Special Tool Required Driver, 40 mm I.D. 07746-0030100 Check the carrier bearings for wear and rough rotation. If they rotate smoothly and their rollers show no signs of wear, the bearings are OK. Remove the carrier bearing (A) with a commercially-available bearing puller (B).

Install the new bearings (A) with the special tool and a press. Press each bearing on until it bottoms. There should be no clearance between the bearings and the carrier.
