Police and Taxi Vehicle Axle Maintenance
 Replace rear axle lubricant every 160,000 km (100,000 miles). Rear axle
lubricant change may be waived if the axle was filled with 75W140 synthetic
gear lubricant meeting Ford specification WSL-M2C192-A, part number FITZ-19580-B
or equivalent. Add four ounces of additive friction modifier C8AZ-19B546-A
(EST-M2C118-A) or equivalent for complete refill of Traction-Lok rear axles. The
axle lubricant should be changed anytime an axle has been submerged in
water.
450 and 550 Series Axle Maintenance
 Replace rear axle lubricant every 100,000 miles under normal driving conditions
on all 450 and 550 series applications. For 450 and 550 vehicles operated at or
near maximum Gross Vehicle Weights, the rear axle lubricant should be
replaced every 50,000 miles. In addition, this 50,000 mile schedule should be
observed when the vehicles are operated under the Special Operating Conditions,
where noted, beginning on page 37.
