Section 05-02H: Differential, Traction-Lok Limited Slip, 8.8-Inch Ring Gear | 1996 F-150 and Bronco Workshop Manual |
The limited slip axle assembly is identical to the conventional rear axle (4001) except for the differential (4026).
The limited slip differential employs two sets of differential clutch packs (4947) to control differential action. The mounting distance of the differential side gear (4236) is controlled by seven plates on each side: four steel, three friction, and one steel rear axle differential clutch shim (4A324). This steel rear axle differential clutch shim is of the selective type to control the position of the differential side gear.
The plates are stacked on the side gear hub and are housed in the differential case (4204). Also located in the differential case, between the differential side gears, is a differential clutch spring (4214), which applies an initial force to the differential clutch pack. Additional clutch capacity is delivered from the thrust loads of the differential side gear. Splined plates are splined to the side gear hubs which, in turn, are splined to the axle shaft (4234). The friction plate ears are keyed to the case so the differential clutch packs are always engaged.
