SKF KRS143 Differential Crush Sleeve - Rear

SKF Differential Crush Sleeve KRS143

SKF KRS143 is a differential crush sleeve for rear driveline service, built to help set proper bearing preload during differential repair. It is used in applications such as Toyota 4Runner rear differential service and Toyota Pickup rear differential service where accurate load on drivetrain bearings is critical.

Key Features

• Bearing type: CRH SLV
• Supports correct drivetrain bearing load during differential setup
• Used in rear differential repair applications
• SKF part number KRS143 for service identification
• Cross-references Toyota 41231-24010 for the same application

Application Details

SKF KRS143 is a differential crush sleeve used in rear axle and differential service where pinion bearing preload must be set correctly. It is listed for 1988-1994 Toyota 4Runner rear, 1996-2000 Toyota 4Runner rear, and 1988-1994 Toyota Pickup rear. For Toyota 4Runner rear differential repair or Toyota Pickup rear axle service, KRS143 helps restore the bearing load specification required for a proper rebuild.

What It Helps Address

• Incorrect pinion bearing preload after differential teardown
• Noise from worn or improperly set rear differential bearings
• Premature bearing wear caused by reused crush sleeves
• Loss of setup accuracy during rear axle rebuilds
• Repeat repair work from inconsistent differential adjustment

Installation Notes

Replace the crush sleeve during differential service rather than reusing the old part. Measure and set pinion preload according to the vehicle service procedure, and verify bearing load after assembly. This part is used in rear differential applications for the listed Toyota 4Runner and Toyota Pickup models.
