the hitch is an older model(20 yrs or so) where the weight bars slide on the top of the trailer A frame for sway control. we've done almost 50,000 km on this tow combination with no issues except the leveling.
Can you post a photo of the hitch?
I've never seen a WDH which has weight bars which slide on the top of the frame. Seems as though that would make it very hard to adjust.
Does the WDH have a ball mount which can be adjusted for rearward tilt? If so, perhaps the ball mount has slipped so that it is no longer tilted enough to load the WD bars?
