.

What is the purpose of the crush sleeve and shim kit?

The crush sleeve is used to set the correct preload on the pinion bearings, which is critical for bearing life and gear meshing. The shim kit allows for precise adjustment of the ring gear's position and backlash, ensuring the gears mesh properly for quiet operation and durability.
