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.
