How to replace the front and rear seals of the transfer case on Toyota T100?

This procedure applies to both the front and rear seals of the transfer case. It is not necessary to remove the transfer case to replace a seal. To begin, raise the vehicle and support it securely on jackstands. If replacing the front Transfer Case Seal, remove the front driveshaft; if replacing the rear seal, remove the rear driveshaft. Unstake and remove the companion flange retaining nut, then remove the companion flange. If the flange is difficult to remove, use a puller. Pry out the seal with a screwdriver or seal removal tool, being careful not to damage the seal bore. Lubricate the new seal lips with petroleum jelly and drive the seal into place with a large socket or seal installer tool. There is also a smaller seal inside the companion flange that may need to be replaced. The remainder of the installation is the reverse of removal, making sure to tighten the companion flange nut.
