Product Details

LuK GDK339B-MK is an axle differential bearing and seal kit engineered for professional repair work where worn bearings can create noise, looseness, or driveline instability. LuK states that each kit contains the OE-quality bearings needed for a proper transmission or differential repair, with components selected for the individual application rather than a one-size-fits-all approach. Compatible vehicle coverage includes 1967-2000 Jeep Wrangler, 1967-1996 Ford Bronco, and other classic truck and SUV platforms that use front or rear master differential kits.

This part cross-references SKF SDK339-BMK and Timken DRK339BMK for the same application. The GDK339B-MK part number is also useful when verifying service kit selection for Jeep Wrangler rear differential repair or Ford Bronco front differential service.

What It Helps Repair

• Differential bearing noise or growl
• Excessive bearing wear in the axle or differential assembly
• Loose or unstable differential operation
