Note: Box does not have to be removed from truck to replace lower seals, although it is much easier off the truck. By removing the box one does not have to deal with the fan shroud, can fully drain the box, and can replace the needle bearing along the sector shaft.

Wire your steering wheel to the seats to prevent it from turning. Your steering wheel can turn freely in any direction and ruin the air bag ribbon wire if you do not tie it down.

Disconnect the intermediate shaft. If have a Borgeson shaft you must loosen the allen(metric) on the locking slider in the middle of the shaft. You may have to use a punch and mallet to tap the shaft off the input shaft of the steering box.

Place a drip pan below the steering box and use a 18mm open end wrench or crows foot to loosen the high and low pressure lines coming from the steering pump.

Once loose pull the lines across the frame rail and let them drain the pump down into the drip pan. Now loosen the three bolts on the opposite side of the frame as the box to take the box down. Loosen two of them completely leaving one to hold the box firmly in place. THE BOX IS HEAVY. You may want to get a buddy to help you loosen the last bolt as you hold the box (almost 40 lbs with fluid.)

When dropping the box down turn it over to drain any excess fluid out of the hose line holes. Place the box upright in a vice using pipe clamp jaws if you have a set.

Place drip pan below sector shaft with box in vice and loosen the 4 bolts on the top plate. With all four bolts removed pull straight up on the plate to remove the plate and sector shaft. When you do this a lot of fluid will come out of the lower seal area.
