busted transfer cases!!!!
well one of our local company's is using the ford f-250 2011 4wds for field trucks in a light duty situation. Been getting snow mud and typical winter stuff. Been having a problem with transfer cases busting. If I remember they are at 7 transfer cases so far. If it was just one idiot driver this would be simple. but its different drivers in a oil field situation. just curious if anyone has come across this??? engine 6.2 gasser f-250 4wd.

busted cases!
meaning split cases. used to run dodge 4wd 2500's not a problem but many cummins problems. basically going from one problem to another but a little cheaper than diesel emmission problems. snow mud hills is our situation. trucks are NOT loaded down heavy just getting used with all terrain tires not mudders.

split case!
One driver said he was pulling a hill in slippery muddy snowy situation in the road and truck started to shake and before he could let off, busted case. similar story with several of the drivers. Sounds like a case shock load situation. they really only need half tons but went with the 3/4 tons for a little heavier truck for drivetrain upgrades. but doesn't really seem to matter with the newer trucks these days. good ole np205 is still about the best bang for the buck in oil field situation.

im not one hundred percent sure if the use the same t-case as the 99-04 or 05-10 trucks but im preety sure they are the same. never heard of this problem before, i dont abuse my truck but i do use 4x4 and never had a problem, i've seen guys in my local 4x4 club mud these trucks with 38 and larger tires and i have never seen a ford t-case go before. Are you sure the guys arent turning the 4x4 switch on while the rear tires spinning up the hills and that would cause the t-case to break?

The NV 271-272 cases are super strong, the dodge you talk about have NV 261-262 cases. Which is a smaller case, D maxs have the smaller ones also. your case splitting has got to be user error. the 271-272 are in all SDs up to the 550

I think it was in '99 that New Venture Gear introduced the 271 and 273 transfer cases. The 271 is the manual shift, and the 273 is the electronic shift. As far as I know, these are the transfer cases still used in the new 2011's.
As best as I can remember, I've read of one or two incidents of the aluminum housing cracking on NV273's in the 5 years I've been reading here. I never like blaming something on the user, but when you have several incidents of failures in one situation, and very very few failures reported in almost every other situation, you have to look at what's different in that situation.

Are these manual, or ESOF transfer cases? I can see more opportunity for abuse with the manual, than the ESOF which for the most part prevents user error. Like jamming it into 4L for example while moving.
Could be these employees are not happy giving up their diesels.
Also, I take it the OP is getting this info 2nd, or 3rd, or 4th hand.

The chain driven NVG 271/273 transfer case used in modern Ford trucks is a stronger unit than the old gear driven NP 205. Do these newer Super Duty pickups have a rubbery vibration damper between the transfer case and skid plate like the Excursions? Perhaps adding one would help. The breakages on your one truck are more than all I've ever heard of in the decade I've been familiar with these transfer cases. All I've managed to break is the electronic shifter and I drive this truck way harder than most Ford truck owners can imagine having wheeled in Wyoming, Colorado, Montana, Alaska.

We just had a thread about this in the 6.7L forum a few months ago. Cummins cowboy had his t-case grenade when driving through rural Nevada.
Thread can be found HERE.
The T-case isn't made by NV anymore, and it's a bit different from the previous trucks:

New Process was bought out/merged with new venture gear, NVG fell on hard times when the market was crashing and was bought/merged with magna styer (magna powertrain)! Magna is a Huge company that actually builds alot of BMW's, land rovers, porsches....... in there house, they than put appropriate badges on them! Magna is Pretty much the only game in town for light duty applications (although I believe Borg Warner is still out there). Magna provides all the transfer cases for Ford Gm and dodges 3/4 and 1 tons. I believe they all use the same transfer cases now (except for numbers, and input and output shaft configurations). Please Do Not quote me on this as a 100% fact though! I do know that the GM Hd's WERE running the same for sure though in the earlier days!
New Process Gear was bought out by Chrysler corp, in the late 90's early 2000's, Gm jointly bought into the company and the name was changed to New Venture Gear. GM bailed in like 2002-03,and it was than that magna bought GM's stake. When Chrysler started failing AGAIN Magna bouhgt the majority of the stake (and somewhere in there all of it). GM is runnin a Magna Tcase (may be the same as the superduty with different numbers) but without looking I cannot confirm they are the same as the Superduty.
The T Case in the SuperDuty's is still the NVG 271. On the 11my they narrowed the cases to make up for the new 6spd torqeshift. (? I dont understand why they wouldnt have shortened the rear driveshaft?)
Most of the New Venture plants are now closed (in the States) and what is left is slowly being phased out!

This sounds like low-traction situations, too much wheel slip, and possibly the front or rear driveshafts are too short or too long. That's happened before, I think my own year SD had a certain run of trucks that the front driveshaft was too long.
Is the REAR extension on the transfer case breaking, or the front?
