The Mack Rear-Rear Air Posi Traction Differential CRD151 5.04 Ratio or CRD151R504 is a rear-rear drive axle differential with a 5.04 ratio. A differential splits driveline torque so each wheel on the axle can turn at its own speed through a corner while both keep driving. When one is wearing out, unusual noise, extra heat or scrubbed tires are the usual clues.
To get the right unit, tell us whether your pinion is fine or coarse spline, whether the upper torque rod mounts to one tapered hole or two bolt holes, whether the back of the differential housing has bolts for a transverse rod mount, and your axle spline count (count the teeth on the axle shaft). This is a genuine Mack part from Pro Gear and Transmission.
A refundable core charge of $2,500.00 applies to this item and will be collected at checkout. The core charge is refunded upon receipt of your returned core, subject to its condition; customer is responsible for return shipping. Call us at (877) 776-4600 for details.
