What It Helps Address

• Excessive play or looseness in the differential pinion support area
• Noise caused by worn bearing surfaces during driveline rotation
• Friction and heat buildup from degraded bearing contact
• Uneven pinion support that can affect driveline stability
• Service replacement needs on Chrysler axle and New Process 4500/4500HD applications

Installation Notes

Verify the bearing dimensions and axle or transmission configuration before installation. This part is used across rear inner Chrysler axle applications and select New Process 4500 / 4500HD transmission setups, so matching the vehicle’s exact driveline specification is essential. For best results, inspect related driveline components for wear before reassembly.
