TIE ROD REPLACEMENT — R, G,
P20, AND P30 MODELS EXCEPT
MOTORHOME
There are two tie rod assemblies, one attached to each
end of the relay rod. Each assembly consists of an adjuster
tube, two clamps and two tie rod ends. The ends are
threaded into the sleeve and secured with the clamps.
Right and left hand threads are used for toe-in adjustments
and steering gear centering. The tie rod ends should be
replaced when excessive up-and-down motion is present,
or when excessive end play or loss of motion at the ball
stud exists.
Before servicing, note the position of the tie rod adjuster
tube and the direction from which the bolts are installed.
The tie rod adjuster tube components may be rusted. If the
torque required to remove the nut from the bolt exceeds 9
N*m (7 ft. lbs.) discard the nuts and bolts. Apply penetrating
oil between the clamp and tube and rotate the clamps until
they move freely.
m Important
• Do not attempt to free the ball stud by using a pickle
fork or wedge-type tool, because seal or bushing
damage could result (figure 6). Use the proper tool to
separate all ball joints.
