Crazy steering wobble/shake
Hello all, I have a 2002 Itasca Horizonn 39qd with a Freightliner XC chassis -- 3126e CAT. It's got 65K miles on it and has been recently serviced and well maintained... so just the other day...

Well Gang,
In the OPs answer to me on the history of his ownership of the coach, he stated he's had it for quite a while, many, many miles and it: HAS NEVER DONE THIS BEFORE! So, I suspect that, he's driven with just about every combination of loaded tanks, unloaded tanks, loaded coach, unloaded coach, acceleration, deceleration, cornering, bumps, dips, hard stops, soft stops, towing, not towing, and much, much more and any combination thereof.
And, It's never done it before. So, is it possible that, for the very first time, after years of ownership, that, he's encountered a driving/coach condition that he's NEVER encountered before? I kind-a doubt it. I am not a front end expert, nor a physics professor so, trying to figure out what kind of weight transfer/shift that could cause his situation FOR THE VERY FIRST TIME, after owning the rig for that long, would be very tough.
Our rig, the sister ship to his, an 04 Itasca Horizon 36GD with the 330 CAT, (only ours is 3' shorter) is an incredibly heavy rig. I could load those black, gray, fuel, and, 31 gallon propane tanks in any combination of full/empty and (and have had it at multiple levels of each) and never tell the difference in handling or, performance.
This is why I asked him how long he's owned it, and, has it EVER DONE THIS BEFORE. His answer was, a long time and, it's never done it before. So, what's changed in the last couple of weeks that might be the issue here? He's had supposed reputable companies analyze the front end, alignment and more. An unbalanced tire, enough to cause shaking, is going to manifest itself each and every time one reaches the speed at which it starts to cause issues. But, this problem is not consecutive. It happens, then, it doesn't happen with driving conditions duplicated. I hate when some things "malfunctioning" only part of the time.
