Removal Procedure
1. Siphon the power steering fluid from the fluid reser-
voir.
2. Raise and suitably support the vehicle.
3. Disconnect the power steering gear hydraulic cylin-
der pipes from the power steering gear at the valve
end. Replace the O–ring seals as needed.
4. Disconnect the power steering gear hydraulic cylin-
der pipes from the power steering gear at the cylin-
der end.

from the vehicle.
Installation Procedure
1. Lubricate any new O–ring seals with power steering
fluid.
2. Place the O–ring seals into the housing and install
the steering gear hydraulic cylinder pipes.
3. Connect the power steering gear hydraulic cylinder
pipes to the power steering gear at the valve end.
Tighten
Tighten the hydraulic cylinder line fittings at the valve
end to 18 NSm (13 lb–ft).
