WARNING
Do not place yourself under motorhome
without first properly blocking frame
(jackstands) from coming down in case
of rapid deflation of air system.
Greasing the Intermediate Steering
Shaft Universal Joints:
1.
Check the shaft for looseness. Repair if
loose or worn.
2.
Apply the specified grease at the grease
fitting on the universal joint. Apply
until the new grease purges from all the
seals.
3.
If the new grease does not purge from
the seals, disassemble and clean the
joint or replace the universal joint.
DO
NOT
lose the needle bearings.
Greasing the Intermediate Steering Shaft
Slip Yoke and Splines:
1.
Check the shaft for looseness. Repair if
loose or worn.
2.
With finger, cover the rear air hole so
grease flows to the front seal. Apply the
specified grease at the grease fitting on
the slip yoke. Apply until new grease
purges and forces finger away from
the air hole in the end of the slip yoke.
Greasing interval is yearly or every
30,000 miles.
NOTE
Depending upon application universal
joints may have two grease fittings each.
It is necessary to apply grease to each
fitting to properly lube the universal
joint.
Drag Link
The drag link connects the steering box
pitman arm to the steer axle. The movable joint
(ball joint) uses sealed boots to prevent water
intrusion.
DO NOT
rupture the boot when
applying grease. Grease interval is six months or
every 5,000 miles.
NOTE
It will be necessary to start the
motorhome and turn the steering wheel
to access fitting(s).
Center Link
The center link is located on the backside of
the steer axle. The center link attaches the two
wheels together causing the right front to track
with the left front. Greasing interval is every six
months or 5,000 miles.
Steering Spindles
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 curbside 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 Arm Bushings
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 lubrication.
Intermediate Steering Shaft: Torque clamp
bolt to 48 ft. lbs. for 3/8” and 75 ft. lbs. for
7/16”.
