TRUCK SERVICE MANUAL
TM 5-4210-230-14&P-1
AXLE-FRONT
OPERATION
When the locking hubs are engaged in "4 x 4" and
transfer case is in 4W, full power is transmitted to both
wheels. When both front wheels are disengaged or in "4 x 2"
position and transfer case in 2W, shafts and differential will
remain idle, overcoming any unnecessary wear. For the first
320 km (200 miles) operate your new vehicle with the locking
hubs in "4 x 4" position to assist in initial break-in of the front
driving axle. Place transfer case control in 2wheel drive
position.
Fig.2. Dial Control
Always shift transfer case to 2H before attempting to
disengage the locking hubs.
DO NOT DRIVE unless controls on both hubs are set the
same!
To avoid excessive torque loads on the rear axle, DO NOT
drive vehicle in low range of transfer case with locking hubs
set in "4 x 2" position.

When reassembling the locking hub, lubricate as follows:
Lubricate dial, seal, splines, threads, ring and bearing with IH
251 HEP grease.
