• Make sure that you are starting out with your trailer level from front to back. We recommend no more than around an inch of difference.

• If you were not the person that installed the WD Hitch originally, go through each of the steps in the manual and make sure your set up matches the installation instructions.
Also, make sure that when you set the brackets up in Step 4 of the manual that the chains are pretty tight (hand tight) before setting the brackets in place (this is more to give a good reference point for troubleshooting). The main thing here is to make sure that the top of the brackets are pulled back tightly (by hand) once the chain tension is maxed out.

•Do not try to get the tow vehicle perfectly level, it is NOT necessary – just make sure that you are not too extreme in either direction (see pictures in the manual for reference). 

• Is the tire pressure of each tire on your trailer and tow vehicle up to par? (Believe it or not this is quite critical and has fixed dozens of customer problems).

• Check your load. Is there too much weight in the trailer or tow vehicle? If not, perhaps the load is too far to the front or back of the trailer or tow vehicle and needs to be distributed better. Remember…it’s better to keep the weight shifted towards the front of the trailer than the back...approximately 60% in the front and 40% in the back.

• Ensure that the suspension of both the tow vehicle and trailer are in good working order, and adequate for your set up  Bad suspension can result in the Weight Distribution Hitch not being able to properly even your load (and can cause unwanted bounce).

• Follow the installation steps but this time try moving the Ball Housing up a notch (or two) in Step 2, and then try again.

NOTE: You should never have to 'mash' the red spring too far to get the unit to work properly.
