I own a 2005 FoRi High Wall Popup - HW256. We bought it barely used in '08 and have used it 12-15 times since - not a lot of wear and tear. Last Fall when we went to cover up the camper, I noticed as I slid my hand under to put the tire cover on that there was very little clearance between the tire and the camper on the right side.
Being cold and windy, we covered it up and let it set until last weekend. When we uncovered it, I checked again, and of course the clearance was the same. To check it out, my husband hooked up the camper and rolled it around the parking lot at the storage yard. We took it to another spot to make sure it was on the level and to see if there was any change, and it was the same. There is enough clearance that the tire doesn't rub, but again, it is close (maybe an inch). The camper is not loaded (just has a few sheets, pots and pans and the like in it).
We crawled under looked to look at the axles, and on the side with the low clearance, the torsion bar/arm seems to be pointed more downward (and from the pics I have seen, that should be better, I think). On the side with the normal clearance, the bar is about level. When you look at the camper sitting, it does not appear to be off-kilter.
We are thinking we may need a new axle, but not sure where to start to confirm, or what size (I tried to look it up somewhere - you would think this is on a parts manual somewhere...but I got frustrated).
My husband is a tractor trailer driver and has done all our repairs. He doesn't think this would be much to change if we had to, but wanted to get more info before we embark on this project. He was baffled by a torsion axle, said he had never seen anything like it.
Does our issue sounds like its the axle? Does anyone have a schematic? Does anyone have the part number (I think they are made by Al-Ko) without me having to drive back to storage so I can research parts and prices? Everything I have read says we should upgrade anyway if we were to replace it.
