25-210121-1X Drive Shaft Center Support Bearing, New

Product Overview

25-210121-1X Drive Shaft Center Support Bearing is intended for center support service on selected 1710-series drive shaft assemblies. The support bearing carries the intermediate shaft section, while the rubber carrier helps isolate vibration and allows controlled movement as the driveline works under load. A worn support can contribute to thumping, vibration, rubber separation, bearing noise, or visible shaft movement.

This new independent aftermarket replacement is supplied for professional driveline repair. Its 20 support configuration must be compared with the removed unit because bracket geometry and bearing position affect shaft alignment.

Structured Product Data

Service and Fitment Guidance

Confirm the reference number, driveline series, bearing inside diameter, centerline height, bracket width, mounting-center distance, bolt-hole diameter, and rubber-carrier layout. Measure the removed support with the shaft unloaded and compare the bracket from the same orientation. Do not rely on vehicle year or series alone.

• Inspect the shaft tube, slip section, universal joints, fasteners, bearing journal, and mating surfaces before assembly.
• Keep the driveline phased and indexed as required by current service information; incorrect alignment can create vibration.
• Use proper bearing tools and torque procedures. Installation should be completed by a qualified driveline technician.
