Last trip I took last year I was parked in a weird spot, and the right tag axle tire must have been on a hump, as the coach settled down, the tire pushed up the bedroom floor directly above it. I think I remember reading about that on here before, but I can't find it with the search function. Before I tear into that, what's all between the tire and the interior? Just a plywood subfloor with some insulation and a thin metal plate under? Wondering how big of a surprise that is going to be.
Fill in your signature so everyone knows the year and make. After the repair add a plate to the underside so the tire will span it and not the wood.
Did I read right in that the tire actually broke the bedroom floor loose?
Yes. I walked back there and noticed it was pushed up, went outside and looked, the tire was jammed up against the coach. Aired it up and the floor went back flat.
I thought I filled that out already, I'll go add it. But it's a 99 U320, 4200
I know
nothing about tag axles coaches, BUT, that don't seem right. I would expect a mechanical stop of some kind in the suspension linkage to prevent this from ever happening.
MIght be worthwhile to have the tag axle undercarriage inspected for damage or a broken component?
I agree that there must be a suspension failure. I've driven that same model coach for 165,000 miles without seeing anything like this.
I have owned a bunch of coaches with tags and this is a first. Please take some photos. I would be very concerned if when you aired the coach back up you could actually push the floor back down. There seems to be a large compromise in structural integrity.
IIRC the stop is in the airbags themselves. I wonder if there was some kind of internal failure. My tag axle bag actually separated on the bead plate which started my airbag project many years ago.
