Jack,
I had steering box/steering arm issues while at the factory. They weren't much help on my older coach, but I did manage to find the casting number for the box and quite a bit of information.
TAS 855289 this is only a casting number. There should be a 6 digit part number stamped someplace on box itself. I was told near the shaft, but couldn't find it. There could be some interchangeability.
My arm (the one that attached to the box and goes down to the rack was bowed. There was/is no replacement and it appears to be a custom part. Thankfully, I was able to use the Newell maintenance shops' hydraulic press and gently/slowly straighten it out. No creases were evident. And the 24hr trip back showed no anomalies.
My steering box has a small weep, and will likely need rebuild at some point. There are several companies I've located that will do the rebuild. and/or straight exchange at somewhat reasonable prices.

The poppet valves on the steering box are critical to safe operation. See above docs.
Hope this is helpful.
