What is the difference between a used, rebuilt and remanufactured differential?

differential inspection


Used differentials are generally removed from a junkyard vehicle and may not even receive a surface cleaning to remove outside road dirt. Used differentials are normally not disassembled, internally cleaned, or inspected. Used or junkyard components often have high mileage along with a poor history of maintenance – this can be a failure waiting to happen. Used or junkyard differentials may also come from a vehicle that was involved in an accident. In this case, the differential may have unseen damage.


Rebuilding is the reconditioning of components by cleaning, inspecting and replacing broken or severely worn parts. Rebuilt component quality can vary widely and many rebuilt products come with only a short term warranty.


Remanufacturing is to make as closely to new as possible. Components are carefully inspected, checked against original equipment measured specifications for correct dimensional tolerances and precisely remanufactured. Replacement parts are new or requalified to meet exacting standards and tolerances. It’s important to note that later model vehicles are very noise sensitive, so care must be taken when selecting a replacement differential for your application. Used and rebuilt differentials may not take this issue into consideration.

What is the warranty on a JASPER remanufactured differential?

Most JASPER Remanufactured Differential applications are covered by a 3 Year/100,000 mile (whichever occurs first) nationwide warranty – parts and labor. Ambulance, automotive off-highway use, package delivery, police, snow removal, taxi, tow truck, transit bus or any vehicle over 1 ton receive a warranty of 18 Months or 100,000 Miles, whichever occurs first.
