1995 F150 2wd to 4wd

I'm wanting to know if anyone has tackled a 2wd Twin-I-beam to 4wd straight axle swap on these series of trucks. I have a 1995 F-150 XLT, 5.0L EFI, single cab, SWB, twin fuel tanks, E4OD trans, 3.08 rearend. I have a coil sprung dana 44 with 3.73 gear that I am planning on using, and will swap out the rear gear for 3.73 or may drop both to 4.10, but I am wanting to get some info on transfer cases and if there is a knockout plate on the cab floor for a t-case shifter. I have the capability to build all types of brackets for this type of swap. I am planning on a trans rebuild in the near future and need to know if a case swap might be necessary to mount the t-case.

first off, its easy if its coil sprung and you can use your existing shock towers. Essentially a straight bolt-up with minor fab work.

Second, if your wanting to re-gear, make sure if you do 4:10 in the front and 4:11 in the rear or 3:73 in front and 3:74 in the rear and so on. The front should be one less.

Third, any small block tranny will be fine (e4od, zf-5, mazda 5 speed ect) as long as its has a tranfer case, naturally.

As far as mounting a t-case on your 2wd tranny, im not sure about the e4od trannys nor the mazda or zf.

thanks man, I believe the only fab work i need to do is to cut away the pivots for the I-beams, I think I could hang the axle in a day or so. I read that the E4OD was used in both 2wd and 4wd trucks and vans, but i dont know if there is any variation in the cases. I believe I could even use the stock radius arms.

Just look for a 4wd model of your truck and pull the transfer case off it. The tail end of the transmission will need to be taken from the parts truck too. Did the same to my truck. The E-4OD has the mounts built onto it for the 4wd selector in 2wd models. the there is a little cap that I cut out where on the 4wd models have the stick shifter. You can see where it is under the truck and its not hard to do at all.

hawgstyle is right. The trucks are all built the same way, just compensated for different models, options ect.

not trying to steal your thread, but will a t-case off of a 4wd mazda 5 speed fit on a 2wd mazda 5 speed?

@hawgystyle, when you say the tail end of the trans, do you mean just the housing, or the output shaft as well. If its just the tailhousing, ok, but the output shaft removal woud be a bit more labor intensive

@Duct Tape Racing, Running the same gear in both axles doesn't matter because I will not be driving the truck on the road while it is in 4wd, and I will also have the front hubs unlocked while driving on the road. The Gear ratio difference is so minute it will not matter. The difference between a 4.10:1 and a 4.11:1 gear ratio is only .036 degrees of driveshaft rotation for every 360 degrees of tire rotation. In the mud where the tires will be slipping anyway, it won't matter.
