THREADED NUT MAINTENANCE
In addition to the routine maintenance that should be
done to your coupler and hitch, this guide outlines
how to best replace the threaded nut underneath
your coupler to promote safe towing conditions.
CHECKING THE NUT
It’s important to check your threaded nut, or locknut,
on a routine basis but at least once a year or before
long trips. You want to ensure that the threaded nut is
secure, not damaged, and tight enough.
When you lower the coupler latch to lock onto your
vehicle’s 2” ball, you should just barely be able to
wiggle the handle in its locked position. This indicates
the hitch coupler has a snug fit over the 2” ball. If the
latch does not go down easily, the nut may be too
tight and we recommend loosening the nut a
quarter turn.
WHAT YOU’LL NEED
• Threaded nylon nut
• Drive ratchet
• 3/4” socket
REPLACING THE NYLON LOCKNUT
You will use this guide to remove the locknut, or nut,
that holds the bolt which secures the coupler latch in
place. You’ll then replace it with a new nut.
Which size nut you need to will depend on which
generation of axle you have. To determine which
nut will fit your camper, remove the current nut and
compare it to the image on the right.
REPLACEMENT PROCESS AND TIPS
First, open the coupler latch then use a drive ratchet
to remove the original nut from the coupler.
Leave the latch open and move the new nut in place.
Using the 3/4” socket, tighten the nut into the bolt
that is secured to the open coupler. You want to
ensure this piece is securely in place, but don’t
overdo it by forcing it too tight as it can
damage the nut.
As always, the Support team is available to help
answer any questions you have about this process.
