front axle
While driving the motorhome, be aware of
any changes in the feel of steering and have
the system checked when noting apparent
differences. It is normal to hear some hydraulic
noise from the steering, especially when the
steering is at maximum, or while turning
the wheel when the motorhome is parked.
Investigate any unusual or loud noises that
occur. Begin by checking the level of the
hydraulic fluid. Traveling at slow speeds over
rough surfaces may cause a “clunking” noise
to emanate from the steering column, but
if noise is heard on smooth surfaces while
sharply turning back and forth, the noise
should be inspected and repaired as necessary.
Shimmy and looseness should be checked
and corrected as soon as possible. If looseness
is felt in the steering, the steering linkages can
be observed while someone turns the steering
wheel left and right. Watch the linkages for
evident play or uneven interaction between
components to help pinpoint a problem. Have
the steering system checked for damage after a
severe impact, such as striking large potholes
or curbs, and front-end collisions. Observe
the alignment of the steering wheel; a change
in the alignment may indicate damage to the
steering components or suspension.
Maintenance for the system entails adequate
lubrication. Use only a hand operated grease
gun on the fittings. Grease fittings for the
steering system are found on the both ends of
the drag link (the bar connecting the steering
gear to the axle), and on the intermediate
steering shaft located between the steering
wheel and steering gear.
Correct front end alignment promotes
longer tire wear and ease of handling while
minimizing effort on the steering system and
the axle components. Use NLGI #2 Lithium
soap base lubricant for all steering linkage and
brake components.
Wheel Bearings
The front wheel bearings utilize an oil bath
(wet hub) system. The hubs are filled with
SAE 90w. Maintenance consists of oil level
checks before each trip and every 1,000 miles.
Change the oil yearly or every 30,000 miles
Inspect the wheel bearings for wear any time
that the hubs are removed from the front axle.
INSPECT:
The oil level before each trip or every
1,000 miles.
Front Axle Lubrication Level:
Inspect the level of lubricant when the
vehicle has been at rest for ½ hour to ensure
accurate lubricant indications. The level should
be maintained within .25 inch (¼”) of the
center fill plug on the hub, as shown. The hub
has both a fill plug (rubber plug in the center
of the hub), as well as a drain plug mounted to
the side of the hub. To add lubricant, pry the
center fill plug from the hub and add lubricant.
When finished, push the plug firmly into place,
ensuring that it is evenly seated.
Lubricant Replacement:
Position hub so the drain plug is at the
bottom. Remove the plug using an Allen
wrench. Allow lubricant to drain. Replace
drain plug. Remove fill plug. Fill hub with
SAE 90w. Install fill plug. Road test then
recheck level. Adjust level as necessary.
