What is included
Reference Q820-330000-10000 suits CFORCE 450, 450L, 450S (CF400ATR, CF400AU, CF400AZ chassis codes), CFORCE 500, CForce 520, CForce 520L, CForce 550 (CF500ATR, CF500AU, CF500AZ chassis codes), CFORCE 600, CForce 625, CForce 625 Touring (CF600ATR, CF600AU, CF600AZ chassis codes).

Wear and fault symptoms
- Whining, howling noise that varies with speed – worn differential carrier bearings or worn, incorrectly meshed ring and pinion gears
- Grinding or growling noise, worse in turns – failing carrier or axle bearing, advanced gear tooth damage
- Clunk when shifting direction or on/off throttle – excessive gear backlash, internal play
- Gear oil leaking at axle seals, pinion seal or housing cover gasket
- Water, mud ingress after deep-water crossings, contaminating the gear oil (emulsified or milky oil)
- Metal particles, debris collected on the magnetic drain plug (0180-332100)
Similar symptoms can come from neighbouring components, so inspect and test before replacing the part.
If differential fluid leak appears after a load change, the phasing and balance of the driveline should be re-verified on a lift.
