Technical Specs / Installation Tips

Which size do I need?	4-cyl: 168 mm 6-cyl: 188 mm 8-cyl: 210 mm
Confirm fitment	Use our video guide to check via VIN on BMWFans.info and confirm your exact differential type/size.
Noise diagnosis tip	During a safe drive, gently weave left/right (like warming tires). If noise changes, suspect a wheel bearing. If noise stays constant, the differential bearings likely need replacement.
Backlash target	0.08–0.12 mm on most BMW ring-and-pinion sets (verify at multiple positions with a dial indicator).
Included in the set	1× Crush sleeve 1× Small pinion bearing 1× Large pinion bearing 2× Side bearings 1× Input flange oil seal 2× Output flange oil seals 2× Side-cap O-ring seals
Setup note	Use correct shims to set carrier preload/backlash and verify gear-contact pattern with marking compound.
