Seems like it's easy enough to mig weld closed, but what kind of force can shear the front cross member of a 3/4T truck? Perhaps this happened when the cross member was first formed? Anyone else see this on their trucks? this crack isn't wide, but the length is approximately an inch, and starts where the cross member ends, and meets the frame rail..

Re: 3/4T Cross member shear
Hi,
I had an identical crack on my WC 53. Not sure why it cracked as I did NOT have the same crack on my WC 57 which I suspect had a tougher life then My "53.

Re: 3/4T Cross member shear
i have had a few WCs crack there. the frames have no gussets because they are designed to twist a whole bunch offroad to keep all 4 wheels on the ground. something has to give at some point. so many of these crack in that spot and never get any worse i cant see it as an issue to be concerned about.

Re: 3/4T Cross member shear
Kaegi, thanks for the explanation. I didn't even think about the twisting motion . Makes you wonder where these vehicles have been in their lifetime. If only they could talk.

Re: 3/4T Cross member shear
I hope you take it out and do some offroading if you havent already. they really twist alot. it ads to the unstoppable performance.
