The Mack CRD92R573 is a CRD92 front differential with a 5.73 ratio. A few details decide whether it fits your axle: fine or coarse spline on the input and output shafts, one tapered ball stud hole or a two bolt dog bone style upper torque rod, whether the rear of the differential housing has four bolt holes for a transverse rod mounting plate, and your axle spline count.
On a differential like this, a howl or whine under power usually points to worn gearing, and a whir when you lift off the throttle to the pinion bearings. It is sold exchange by Pro Gear and Transmission. Call us with your numbers and we will confirm fit.
A refundable core charge of $1,500.00 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.
