Installation Notes
- Verify shaft diameter. Measure your driveshaft diameter to confirm it matches the 30.00 mm inside diameter before installation.
- Check bracket dimensions. Confirm the bolt hole center distance of 109.00 mm aligns with your vehicle’s mounting points.
- Check alignment. Verify the driveshaft alignment before tightening the bracket bolts – misalignment will cause premature bearing failure.
- Replace as complete assembly. Do not attempt to press the bearing out of the bracket – replace the entire center support bearing unit.
- Professional installation recommended. Proper bearing alignment and torque specifications are critical to prevent premature wear and driveline issues.
