If the ride height at the front dropped - especially as much as 1.5" - from the unloaded position when the trailer was attached and WD applied, the WD hitch was not adjusted properly. It was adjusted to apply far too much load transfer, according to the instructions from Reese and other WD manufacturers: the WD system should just bring the front back down to the unloaded position, not further down.
Compared to heights of wheel wells on Trailblazer without trailer. Per the instructions from my Reese 66151 -
"Re-measure the front wheel well reference point. Front wheel well height
MUST be equal to or less than the original measurement. If the front wheel well height is higher
than previously measured, the head tilt angle must be increased (tilted downward). If the front
wheel well height is substantially lower than originally measured (1 ˝ inches or more) the head tilt wheel well height is substantially lower than originally measured (1 ˝ inches or more), the head tilt
angle must be reduced (tilted upward), or for coarse adjustment the pad hanger bolts can be lowered
one hole. Spring bars must be unloaded and removed from the pad hangers prior to adjusting head
tilt angle or removal of shoulder bolts. If head angle or shoulder bolt location adjustments are made
repeat hook up steps until the front wheel well height is equal to or less than originally measured.
It’s preferred that the rear of the vehicle settle the same amount or more than the front.
• Optional: The ideal setup would allow the vehicle to settle an equal amount (front and rear) from the original measurements.
The mechanics of the Anderson are of course different, but the end measurements should be similar. (I did make sure the rear drop was slightly more than the front.)
