Each of Jasper’s remanufactured differentials undergoes an extensive "Do It Right" process that ensures worry-free operation. This includes:

• Disassembly and thorough cleaning of the differential housing.

• Critical inspection of all areas of the housing, along with gear inspection at multiple points throughout the remanufacturing process.

• Installation of new parts, including bearings, gaskets, O-rings, seals, and thrust washers.

• Pinion bearings are preloaded to specifications, with ring and pinion gears replaced only in matched sets.

• Precise measurement of runout, along with inspection for correct backlash clearance and exact adjustments of tooth contact pattern.

• Four quarts of 75W-140 synthetic gear oil included.

The Dana M300 differential is covered by a nationwide, transferable, warranty of up to 3 years/100,000 miles parts and labor. Full warranty disclosure is available on the company website, or upon request.
