Dodge 2008 Ram 2500 PowerWagon - Manual (Page 422)

WARNING!
Fluid level should be checked on a level surface and
with the engine off to prevent injury from moving
parts and to insure accurate fluid level reading. Do
not overfill. Use only manufacturers recommended
power steering fluid.
If necessary, add fluid to restore to the proper indicated
level. With a clean cloth, wipe any spilled fluid from all
surfaces. Refer to Fluids, Lubricants, and Genuine Parts
for correct fluid type.
Front Suspension Ball Joints
NOTE: When anticipating any severe offroad or hill
climbing maneuvers, the power steering fluid level may
be increased to the FULL HOT level (with a cold system).
In this way, the power steering system will continue to
provide assist as the inclination angle of the vehicle
increases, i.e. when the vehicle is not on level ground.
NOTE: When anticipating any severe offroad/dusty or
wet conditions, ensure that the outer tie rod ends are
properly greased before ans soon after the vehicle is
taken through such conditions. The greasing will help
purge contaminants and water from under the seal.
Regular greasing will prolong the life of the ball joints.
The ball joints and seals should be inspected whenever
the vehicle is serviced for other reasons.
The ball joints originally supplied with the vehicle are
permanently lubricated at the factory and do not require
service. However, if the seals on the ball joints are
damaged, the joints should be replaced. Serviceable
replacement ball joints are available.
