Yep, ride height valve... If a broke sway bar, sometimes the ride arm height valve will slide out of the slot, when going thru a front suspension flexing situation. (Like at an angle into a driveway.). When our sway bar bracket broke, the arm slipped out, and I call the 'wooden wagon bounce'! (Others call it a 'baby buggy bounce'
!). I was able to get the arm back into the bracket slot, and made another few hundred miles before it came out again.
Colton Truck did a great job of fixing/beefing up both of the sway bar brackets for me. I went ahead and replaced the sway bar bushings at the sometime.
Suspect Kaiser Brake & Alignment would have no problem also fixing/beefing up the sway bar brackets.
This was in our 2004 40' Allure...
Best of luck to you,
