SwayPro Troubleshooting
Issue: After coupling the trailer to the hitch head, the pickup squats and the front of the trailer dips.
Resolution: Turn the thumbscrew on the hitch head out one full turn. If the pickup has excessive squat and the trailer dips in front, make multiple turns of the thumbscrew. If necessary, raise the chains of the weight distributing bars up by one link.
Issue: After coupling the trailer to the hitch head, the pickup is level but the front of the trailer dips.
Resolution: Move the hitch ball up one notch. More pressure on the spring boards puts more pressure on the front. If the front of the trailer needs only minimal adjustment, raise the chains of the weight distributing bars up by one link. Otherwise, adjust the hitch mount receiver higher. Each adjustment up or down equals 1 ½”. Once the truck and trailer are level then everything is correct. To adjust the tow vehicle to a level position, increase the spring bar tension by dropping one link on the chain on each side of the hitch at a time until tow vehicle is level.
Issue: There is excessive sway.
Resolution: Excessive sway may indicate that the trailer is improperly loaded. As a guideline, the tongue weight should be 10-15 percent of gross trailer weight. If it is not, redistribute the weight accordingly. If you encounter continuous sway or swaying that does not dissipate quickly, adjust the load and the SwayPro. You may have to repeat adjusting the load and the SwayPro. You may have to repeat adjusting the load and the SwayPro until sway stops. To adjust the SwayPro, tighten the two hex bolts on the underside of the head assembly using a torque wrench. Tighten the hex bolts in 10 ft.lb. increments to a maximum of 100 ft.lbs. The bolts are torqued to 40 ft.lbs. at the factory.
Issue: The ride is excessively rough.
Resolution: Insure the weight distributing bars are level. And you have the correct spring bars. Springs that are too heavy (1000 lb bars with a 700 lb tongue weight) will cause the trailer to ride rough.
Issue: The head unit isn’t clearing the bottom of the tongue during tight turns and backing up.
Resolution: If the tongue of the trailer is 5” or wider, a hitch ball with a rise may be required. Also: If one leg comes loose and the other is tight, take bolt completely out and add a lock washer and then tighten to 55-60 lbs. Do this to both sides.
