5. Attach the trailer to the vehicle without the
weight distribution bars connected.
6. Measure the height from the top of the front
wheel opening on the fender to the ground;
this is height H2.
7. Install and adjust the tension in the weight
distributing bars per the manufacturer’s
recommendations so that the height of the
front fender is approximately (H2-H1)/2+H1
(about 1/2 the difference between H2 and H1
above Normal Ride Height [H1]).
8. Use the touchscreen radio settings and switch
off Tire/Jack mode. Make sure the truck
returns to Normal Ride Height. Perform a
visual inspection of the trailer and
weight-distributing hitch to confirm the
manufacturers’ recommendations have been
met.
9. The vehicle can now be driven.
