Considerations (continued)

• Clunk - Most drivelines may produce a “clunk” due to the driveline’s inherent backlash

when stepping on and of the gas. The Powertrax No-Slip Traction System may

make this characteristic more prominent in some vehicles. Standard shift ve-

hicles usually exhibit this condition more than automatic shift vehicles.

• Side-Slip - Use extreme caution when accelerating or decelerating on slippery or un-

stable surfaces. Vehicles equipped with traction adding differentials are inher-

ently more sensitive to side-slip than vehicles equipped with conventional

differentials. Stability can be improved if side-slip occurs by decelerating.

***Caution: Do not apply the brake or brake very carefully if necessary using

extreme caution. Loss of vehicle control may result.

• Driveline Windup - When a vehicle turns, each wheel follows a slightly different path

causing each wheel to turn at a slightly different rate. In many “selectable”

4-wheel drive vehicles that have no compensating “center transfer cases”, en-

gaging the front axles will cause the wheels to try to “slip” a little as the vehicle

is turning to equalize differences in wheel rotations. On poor traction surfaces,

such as dirt, etc., this action occurs relatively unnoticed. However, hard trac-

tion surfaces fight the driveline’s attempt to equalize. As a result, the driveline

can become highly stressed and may bind up or even break. Manufactur-

ers of these type of vehicles require that the vehicle not be driven on hard

surfaces in 4-wheel drive mode with the front axles engaged. Full-time 4-wheel

drive vehicles and “selectable” 4-wheel drive vehicles with compensating “cen-

ter differentials” mitigate this condition. Using the Powertrax No-Slip Traction

System in these vehicles will not reduce driveline windup. The vehicle owner

must conform to the operation recommendations of the vehicle manufacturer.
