How does that tag steering work? Does it use an axle with kingpins for instance? With a steering tie rod and possibly a squarish looking block attached towards one end?

It has king pins axle with a tie rod between the wheels with a cylinder lock off center to the drivers side that has cover over it maybe that is what you are looking at,most DL3's will have the steer tag not all do but the majority will it's made by Meritior,you see the same setup on concrete and dump trucks mounted in the reverse position.They lock going forward at 14 to 20 mph but never lock in reverse

Just wanted to follow-up and close this thread out. It took me 5 hours under the bus today to swap out both rear leveling valves. The driver's side valve is particularly tricky. I hugged differential and ate air brake for most of the procedure in order to reach the mounting bolts. There was evidence of previous work on the driver's side valve so I suspect this had become an issue close to the end of the buses service life. I was also surprised to find the manual calling for rebuild or replacement of leveling valves every 50K miles. I had no idea they required that kind of maintenance.

Today wasn't exactly pit crew speed, but it's my first time working underneath the bus and I felt the need to check cribbing multiple times. It's extremely nerve racking to be under the bus and messing with the air suspension at the same time. I learned a bunch today like where the bump stops are, the value of run-up ramps, and how low the bus can go. I appreciate all the cautionary tales on here about properly blocking and chocking.

Final outcome, the bus is on the level now.   

Thanks!

Sounds great! Preventive maintenance at home is always easier than having to fix something on the side of the road at 0 dark thirty on a rainy Sat night...
