Terrible Cab Flex Issues.Minor Damage.

Today I went ever so slightly off road with my f-350.I was pulling a trailer with two four wheelers down a rocky,rutted road with dips and holes.Nothing major, and I took it easy.When we arrived, and I got out of the truck,I noticed the passenger side bumper/fender gap had increased.The driver side bumper/fender gap had decreased to the point that the bumper was into the fender.It also appears that the driver side negative battery post got into the fender edge under the hood.The intercooler boot clamp stud has been rubbing the air intake snout.The passenger side cab mount nearest the coil spring tower looked normal.The driver side cab mount was squashed and split in several locations.Moving the truck to a different location resulted in the gap returning to normal.Either the cab or the frame is flexing very badly.I can't believe this .It literally blows my mind.Built Ford tough?I hate to think what would have happened had I "really" gone off road.I was so embarrassed.Nobody in my group had ever seen anything like it.Now they think my truck has a weak frame.Maybe it does.Any suggestions?Thanks everyone.

Sounds like you need new body mounts.

The truck isn't weak, it's worn out, like Zaair said.

I am hoping that replacing the cab mounts will cure it.But,with that,several questions arise.
1)12 years of age and 128,000 highway miles.The stock ones sure don't last long do they?
2)Only the very front ones look worn.Should I replace every one,including all of the bed mounts?
3)Stock replacements or urethane?
4)I am in no position to tackle this myself.The dealer would be premium price service.Perhaps a 4wd shop,who performs body lifts,could do it?

Thanks for your input guys.When this is over I will post part numbers and prices for those interested.

The factory mounts are rubber. The bed is mounted using steel. I'd upgrade to urethane bushings if you can find them. Any shop is going to charge at least a few hundred bucks for the job. I'd find some friends, bbq, and beer and do it that way.
