Rick,
I don't see where you posted that after changing the HCVs that the ride height was readjusted to proper ride height.  May just be an omission or I missed it in your posting.  If not the coach ride height needs readjustment to the 12" measurement---front & rear, left & right.

Also when the HCVs were installed, did you test to make sure that they were working properly---raising the rod should cause the coach to rise, lowering the ride should make the coach lower.  If this step was not done, you could have gotten a bad HCV or have the rod installed wrong. I have had bad new HCVs.

Good luck.........................
