JASPER® remanufactures a complete line of Rear Axle Assemblies and Differentials including Dana, Chrysler, Spicer, Ford, and GM. Most popular chassis applications are available for immediate exchange. Toyota and other manufacturer's differentials are available with one day in-plant custom remanufacturing.
When it comes to remanufacturing differentials and rear axle assemblies, JASPER® sets the standard, adhering to the measured standards of the original equipment manufacturer. Our state-of-the-art reman processes allow us to remain firmly on the cutting edge when it comes to remanufactured differentials. Factory and distributor inventories together with a substantial stock of parts, allow us to provide overnight availability on over 500 models and ratios. Used or junkyard components may have high mileage and a poor maintenance history – a failure waiting to happen. Many used or junkyard components come from a vehicle that was involved in an accident and may have unseen damage. Their process is quite precise.
STEP ONE THOROUGH CLEANING
- Pre-wash
- Complete disassembly
- Thorough cleaning
- Rust stripper
- Rinse
- Final wash
- Buffing
COMPLETE INSPECTION
- Critical inspection is given to all areas of housing and gear assemblies.
- Inner pinion bearing bore inspection for spin damage, typical of a lubricant-related failure, and miking for conformance to dimensional tolerances.
- Miking and visual inspection of the axle end, as well as inner and outer wheel bearing and wheel seal surfaces, for wear and damage.
- Gear inspection at multiple points throughout the remanufacturing process.
- Inspection of carrier and pilot bearing bores for correct size and roundness to avoid premature bearing failure.
ALL NEW PARTS PROVIDED
- Bearings
- Gaskets
- O-rings
- Seals
- Thrust washers
ASSEMBLY BY HAND WITH MULTIPLE TESTS
- Pinion bearings are preloaded to specifications.
- All gears are lubricated.
- Ring and pinion are replaced only in matched sets.
- Torquing of all bolts to O.E.M. specifications.
TESTING THOROUGHLY
- Precise measurement of runout as applicable to differential design due to its influence on adjustments to backlash and the tooth contact pattern. JASPER limits runout to .008 of an inch, with some units requiring specifications as close as .003 of an inch.
- Inspection for correct backlash clearance to assure proper gear lubrication for reduced noise and to avoid overheating, especially in severe-duty applications.
- Exact adjustments of tooth contact pattern, within thousandths, for minimum gear noise and reduced fatigue. The contact pattern must meet O.E.M. drive and coast-side requirements.
- Gauge block inspection assures correct dimensional tolerances in order to reduce gear noise
To rebuild is to recondition by cleaning, inspecting and replacing severely worn or broken parts. Serviceable parts are reused within the manufacturer's acceptable wear limits. The quality of rebuilt components varies widely and many come with only a limited warranty.
