FRONT AXLE - Continued
Loosen pinion yoke nut (12), but do not remove. A force in excess of 1000 ft lb (1360 Nm) may be required
to loosen nut.
Accidents causing serious or fatal injuries may occur unless the truck is supported by maintenance
trestles. Never rely on hydraulic jacks or mechanical lifting devices for support.
Lift front end of truck and place maintenance trestles under both ends of axle housing. Be sure trestles are
positioned under axle housing and not wheel ends.
Remove differential lock air shift unit as detailed in TM 5-4210-220-12.
Disconnect tie rod end (6) and steering drag link from left wheel end (see TM 5-4210-220-12).
Support left-hand wheel using a wheel lift truck. Remove capscrews (1) and nuts (2) attaching wheel end
(axle ball) (3) to axle housing (4). Pull wheel and wheel end away from axle housing sufficiently to disengage
axle shaft (5) from differential. Remove brake air lines if necessary.
Repeat step 5 for the right-hand wheel and wheel end.
Push shift fork (7) to the side, away from differential, to engage sliding clutch. This clutch must be engaged
in order to permit removal of carrier from housing.
Serious injuries may be sustained unless safe work practices are maintained. Do not lie under differential
carrier after attaching hardware is removed. Use a suitable jack to support and remove carrier assembly.
Place a transmission jack under differential housing and remove capscrews (8), nuts (9), and vent line (10).
Pull differential carrier assembly (11) free and remove from axle housing (4).
Before installing differential carrier in axle housing, inspect and thoroughly clean interior of axle housing.
