HMMWVs…
And
only
one
of ‘em
would be
wrong!
making your HMMWV tires
hold up for the long haul
takes lots of pm. So load
up on thse tire essentials!
Here’s
what you
operators
and
mechanics
need to
do to
keep the
wheels
turning
safely…
Steering Linkage
You may think you can skip an inspection or
lubing of the steering linkage every now and
then. But when a linkage part fails and someone
is injured or killed, you’ll find out just how
wrong you are!
A couple of inspections and a liberal lubing
every six months or 3,000 miles (whichever
comes first) is vital for keeping your HMMWV’s
steering linkage in good shape during normal
operations. You’ll need to up the number of
inspections and lubings when operating in mud,
snow or desert conditions, though.
Check idler arm for play
Check lower ball joint for play

my new
haircut?

Nine out of 10
drivers and
mechanics will
tell you the
biggest problem
they have with
HMMWVs is tires.
