Description And Operation: Description

WARNING: This page is about a different car, the 2003 Ford RV Cutaway, 2003 Ford Econoline, 2003 Ford E550 Super Duty, 2003 Ford E450 Super Duty, and 2003 Ford Cutaway. However, it is still accessible from the selected car via links, so may be relevant.

The Traction-Lok® rear axle assembly, except for the differential case (4204) and its internal components, is identical to the conventional rear axle (4001). The Traction-Lok® differential (4026) employs two multi-disc differential clutch packs (4947) to control differential action. The mounting distance of the differential side gear (4236) is controlled by eight plates on each side: four steel and four friction. Also included is one steel selective shim to control the position of the differential side gear (shim selection may determine that two select shims be used), and one Belleville spring plate which, because of its slight concave design, provides initial preload to the differential clutch pack. Additional clutch pack capacity is delivered from the thrust loads of the differential side gear. Steel clutch plates are splined to the side gear hub which, in turn, is splined into the axle shaft (4234). Tabs on the friction plates are captured in the case by matching slots, thus providing continuous engagement of the differential clutch packs.
