Lubing
Follow the lubrication order completely. The number of
grease fittings on your tow pintle will vary depending on the
vehicle.
Lube them all, not just the ones that are handy or in plain
view. Miss a lube point and your pintle will come down
with a severe case of lockjaw!
The proper amount and type of lube that’s applied like
the LO says will go a long way toward keeping the pintle
ready to go when needed.
Keep the Dirt Out
If the tow pintle on your vehicle is covered in mud, dirt, corrosion or too much
paint, clean it or report it to your mechanic.
Pay special attention to the tow pin-
tle when driving your vehicle in dusty,
sandy conditions. Sand thrown up by
tracks or wheels will end up in the pin-
tle’s nooks and crannies. By the time
you get where you’re going, the pintle
is jammed full and impossible to open.
Avoid that problem by turning the
pintle upside down before you leave.
Gravity will help dirt and sand fall out
and keep the pintle clear.

Tow Pintle
Needs PM, Too
Sand gets
inside
pintle and
jams it up
But that’s what
you have to look
forward to if
you don’t apply a
little PM
now.
Lube all
grease
fittings!
gah!!
What’s
with this
tow pintle
anyway!?
it won’t
open!
That’s because
you
never
did
any PM on it!
Just gotta
hook 'em up
and we're
good to
go!
uh!
uh!!
mmph!
Few things are
more frustrating
than a tow pintle
that won’t open
or close when
you need it to.
