I was wondering if anyone could help me here and tell me what I have in my 77 F150 4X4.
The numbers on the frt axle are: ED D7TA-ANA 603808-9-3-50 also if you know the part# for the wheel bearing socket I would love you forever
The rear axle number is; WDM-AE2 7AD 3 50 9 379A.
The only numbers I see on the trans are C-96391 with AH below that and F01 elsewhere with 10-76 below it.
I can't find any numbers on the cast iron T-case??
This is the best I can read all the numbers so I hope they are all correct.
Thanks guys.

 

well i'm pretty sure the front axle is going to be a dana 44 no matter what. is the rear axle semi-float or full float? If it's semi it'd be a 9", if it's full floating (big hubs going through the rear tires, 8 lug) then it's a dana 60. Is the trans auto or manual? If it's manual, if it has an aluminum shift cover it's an np435, if it's an iron shift cover it's a t-18. The transfer case is probably a np205, if you have lockout hubs on the front then thats what it is.

 

An F150 will have a Dana 44 in the front. Uses a OTC #7157 socket.

No LS? Makes it a 2wd is slippery stuff EH???

 

In my Time behind the wheel , after So many miles most clutch plate limmited slip become UNlimmited slip diffs. (Unlimmited = same as a Open)

 

Thanks guys, what can you tell me about the cast iron T-case? All I know is that it looks smaller than a aluminum case and uses 90w oil. Is it chain or gear driven ect...?

 

On the back of a 205, there is a round 3 bolt cover, approx 2 1/2" diameter. This is the part time gear driven transfer case

A 203 has an aluminum rear output housing. Originally they came as full time version, but many have been converted with available kits. They are chain driven.
