Axle Shaft End Play

Axle shaft end play is allowable up to 0.762mm (0.030 inch), but can be as low as 0.127mm (0.005 inch). It is controlled by the u-washer (4N237) that holds the axle shaft (4234) in the pocket of the differential side gear (4236). To reduce clearance, replace differential side gears, Traction-Lok® clutch plates if equipped, differential side gear thrust washers (4228) or axle shafts as required.

F-150 and BroncoAll8.8-Inch Ring Gear5.50b4.582.60

a All conventional and Traction-Lok® axles use Premium Rear Axle Lubricant, XY-80W90-QL or -KL or equivalent meeting Ford specification WSP-M2C197-A plus 4 ounces of Ford Friction Modifier F3TZ-19B546-MA or equivalent meeting Ford specification WSP-M2C196-A for complete refill of Traction-Lok® rear axles.
b Lubricant levels are determined by filling the axle 6.4-14.2mm (1/4 to 9/16 inch) below the bottom of the filler hole with vehicle in a level position.

Note: Rear axle lube quantities must be replaced every 160,000 km (100,000 miles) or if the axle has been submerged in water. Otherwise, the lube should not be checked or changed unless a leak is suspected or repair required.
