Detailed Description

J8126500 is a Mopar differential bearing set intended for differential maintenance on compatible Jeep and Dodge vehicles. The fitment data shows separate applications for front and rear positions, including conventional differential front axle use and transfer case differential bearing service, depending on the vehicle and year. Because the same part number is used across several driveline configurations, confirming the exact year, model, position, and notes is important before installation. This part number, J8126500, is listed for Jeep Wrangler, Jeep Liberty, Jeep TJ, Jeep Cherokee, Jeep Grand Cherokee, Dodge Nitro, and Dodge Durango applications.

What It Helps Address

  • Noise from worn differential bearings
  • Excessive play in the differential assembly
  • Service needs after bearing or cup wear
  • Replacement of a damaged original bearing set
  • Driveline maintenance on listed Jeep and Dodge applications

Installation Notes

Verify the vehicle year, make, model, position, and fitment notes before installation. Some applications are listed with a 3.73 rear axle ratio and conventional differential front axle notes, while others are listed as transfer case differential bearing applications. Compare the original part number 05066048AA and the vehicle configuration to confirm the correct match.
