dana has a web site that has manuals/exploded views ect. available for download. i got mine (no charge) for dana 70 drw and it answered a lot of questions for me.

 

I didn't read every response to this thread, so forgive me if I answer something over again. My truck is an 83 F-250, built at the San Jose plant, and it came with an 8 lug 8.8 rear end. I found this out when I tried to replace an axle, and it was impossible. I replaced it with a Sterling 10.25, and no trouble since.

 

If you are going to use the truck as it was designed, then the twin i beam is fine. If you are going racing or mudding, then the dana 60 would be better.

The transfer case they usually used was either the new process 208, or a borg warner 1345.

 

ok, i just got an 86 f250 4x4 diesel. it has a full floating rear axel, and one side just came out while i was driving, axel breakdrum hub and all. i dont know what size the rear end is, the gears, what i need to do to fix it or anything. i cant afford a new rear end, esp. when i only paid $650 for the truck itself. I hope to turn it into a crawler or mudder in time, but for now i just need it to run for basic ranchwork.

 

A picture is worth a thousand words, cowboy. I have no idea what you mean thre....explain, did the wheel fall off?

 

Please excuse the crudeness here as I do not have a camara handy.



the break drum, attached to the wheel, tire, hub, etc. slid away fom its usual position. the drum is about a foot away from the shoes, and slides in and out with ease. there is a small piece that doesnt move but has theads on it that i forgot to draw. it is what the axel shaft actually slides into (maybe the spindle?) that is still in place.but i was driving down the road in second gear w/ my friend in the bed when the rpms shot through the roof and i stopped moving. he yelled for me to stop, as i had already done, and when i got out to look, the wheel was in the position shown above. when i get access to a camara i will attept to get a better pictre. any suggestions? thanks.

 

Looks like the lock nut came loose from the spindle. You'll have to disassemble it and see what got messed up... How long did it take you to draw that up? In the time it would've taken me I coulda got a job, wait for the first check and bought a camera!Q It works though.Unbolt the axle from the hub, slide it out, and look for carnage. Could get ugly

 

Wheel Bearing most likely failed.

 

The spindle could have broken completely off. I have heard of it happening before. You should see the part in the above picture that says "threads". If you don't then I bet it is broken off.

 

I have had several trucks with Dana axles and the tag was missing. If you think it is a Dana then the ID numbers your looking for are on the axle tube itself. Dana/Spicer calls this the BOM, Bill of Material number. If you have it, you can go straight to Dana/Spicers website and find all sorts of information...

Bill of Material / Where Used~

 

the tags were gone and the dif cover repainted. also i looked all over the housing and didnt find any identifying marks. there is a chance of the remains of a number under the grease on the front of the dif, but only 2 digits. and as for the drawing instead of picture, i go online at college or have dialup at home so i wont be able to put a decient picture. i pulled the hub and everything apart, and found what looks like the inner race of a berring. also, the lock nut will screw onto the threads but wont tighten and has (i think) way too much play onced threaded on. sorry for makin this difficult. also, i tried giving the VIN to the ford dealership to see what all is in it, but they said it was too old. if anyone can inturprate it for me please, or tell me how to.

 

You can identify the rearend the hard way. First the easy part. If you have a oil fill plug in the rear cover of the rearend, you have a Dana. If it's smooth, and the fill plug is on the driver's side front casting, then you have a Ford/Sterling rearend.

That was easy, but now the harder part(not that hard really). Take the rear cover loose and let the oil drain, and then take it completely off. Count the number of teeth on the large gear, and the number of teeth on the smaller gear up inside the front. Take the big gear number and divide it by the little gear number, and that's your ratio.

Since you have a f250, if you have a Dana, you more than likely have a Dana 60. Dana 70's were under f350's and dually's.

 

one more Limey's query '


I have a 1986 F250 6.9 diesel SRW Supercab 8800 lbs VIN : 1FTHX2516GKA66532 and really need to know whether I have a full or semi floating rear axle..... Am sure it's a 10.25" Sterling, but is it a full or semi floater ? Need to order parts, and being asked the question by the part suppliers here in the UK

 

Full floater will have a cylindrical protrusion from the center of the rear axle that goes through the center of the wheel for about 4 or 5 inches with bolts on the end.

Semi Floater will not have this protrusion and the center of the axle will be almost flush with the brake drums.
