will it fit?

[yenkojoe]

Can i put the rear end from an e250 onto my f150? the van is a 92 i believe and the truck is an 86

Thanks Joe

i believe you can. the good thing about ford is the interchangeability of these vehicles is awesome. the only thing i think you might have to change is the drive shaft flange. on the older vehicles (early 90's and down) have the u-joint directly bolt to the flange on the axle from the drive shaft. on early 90's and on the used a flat flange on both the drive shaft and axle. its the same thing i ran into on my posi(Trac-Loc) axle i built up. the axle came out of a 94 and my trucks an 89. different flange. all i have to do is change the flange on the drive shaft to the correct one off of a 94 and the ale will bolt right up

Thanks that sounds sweet, ive been eyeballin it since we dont use the van anymore, it is a good axle i dont know what it is but its a trooper in general.

oh the other thing is...is the truck 4wd?? because if it is you have to make sure the front axle and the rear axle have the same gear ratio

 

[yenkojoe]

no, th ef150 is only 2wd like the van. How can i tell what axle it is and the gears?

Not if it's a mall crawler, and you don't use 4x4 like some members on here (not naming names )

I'v heard (and don't hold me to this, cause I haven't tried it and can't confirm it) that you can spin the a wheel exactly 2 turns for open diff/ 1 turn for posi diff. and count the turns of the output shaft, however many that turns is the axle ratio.

Example = you turned the wheel 2 turns (open diff) and the output shaft turned 2 3/4 turns the ratio is 2.75.


EDIT: I searched around to make sure I was right, and here's a link to a better explanation..

or the easier way would be (assuming the axle has never been changed out) check your V.I.N. tag on the door jam of the cab on the drivers side. there should be an axle code...something like "34" or you can check the axle tag on that should be attached to the rear diff cover on one of the bolts. it will say something like 3.55 or 3.08 something to that effect

 

[yenkojoe]

thanks. i will have to check out the axle code. And country ive heard that too, i just remembered now.

 

[yenkojoe]

the van rearend i have says it is a 24. that makes it a 3.73 but not a limited slip like i thought, but im pretty sure that it has limited slip... now im not sure anymore

What about 9" rear diffs?Mine has no such tag.I decoded mine by the Door sticker.


Tyler,thanks for reminding me about my crappy 2.75 gears.

Worst gears to have in a truck.I can't wait til I get some lower gears for it.

Thats what she said...

 

[yenkojoe]

lol thats why im a dickwell. it fitswell

 

[89frankenford]

pretty much the only way to check for an LS axle is take the diff cover off and look for the clutch packs.

hahaha, sorry!

And yeah, you need some 3.73's atleast..

pretty much the only way to check for an LS axle is take the diff cover off and look for the clutch packs.

Or, if it's installed, just powerbrake it (in the grass would be easier on parts) and see if both wheels spin...

I strongly suggest not gearing any lower than 3.73.

3.55 would probably be perfect for you.

 

[yenkojoe]

its weird... im ny truck it says i have open 3.55s but i just did a sick nasty burnout and i lit up both tiers...

Maybe the PO installed posi?

I've seen it said if you use a thicker weight oil it helps turn both tires. Several people have said this so I don't know if it's true or no.

If you were to jack up the rear end, start the truck and give it fuel would both tires turn if you have posi? I know this works with a locker but I don't know how limited slip works 100%.

Edit: I see you have an '80 Camaro. Any pictures???????

the van rearend i have says it is a 24. that makes it a 3.73 but not a limited slip like i thought, but im pretty sure that it has limited slip... now im not sure anymore

1959 thru today cars/trucks:

If the AXLE code on the Warranty Plate (thru 1980), or on the Certification Label (1981 thru today) begins with a letter = Limited Slip, if with a number, no Limited Slip.

24 = Dana 60 (or Dana 61) / 3.73-1 / no Limited Slip / 5300 lb. (5400 lb.) Rear Axle Capacity / After 1986, Econoline's only used these two rear axles.

You do realize that by installing an 8 lug Dana rear end into an F150 will require carrying two different sized spare tires.

You will also have to change the companion flange, maybe the driveshaft itself....as the rear U-Joint of the Dana will not be the same as the 8.8" or 9" your truck has now.
