Section 05-02H: Differential, Traction-Lok Limited Slip, 8.8-Inch Ring Gear | 1996 F-150 and Bronco Workshop Manual |
The pressure between differential clutch packs (4947) opposes differential action at all times. When the vehicle turns a corner, the differential clutch pack slips, allowing normal differential action to take place. Under adverse weather conditions, where one or both wheels may be on a low-traction surface such as snow, ice or mud, the friction between the clutch plates will transfer a portion of the usable torque to the wheel with the most traction. Thus, the wheel that is on ice or snow will have a tendency to operate with the opposite wheel in a combined driving effort.
CAUTION: Extended use of other than matching size spare tires on a Traction-Lok® rear axle (4001) could result in reduction in effectiveness (bias torque). This loss of effectiveness does not affect normal driving and should not be noticeable to the driver. However, extended usage will reduce the ability of the rear axle to provide added traction on slippery surfaces.
