Steer Cylinder Removal
The steer cylinder can be removed from the steer axle for
overhaul or replacement without removing the steer axle
from the truck. The cylinder should be overhauled or
replaced if steering problems or troubleshooting informa-
tion indicate the cylinder is malfunctioning. See Group
2.5, Section 2, “Steering System Troubleshooting,” for
steering problem diagnoses. See Section 6 in this Group
for steer cylinder overhaul procedures.
1. Place a dram pan under the steer cylinder and remove
the hydraulic lines from the cylinder fittings. Cap fit-
tings and lines to prevent fluid from leaking and to
protect the components and hydraulic system from
dust and dirt. Label hoses and fittings for correct
reassembly.
2. Remove the snap ring from the bottom of the steering
link pin. Steering link pin attaches steer cylinder rod
end to steering link.
