LXI SUSPENSION ISSUE

I like the plumbing on your schematic much better than what I had on my LXi. With this scheme we have 3 bags per side leveling the coach and we have more roll resistance offered by the tag axle, plus it auto adjusts to increases in tongue weight proportionally distributing tongue weight to both drive and tag axles. Seems superior in all respects. I wonder why BB ditched this approach in favor of the tag axles tied together and supplied by a regulator. Could be they did it to have better control of steer axle weights. As coaches got heavier the tag air regulator made shifting weight on/off the steer axle easier.

I'm convinced more than ever, given this new air schematic, that Al's issues are HCV or Panhard rod related.

I added your diagram to our Document Library:

David,

I am still mystified as to why Al's tag axle pressure is set so high. When he gets each axle weighed, it will shed some light on how the axle weights are affected by that extremely high tag axle pressure. It may be causing some of the problem. BTY, I'm wondering how Al's tag pressure got to 100 psi. Maybe the PO replaced the pre set relief valve (center connector block) with an adjustable regulator valve.
