Locking Differentials - Traction-LOK: Description
CHANGES, CAUTIONS, CORRECTIONS
LIMITED SLIP & TRACTION-LOK CLUTCH SLIPPAGE NOTE: When encountering complaints of clutch plate chatter, it is recommended vehicle be driven in tight circles; 5 circles clockwise and 5 circles counterclockwise to verify clutch chatter. If verified, siphon all lubricant from rear axle. Refill with ESW-M2C119-A lubricant and repeat test, chatter should disappear.
Traction-Lok (torque sensitive) locking differential employs a multiple disc clutch to control differential action. Shim(s), which control side gear mounting distance, four steel, four friction and one composite plate (steel on one side and friction material on the other) stacked on a clutch hub, and four ear guides are housed in the differential cover. Located in differential case between side gears is a one piece pre-load plate and block (four pinion) and four calibrated pre-load springs, which apply an initial force to clutch pack. Additional clutch capacity is derived from side gear thrust loads. The four friction plates are splined to clutch hub, which in turn is splined to left axle shaft, and the eared steel plates are dogged to the case.
