The Differential Division of JASPER Engines & Transmissions tackles the job of remanufacturing the Jeep Grand Cherokee independent front suspension differential from model years 2005 and up.

Prior to 2005, Dana Corporation was the main source of drivetrain components in many Jeep products. In 2005, Jeep made a design change from a solid front axle to an independent front suspension.  

“Jeep uses two hefty snap rings to adjust carrier bearing pre-load and backlash”, says Wayne Mehringer, JASPER Differential Division manager.  The snap ring in Figure 1 measured .174 thick!  It requires a modified pair of retaining ring pliers to keep the ring compressed for installation. “A pinion depth shim located under the pinion bearing cup is also much thicker than the ones used in previous applications, said Mehringer.” The shim in Figure 2 measured .213 thick.

In order to properly adjust this version of the Jeep Grand Cherokee front differential, JASPER keeps in stock 98 different-sized snap rings and 75 different-sized pinion depth shims.  Each component varies in thickness in .001 increments. “JASPER must keep these components in stock to properly set these units to original equipment specifications,” added Mehringer.

So when a Grand Cherokee comes to your shop needing an independent front suspension differential, give JASPER a call. Each differential is covered by JASPER’s 3-Year/100,000 mile nationwide transferable parts and labor warranty. Full warranty disclosure is available on our website or upon request.
