After installing the new bearings on the transfer driven gear using the proper tools, apply 1g of grease (Nichimoly N130 or Conoco-Phillips Multiplex Red #2 grease) on the roller bearings as shown in the photos. Install the gear assembly into the transfer case and rotate the shaft to spread the grease throughout the front bearing rollers evenly. Repeat the procedure for the rear bearing in the extension housing. Follow the remaining procedures as outlined in the applicable service manual.

Apply grease between all of the rollers. Once installed, rotate the shaft to spread the grease.
