Vertical slits after jacking for new wheels

[flamingo-kid1]

We had new wheels and tires installed today, and the technician at the tire store was very careful in jacking up the trailer, First he jacked up the right side and installed rims and wheels,and then jacked up the left side and did the same. When he lowered her, I noticed two vertical slits in the aluminum on the right side, one to the left and one to the right of the wheel well. Upon close inspection, there is one small slit on the left side of the trailer, (in the wheelwell) also. Can anybody shed any light on this odd problem? I had my camera with me, and took "before" and "after" pics, although I won't know if I actually captured the wheel well "before," since that wasn't what my lens was after. I have to get the film developed to see. The trailer WAS jacked up very carefully by the area on the axle beam, he put a jack on each wheel axle on each side (two jacks) so how did this happen???? Anybody heard of it before???

Sounds like your stringers popped through, if they're on your belly pan.

Usually happens when your body mounts are worn out and bouncing occurs.

Good luck with the repair. Cliff.
