14. Place an appropriately sized deep socket wrench (B) on the steering rack (C).
15. Set the steering gearbox in a press so the gearbox housing points upward, then press the cylinder end seal (D) and steering rack out of the gearbox. Hold the steering rack to keep it from falling when pressed clear. Be careful not to damage the inner surface of the cylinder housing with the tool.
16. Remove the cylinder end seal from the steering rack.
17. Carefully pry the piston seal ring (A) and O-ring (B) off the rack piston. Be careful not to damage the inside of the seal ring groove and piston edges when removing the seal ring.

20. Set the steering gearbox in a press so the gearbox housing points upward, then push out the cylinder end seal (D) 5-6 mm (0.20-0.24 in.) by pressing on the 24 "long 3/8" drive extension end.
21. Remove the steering gearbox from the press, and remove the washer from the gearbox inside.
22. Turn the special tool so it will fit through the rack guide hole of the steering gearbox, then position the special tool on the cylinder end seal (A). Make sure that the special tool is securely positioned on the seal edges.

23. Insert a 24 "long 3/8" drive extension (A), on the special tool. Place the steering gearbox in a press, then remove the cylinder end seal (B) from the gearbox by pressing on the 24 "long 3/8" drive extension.
Note these items when pressing the cylinder end seal:
- Keep the tool straight to avoid damaging the cylinder wall. Check the tool angle, and correct it if necessary, when removing the cylinder end seal.
- Use a press to remove the cylinder end seal. Do not try to remove the seal by striking the tool; striking the tool would break the cylinder end seal, and the seal would remain in the steering gearbox.

25. Separate the valve housing from the pinion shaft/valve using a press.
26. With your finger, check the inner wall of the valve housing where the seal ring slides. If there is a step in the wall, the housing is worn. Replace it.
NOTE: There may be sliding marks from the seal ring on the wall of the valve housing. Replace the valve housing only if the wall is stepped.
