Yukon Jeep CJ Dana 30 Front Axle Bearing & Seal Kit
YUKAK F-J01
The Yukon Axle Bearing and Seal Kit is designed to restore proper wheel-end support and sealing performance in Jeep Dana 30 standard rotation front axle applications. Built with high-quality Timken bearings, races, and wheel seals, this complete service kit helps eliminate wheel-end play, reduce bearing noise, and prevent contamination caused by worn or damaged axle components.
Dana 30 front axles found in Jeep CJ applications are subjected to constant steering load, off-road abuse, and water or mud contamination that can wear out wheel bearings and seals over time. Designed to service one side of the axle, this kit is ideal for Jeep restorations, trail rigs, and daily-driven classic CJ platforms.

Tech Insight
Dana 30 front axles use tapered wheel bearings that support both steering load and vehicle weight. In off-road conditions, mud, water, and oversized tires can accelerate bearing wear and compromise wheel seals, leading to steering looseness and premature hub wear.
Replacing bearings, races, and seals together helps ensure proper wheel bearing preload and long-term durability. During installation, inspect the spindle and hub surfaces for wear or scoring that could shorten bearing life or affect wheel seal performance.
