Place a tag on hoses for identification and correct
assembly. Be prepared to collect the hydraulic oil as you
remove steering lines. Slowly loosen the hydraulic
hoses to release any remaining pressure. Install plugs in
the hose ends and caps in the cylinder ports.
Loosen the hex nut (8, Figure 10-25) on one of the
cylinder tie rod ends (12) until none of the threads on the
tie rod are exposed. Using a hammer and a tie rod fork,
remove the tie rod from the swivel housing.
Mark the tie rod for identification during assembly.
Remove the tie rod (12) from the cylinder rod. Be careful
not to tamper with the length of the tie rod assembly. If
measurement is changed, the axle will have to be
checked for toe-in.
