Using your Pacbrake ball mount is easy. First, make sure your vehicle doesn't have a 3' hitch with an adapter to 2.5 or 2.0's as this mount won't fit. Attach the mount to your vehicle's hitch receiver and secure it with the standard 5/8' diameter hitch pin. Select the appropriate ball (2' or 2 5/16') for your trailer and adjust the height in 1' increments up to 6' as needed. Once you've connected the trailer, use the locking pin for added security. When it comes to maintenance, keep it clean and dry to prevent corrosion. Regularly check the locking mechanisms and pins to ensure they're in good working condition. If you notice any damage, contact PacBrake for warranty service.
