Driving Use extreme caution when accelerating or decelerating on slippery or unstable surfaces. Vehicles/axles equipped with traction differentials are inherently more sensitive to side-slip than vehicles equipped with conventional differentials. Stability can be retained if side-slip occurs by decelerating (letting off the accelerator). Do not apply the brake. To do so may result in loss of vehicle control. The vehicle's braking capacity is reduced when a turn is made while coasting downhill because the inside wheel is then disconnected from the driveline. Operating in low gear will allow the engine to act as a retarder and will improve braking capacity. Inspection and lubrication When servicing any driveline components on a vehicle equipped with a locking rear differential, ensure that the engine is off and all wheels are off the ground to prevent the vehicle from moving. Axles equipped with a locking rear differential deliver power to both wheels, even when only one wheel is on the ground. Failure to observe these cautionary measures may cause the vehicle to move which can result in property damage, personal injury, even death. This differential is designed to operate in the lubricant recommended by the vehicle/axle manufacturer; no special lubricant is needed. Refer to the Lubricant Specifications in your Owner's Guide for the proper axle lubricant. For very cold weather applications, use the lightest oil the axle manufacturer will allow to overcome possible sluggish reengagement of the driven clutch assemblies. No adjustments or alterations should be made to the differential. Refer to the vehicle/axle manufacturer's instructions for adjustments to other components in the axle. SAND INGESTION When driving through sand, traction or brake capability may be limited. Also, sand may enter your engine's air intake and severely damage your engine or your vehicle may stall. Driving through sand where the transmission vent tube or external breather kit is submerged may allow sand into the transmission and cause internal transmission damage. 20
