How to Install an RV Sway Bar

A sway bar controls the trailer.

Sway bars increase the stability of the trailer being towed behind a truck or van. This means on a windy day or in an open field the trailer will not swing uncontrollably behind the vehicle. It not only increases the stability of the trailer, but also it increases the safety to yourself and others. A sway bar can be installed by most handy people.

Things You'll Need

• Grease
• Drill
• 3/8 inch bit
• Torque wrench
• Hammer

Instructions

1. Attach the sway control ball 1 3/8 inch forward on the hitch ball and 5 1/2 inch outward.

2. Install the ball using a lock washer and nut.

3. Position the ball mount so the hitch bar is on the center line. Check the position of the nylon pad.

4. Install the handle with the washer into the body.

5. Lubricate the handle threads, washer and handle flange with the grease.

6. Position the slide bar end 4 1/2 inches from and parallel to the body. Tighten the handle.

7. Put the slide bar coupler on the ball. Hold the bracket up to the frame.

8. Position the bracket for the best handle clearance.

9. Rivet the four corner holes to secure the frame clamp bracket to the frame.

10. Drill a 3/8 inch hole through the bracket and frame side. Install the drive rivet.

11. Drive the rivet pin flush with the rivet head using a hammer.

12. Drill the three remaining corner holes.

13. Install the rivet or bolt. Check for interference.
