It seals the differential carrier to prevent gear oil leaks at the pinion yoke, maintaining proper lubrication and preventing dirt intrusion. You’d replace it when you see oil seepage around the pinion flange, during a differential rebuild, or if loss of gear oil leads to noise or potential bearing failure. It fits common Meritor 145, 16X, and 18X series axles often found in line-haul and vocational trucks.
