What It Helps Solve

• Rear differential bearing noise
• Seal leakage at the axle or differential assembly
• Wear in bearing and cup/cone components
• Service needs on 9.00-inch 28-spline rear axle setups
• Incomplete repairs caused by replacing only one wear item

Installation Notes and Tips

Verify axle housing, spline count, ring gear notes, and rear position before installation. Confirm the bearing type and dimensions against the original components, especially on 1957-1970 Ford Thunderbird, 1960-1970 Ford F-100, 1965-1970 Ford Mustang, and other listed rear applications. Proper setup of bearing preload, gear pattern, and seal seating is important for a successful differential service.

Quality Assurance

SKF manufactures this kit to high quality standards and states that its differential service kits are built to meet or exceed original equipment specifications. The included seals use SKF’s Bore-Tite coating, and the bearing components are supplied as matched sets for consistent service results.
