The clutch pilot bearing, a needle roller type, supports the transmission input shaft and is factory-greased. It should be inspected when clutch components are removed. If inaccessible or damaged, replace it. To remove, use a special puller from an auto parts store. Install a new bearing by lightly greasing the surface, ensuring the letter side faces the transmission, and hammer it into the recess. Reinstall all removed components and tighten fasteners to the recommended torque.
