Hello, all. My name is Mark and our family just purchased a 73 Painted Desert. I've been reading this site and others before we purchased our coach, so I am somewhat familiar with the general workings, quirks, etc. of our coaches, but am still mostly new to GMCs and motorhomes in general. Ours is a mostly restored coach, but on the 1200 mile ride home, we did notice some issues. Some are now solved, (had a heck of a time with vapor lock on the Onan in the Texas heat (ended up doing a pusher pump on the fuel feed) and I had to rewire the dash HVAC fan circuit to run it on high) but this last one I am less familiar with and was hoping for some help/advice.
I've noticed the right front side of the coach in particular riding lower since the trip. (Rear appears to be normal) The other day, I jacked up the coach to inspect and maybe adjust the torsion bars, and while the left torsion bar adjuster is kind of in the middle, (where I assume it should be) the right side is completely maxed out. I'm not too familiar with t-bar suspension setups, but it seems to me like my right bar is failing, and I assume the previous owner compensated for this by maxing out the adjuster. There also appears to be a fairly pronounced curve in the right bar, whereas the left bar is mostly straight.
Am I right in thinking I have a failing torsion bar? I read that there is an option out there for an upgraded replacement bar (Huber bar?) but I am not sure they are available now, and with just buying the coach, I don't know that they would be within our budget right now, anyway. Other than used, are there any other replacement t-bar options available? If not going with new bars (which I would assume you would always want to replace in pairs), is replacing just the right side t-bar with a used one an option? Or should used bars be replaced in pairs as well? Also, I don't know that it matters, but our coach is running the Manny 1 ton front end.
Thanks in advance
Mark
