You’ll also need to keep the
dampers
lubed
monthly
with
GAA. Without lube, the rod binds
and will soon bend like a pretzel.
You’ll fnd the lube point at the end
oF the damper rod.
The dampers are like mini shock absorbers that act as a stabilizer For the steering
system. Without ‘em, the steering column can give you a good shake down.
Rough
terrain,
rocks,
and
heavy brush can take a toll on
the damper rods. That’s why
you need to crawl under your
Stryker to visually inspect them,
especially aFter a mission over
rough terrain. Look For a bent or
broken rod or evidence oF oil on
the cylinder that could indicate
a leaking wiper seal. Report any
problems to your mechanic.
Cold Weather Problems
Extreme cold weather also has a negative effect on the steering dampers. Sustained
temperatures at or below 0°F result in a signi±cantly high number of steering damper
failures.
So, vehicles that are part of the 3rd Stryker Brigade in Alaska are now authorized to
remove the steering dampers when the temperature drops below 0°F for a sustained
period.
Removing the dampers may result in higher amounts of wheel kick and vibration
in the steering system, especially over rough terrain. That can result in increased wear
on steering components. So, inspect the steering system often for damage if you’ve
removed the dampers.
All drivers with vehicles that have had the dampers removed should receive a
precautionary brie±ng about the dangers of sudden steering movement and how best
to reduce it.
