Steering Spindles; Control Arm Bushings; Front Brakes - Monaco Cayman 2005 Owner's Manual

The steering spindles attach to the front
axle and pivot on the kingpin. The wheel
end assembly and brake system attach to
the spindle. There are upper and lower
lubrication points for the kingpin. The drag
link attaches to the roadside spindle. After
initially lubricating the roadside and curb-
side kingpins, rotate the steering assembly
lock to lock (full left to right) then move
assembly back to center. This purges any
remaining air pockets. Continue lubricating
the kingpins until new grease purges with
no air pockets. Greasing interval is every
six months or 5,000 miles.
Control arms align the axles perpendicular with the frame. The panhard bar controls side to side
motion of the axles in the frame. Control arm bushings and panhard bar bushings do not require lubrica-
tion.
The M-100 series Sheppard steering gear requires no maintenance. Using hydraulic pressure to assist
rotating the output shaft of the steering gear provides power steering. Located at the end of the input
shaft of the steering gear is a poppet valve and worm drive. The poppet valve directs the hydraulic fluid
pressure to a type of spool. There are worm drive threads in the center of the spool. When in the center
position, pressurized hydraulic fluid bypasses the spool. When a turn is made, the poppet valve shifts to
one direction or the other, directing the hydraulic pressure to one side of the spool depending on turning
direction. The hydraulic fluid is then cooled before returning to the reservoir. Inspect for signs of leakage
when performing fluid level checks. Changing the hydraulic filter at regular intervals will help ensure
trouble free operation.
