TRAC-LOK Y DIFFERENTIAL DESCRIPTION In a standard differential, if one wheel spins, the opposite wheel will generate only as much torque as In the Trac-lok y differential, part of the ring gear torque is transmitted through clutch packs which OPERATION In operation, the Trac-lok y clutches are engaged by two concurrent forces. The first being the preload exerted through Belleville spring washers within the clutch packs. The second is the separating The Trac-lok y design provides the differential action needed for turning corners and for driving y differentials resist wheel spin on bumpy roads and provide more pulling power y operation is normal. In extreme cases of differences DIAGNOSIS AND TESTING GENERAL INFORMATION Axle bearing problem conditions are usually caused by: • Insufficient or incorrect lubricant. • Foreign matter/water contamination. • Incorrect bearing preload torque adjustment. • Incorrect backlash. of: • Insufficient lubrication. • Incorrect or contaminated lubricant. • Overloading (excessive engine torque) or exceed- ing vehicle weight capacity. • Incorrect clearance or backlash adjustment. of: • Severe overloading. • Insufficient lubricant. • Incorrect lubricant. • Improperly tightened components. • Differential housing bores not square to each other.
