What This Kit Helps Repair

• Rear differential bearing noise
• Excessive drivetrain vibration from worn bearings
• Rough or inconsistent differential operation
• Service needs during transmission or axle repair
• Wear-related bearing replacement on 7.5"/7.6" rear axles

Installation Notes

Confirm rear axle size before ordering, since this kit is listed for 7.5"/7.6" rear differential applications and one Isuzu Rodeo listing specifies 7.5" only. Professional installation is recommended for differential service because bearing setup and preload are critical to proper operation. This part cross-references SKF (e.g., SDK320-MK) for the same application.

Quality Assurance

LuK states that each differential bearing kit is assembled with OE-quality components selected for the specific transmission application. Part number GDK320-MK is built for professional repair use and is intended to match the bearing requirements of the listed driveline applications.
