What transfer cases and front axles were available in 73-75 F250/F350 4wd pickups?
Thanks

Weeeeeeel, what is actully in each truck can depend on a LOT of different things but what there was available is pretty straight forward. Dana 44 of course, these had bigger hubs,knuckles, spindles, and i belive the axlehouseings were larger/thicker than those available on F150 and F-100. but the axle shafts themselves were the same. the Dana 60. Quite the piece of iron they are. there were both high adn low pinion applications, with the high pinion in 77-79 trucks with the snowplow package, they also were beefed around the centersection. For t-cases, NP205, 203, (full time) i think, Borg Warner 1350 (or a similar number! i forget) i think thats it.dont hold me too it though.

 

Actually it was the Dana 21, NP 203, NP205. The 21 & 203 being the most common.

 

Just for sake of discussion - its my understanding that between '73 and '75 that the F350 was not normally available (i.e. not special order) in 4wd form. Someone please correct me if I'm wrong.

The '73-'75 F250 (commonly referred to as the "highboy") used the Dana 44-6CF and 44-6CF-HD front axles, which were low-pinion closed-knuckle drum-brake axles built around the D44 center section that came in 3325 lb or 3550 lb GAWR's, with the primary difference being in the brakes/hubs.

The Dana 21 was a 1/2 ton case. Transfer cases for the F250 during those years were the NP 203 (maybe) and the gear driven NP 205. The NP 203 is a full-time case and relatively rare, it's not even listed in my '74 shop manual and I'm not sure it was installed between '73 and '75, I think that a majority of the trucks had the NP 205 in a divorce-mounted configuration.

Hope this helps!

 

Thats correct, the F350 4x4 wasn't even available until 1979.

I've seen all three t cases in 67-77 F250 4x4s.

 

Do any of ya'll know how to tell the difference between a D44 and D60 by looking at the outside? I know about the diff. in size of the ring gear....Thanks for the help!

Look for a metal tag that may or may not still be affixed to the diff cover. There should also be a number stamped in the webbing of the pumpkin indicating which model axle you're looking at. As a last resort you can always "eyeball" it - compare the pumpkins on the front and rear axles - if they look alike you're probably looking at two D60's - if the front is noticeably smaller then you've probably got a D44 front/D60 rear.

 

My old 75 F250 had the dana 60 in front. You can ID it buy the huge hubs, look like a coffe can(almost) it was a 4500 lb rating as opposed to the 3800lb

 

rakent, where at in the webbing is this number exactly- I've looked before and came up empty handed.....
Thanks

PS- I know the D60 has a '60' but does the D44 have a '44'?

 

Would Ford have put a D70 rear in a 75 F250 4x4 Crew Cab? A friend of mine is restoring a 77 CC using a 75 4x4 frame, axles, ect. He claims it was a F350. I haven't seen the 75 (rolling frame only) for a couple yrs, but I'm almost sure it had a D70. It has the ball-type knuckles on front so it's before 76, right?

 

Well, the series number (30, 44, 60 etc.) is usually on the right-hand, bottom pumpkin webbing facing the rear, together with an id number stamped on the axle tube (right hand side, I think.) I've been able to find it on some newer axles. However, if the axles are like mine and have seen 30 years of dirt roads and more than a few winters it is quite likely that these have been destroyed by surface rust or hidden by solidified axle grease, dirt, etc. - I've looked for the numbers on my '74 and they simply aren't there anymore.

Sorry I can't be more help. If it would help, I'll try to measure the pumpkins on my truck when I can get a chance to get underneath.

awesome- thanks a lot...
I really appreciate your help

Greg, it is possible that you have a D70 rear. I've only seen these on F350s, we have a 74 F350, that is a super camper special, they only came with D70s. A lot of F250s came with Dana 61s, this was fords "Mile Maker" axle, and was offered in 3.07, 3.3, & 3.73 ratios... Its usually seen on camper special trucks.
