This is about the most realistic answer I've seen so far.

When measured frame depth on an 08 Chevy HD 2500 vs an 08 Ford F250 the HD had a deeper frame.

The Ford owes it increased capacity to the solid front axle.

Good question - I don't know.

I would think that depth would be the primary characteristic in measuring perpendicular or shear strength though.

Perpendicular strength - cross sectional area is your primary concern.
Shear Strength - width and thickness of the upper and lower cross sections of the C-Channel (And their distance from the center of the channel).

GM HD frames bend like a wet noodle, Im constantly pulling them after they have been in a minor wreck, or because they bottomed out the low front crossmember offroading. The rear section seems to be pretty stiff. They still dont even compare to a superduty frame, I dont care what the frame depth measures or how much boxing or ect. The steel on the GM frames seems to be very soft, and they bend very easily, just like the rest of the truck.

Softer steel? Could be. I am not an alchemist - so I can not say either way. I'm sure your right though.

Couldn't prove it by me. Both Ford and GM use 36,000# HSLA steel in their HD frames. It is true that the front ends of the GM frames will get damaged in front end collisions. The repair procedure is to cut off the ends and weld new ones on. The only full size pickups that I see that seem to need frame work often are 1997-2003 F-150's. And on those it is always a hard 'T-bone' to the front wheels. Control arms are stiffer than the frame.......

I bet that may be a reason why the 04's and up have aluminum A-arms

The weak spot on them is in the firewall area where the frame curves, I dont think theres a procedure for changing this section of the frame, The cut and replace section is only at the very front of the frame, Ive changed plenty of those as well. The control arms often bend the frame in on the GMs as well. Plus the weak ball joints are always ripping out.

I'm guessing they are made of plastic. Probably a weaker plastic then Ford I'm guess'en

Im not just trying to rag on GMs, I used to be a die-hard chevy man and I still am into the old GM trucks and cars, Im just dissapointed in the way they build these new GM trucks, I had a 2004 GMC and was constantly bending or breaking something with the IFS, I use and abuse my trucks so I need something tough, which is why I went with a superduty. I pull frames for a living so I sorta understand which frames are tougher than others, Ive pulled plenty of superduty frames and could show you the exact weak spot on them as well, but from what Ive seen they hold up much better than a GM HD frame, it also takes alot more pressure to pulll a bent superduty frame.

Not to get off topic or anything like that. But in sled pulling. The GM trucks are always having giref with there front ends. Tie rods. Idler arms. If its not one thing its another. A buddy off mine is diehard Gm guy an admits solid front axle is the only way to go on these trucks. Hes a sled puller an is thinking off ditching the IFS to go to a solid front axle. Its still my opinion Ford is tops when it comes to build quality. They just have a more solid built truck period. Nothing against the GM trucks but Fords are built tougher for work an abuse. Like one off my buddies said. I want a truck to go a cross a cornfield at 50 MPH an not have to worry about the truck falling apart. He said only Fords will hold up to that abuse. A friend off mine has a 2005 Superduty. He overloads that thing everyday. One day I was at his place an he had a huge load off round bales on that truck. I said man your overloaded. Nah Im fine he said. I do this all the time. Its a Ford no problem. I said OK looking for one day the truck breaks in half or something goes major wrong with it. He also has a Chevy in the yard a 98 1 ton model. Hes had about everything go wrong with that truck that could go wrong. Tranny,clutch,front end. He said its a nice truck when it runs but it just cant take any kind off hard use. Hes looking for another good Ford to replace that Chevy. Hey now this is just my 2 cents for what its worth. So take it or leave it. Sorry if I riled any off the GM fans up. Its not my intention to cause any controversy just stating opinion.

The problem with GM HD ball joints is not the joint itself. The problem is the upper joint comming loose from the upper control arm. The joint is pressed in, and under certian extream conditions it can come loose, PARTICULARLY IF THE TRUCK HAS A LIFT KIT! Some of the lift kits are poorly designed and put too much stress on the upper joint. The ball joints on the GM HD's can be greased, unlike the plastic-lined joints that Ford uses. Never seen a GM joint wear out yet.

Just GM HD ball joints right? S10's are horrible on ball joints. and I have seen complete failure on a few 1500 series ball joints. Fords ball joints.....they straight up suck. My f250s were junk in 19K miles and I constantly have to replace Explorer and f150 (97-2003) ball joints. Dont know if the 0'4 up are any better, but I havent had to replace one of them yet.
