you need to start from scratch and do whatever the owners manual says to do. start with measuring the hitch hight on your trailer when you have it level on level ground. The you will need to adjust your ball to whatever the manual tells you to set it, eqaulizer you set it as close to the TT hitch hight as possible. equalizer uses washers to angle the head. Untill you have the ball set up right on your TV, you may continue to have problems. the spring bars should pull your trucks back end (and TT front end) back up to about where it was when it was unhitched and level but loaded, and when you stand back and look at the setup, both TT and TV should be relatively level and loaded. The WDH conteracts the TT toungue weight and keeps the TV level thus keeping weight on the front axle and prevents getting a light or bouncey unsafe ride.
I hope that helps explain what your goal is.
