Using our bearing remover, we installed the tapered roller bearing onto the pinion gear. Be sure to install the correct sized thrust washer, which should be measured and toleranced, as only the installer will know when he installs the gear set. Honda offers a shim kit that comes with an assortment of thrust washers to speed up the process (more on the thrust washer as we finalize the install). Tighten the locknut on the pinion drive while applying grease to the tapered roller bearing. Install the drive pinion and pinion spacer into the differential housing and tap it into place using a mallet. Install the oil seal then tighten down the locknut (14 lb-ft). Rotate the drive pinion a few times to ensure proper tapered roller bearing contact. If the drive pinion turning torque is within specs (see service manual) then tighten down to 210 lb-ft of torque.
