Most 250s had D44s. The easiest way to tell the difference between the two is the 60 will have significantly larger hub bodies on them, 4.5" to the D44s 3" or so. The 60 will also have kingpins, the 44 balljoints.

 

Thats what I kinda figured (most had D44's) but thanks for clarifying the differences, those are 2 real easy tells, Thanks

 

The HD44 and 60 have the same size hubs though

 

That's incorrect the 60's hub circumfrance is bigger than the hd 44

 

I don't have a HD44 so I am just going by what I have read on here. So how big is the HD44? Bigger then the regular 44 but smaller then the 60??

 

A D60 in a f250 is hit and miss. The F250 "Snowfighter" had a 60 up front. But the rest had 44's. You can look at the VIN tag on the door to see if it's a 60. Under "axle code" the last letter/number will be "R" if it's a 60. Of course the Holy Grail of Ford trucks is the 79 F350 4x4.

 

So R is for the D60, what are the codes for the 44 and HD44?

 

Ford put the 44's and 60's frt axle under the f250.There where 250's that did't have the Sno-fighter package (4500 lb gvw) yet they had a frt d60.I don't mean to be rude,but I have no idea what you mean by a R on the dr's axle code designation tells a reader whether or not the frt axles a 60 or not.Where did you get that from?

Those codes are for rear axles?

 

Your correct,but that's pretty much all ya need,By going by the rear you know what ratio you have and then.People can either tell by looking at the frt hubs or reading the numbers/letters stamped on the frt pumpkin or the pumpkin metal tab.Thers nothing else to be had code wise about the axles.If ur thinking about the last letter by the axle code part on the dr tag I believe that denotes pwr steering and or something else.I'm sure someone else will clarify that.

 

Whats the big difference between the 44 and HD44, was the HD under the 3/4 ton and the reg. 44 under the 1/2 ton?

 

Ok I am still trying to get this straight. Someone please correct me if I am wrong.

The low pinion heavy duty 44 was used until 75? and had the same size hub as the low pinion 60.

So the low pinion 60 and high pinion 60 have different size hubs?

Was there a heavy duty 44 with open knuckles and disc brakes after 75?
If there was what year and trucks?

 

Let's say you had a F250 with a D60 rear axle with 3.54 gears and a L/S. The axle code on the VIN tag would read "C7". If your front axle was D60 then there would be an "R" after the 7. The letter "J" denotes power steering.

 

Just the knuckles out. 8lug vs 5lug.
