Description

The Yukon Bearing Kit, model BK T8-A, from Zumbrota Drivetrain provides essential components for differential rebuilds. This kit is specifically engineered for '85 and down Toyota 8" differentials and is also compatible with all aftermarket 27 spline ring & pinion gears. It offers a cost-effective solution for professional shops and builders who maintain a stock of shims, allowing them to bypass the need for a full Master Overhaul kit. Included within this kit are all the necessary bearings and races for both the carrier and pinion, ensuring a complete installation. Additionally, it contains a new pinion seal to prevent leaks, a crush sleeve for proper pinion pre-load adjustment, and marking compound with a brush for precise gear pattern analysis. The kit features a 45mm carrier bearing inner diameter, as specified in the technical notes. This bearing kit is suitable for Toyota 8" differentials with 4-cylinder engines, specifically those manufactured in 1985 and earlier. It also fits 1986 and later models that have been equipped with an aftermarket ring and pinion set. The kit comes with a 1-year limited warranty, and RANDYS Worldwide Automotive adheres to a return policy for most new, uninstalled items.
