Frame Sag?

Another question to post today after pulling more of the floor out.

Right behind the axles, both of the C channel part of the frame are buckling inwards. I have a welder coming this week who does a fair amount of work on airstreams, but I want to know how serious of an issue this is before they get here.

The plates that were welded onto the frame have both buckled outwards as well.

I have the frame level on jack stands right now. Should I raise them more to compensate for the possible frame sag?

Thanks in advance

The axle mounting plates were not welded to the frame as they should have been, which in part has caused the issue.

The next item that causes that problem, is excessive tow vehicle in terms of rigidity, excessive rated hitch bars and finally, lack of proper running gear balance.

Lift the frame so that it bends about 1 inch or so upward, then do the welding as necessary.

I am surprised that the trailer does not also have a case of rear end separation.

If it does, hold off on the welding until the separation is fixed, which when done properly, requires the removal of the rear quarter panels and removing most of the lower rivets that hold the panel below the rear window in place.

We have a drawing that we can e-mail to you, that shows you how to correct the rear end separation, that many others have used, if you need help with that problem.

Looks to me like you have some significant rust areas that will need to be replaced

Any updates on your repairs? I'm a stage past the buckling and have cracked rails. PO "repaired" the street side frame rail crack by welding in a piece of plate on the inside of the channel. Didnt fix the sag before though. The axle plates are wavy from bends and the curbside frame rail is cracked 2/3 through from the top. Still trying to think through how to repair/replace both sides and axle plates while also trying to level out the rear.
