Section 05-02C: Axle, Traction-Lok Limited Slip Differential—8.8 Inch Ring Gear | 1993 Mustang Workshop Manual |
The pressure between clutch plates opposes differential action at all times. When the vehicle turns a corner the clutch 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 conventional spare tires on a Traction-Lok
rear axle 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 axle to
provide added traction on slippery surfaces.
