need to figure this out.

[Speed]

Issue 1)
I need to know how to ID a D60HP front axle.

Issue 2)
I need some sort of diagram that shows measurements of said axle (78-79 preferably).

Its either a 78-79 or an 86-02 or whatever that other run was that had kingpins. i just need to figure out which one it is. Mine is narrowed tho, but i dont know how much and if its even or only on one side. so I need to figure that out too.

Any help would be great.

hmmm. i probably should have put this in tech.

sorry mods... i forgot where i was

Check the BOM number on the front of the long tube.

[Wide-J]

If it has the factory gears, read the numbers on the side also. It will have a date on that...Not that likely that someone swapped old stock gears.

[Wide-J]

Damn it, I can't even send this to Tech. wtf.

aftermarket gears, but cool, ill check that BOM number.
and thanks for the links Rico, I'll check them out.

Soooo, im looking into this whole thing... and im thinking i may have to buy a new front locker too. I have 4:10s and I need to go to 5:xx. the ARBs for a D60 come in two sizes for certain years. 4:10 and down, 4:56 and up. but then there are certain models where it says one size fits all. (this is on polyperformance's site) I pulled up the specs for the lockers on (4:10&down and 4:56&up) and all the specs are the same. ring gear inner and outter diameters are the same for both models. obviously im missing something. anyone got any input on this?

and the 10.25 says its a one size fits all gears. is this truth?

god this is getting to be a pain in the ass.

looks like there are different dimensions


** Note: The carrier is the same for all Ford RC 60's UP TO 98, and is the same as the GM/Dodge 4.10 carrier - namely part # 706040X.
BUT - the Ford RC60 was never offered stock with a ratio lower than 4.10 in those years. When aftermarket vendors started making gears lower than 4.10 for RC 60s - they made the ring gear thick, so it could just go on the stock carrier. So if you bought aftermarket 5.38 gears for RC60 - they would likely be thick. Now - if you buy an aftermarket carrier (i.e. locker, spool, limited slip) for your RC60 - I imagine, depending on where you buy it from, they ask "year/make/model" and based on that would likely sell you the 4.10 down Detroit - that way - if you already had aftermarket lower gears, they would just go on the locker. The problem you might run into, is this:. You buy aftermarket gears first - lower than 4.10 and they're thick. Then you buy a locker by ratio, not make and model, and naturally you'd think "I have 5.13 gears - I must need the 4.56 and up locker" but you get hooped because the gears are thick, and won't go on that carrier. Also note, The 2000+ RC60 Fords are offered with stock gears as low as 5.38 - but these are not thick to go on the same old 4.10 down carrier - they are thin and go on the same GM/Dodge 4.56 up carrier. The carrier break is 4.30 and down go on the 4.10 and down carrier. I don't know if Spicer is the only manufacturer offering thin RC60 gears - but the bottom line is - when dealing with an RC60, you do have to match your carrier and gear set.

To distinguish a 4.10 and down carrier (called a 3-series carrier) from a 4.56 and up carrier (called a 4-series carrier) you need to measure the distance from the face where the ring gear sits, to the end of the carrier, as shown in the following pic - labelled dimension "A".


www.pirate4x4.com/tech/billavista/60_front/images/carrier%20spec.jpg
For a 3 series carrier (4.10 and down, Spicer part number 706040X) Dimension A is 2.225"

For a 4 series carrier (4.56 and up Spicer part number 706041X) Dimension A is 2.360"

fuck cant link the pic... anyway it is all about 1/2 way down on the pirate4x4 link I posted

[Speed]

Yeah, i was reading parts to that link, but then got distracted, ill check it out now.

why do you need to know if your buying new gears and lockers just call Randy's Ring and Pinion and order a matching set either 4.56 and up with thin gears or 4.10 and down with thick. All you should need to know is spine count other than that all Dana 60 parts should be interchangeable the kits come with both style pinion seals. Well HP and LP use different Gears

If you have a gear set or locker that you are reusing and you don't know which break it is I'm sure they will be able to tell you what to measure on you carrier to tell.

If you need to know the inner axle length they will just tell you to use a tap measure.

Just looked up carrier breaks.
Ford/Sterling 10.25" (no carrier break)
I have two 10.25 if your interested in a spare.

thats the thing, i need to make the gearing jump from 4:10 to 5:38. My ARB locker is already installed with the 4:10s, which I assume are thick gears. if I can find thick 5:38s, then Im money. if I cant, im assuming I need to buy a new ARB.

And thanks for the info on the 10.25. its good to know i wont have this issue in both axles.

and i'll keep you in mind if i decide i need spares of anything.

[customcreationsllc]

the break is at 4.10/4.56 so if you had 4.10 then you would need 5.38 thick no question. Never heard of 4.10 extra thin.
Just call Randy's Ring and Pinion they're good help I always use them and on their web site they have a ring an pinion set reverse cut and thick $185
www.ringpinion.com/ProductDetails.aspx?ProdID=3752

If you tell them your from a jeep club they usually take %10 off.

What are you running for tires? I got 5.38 with 35" and it is way too low but I don't drive on the highway.

10.25
The last time i looked into a 10.25 they they had 2 different pinion lengths or something like that and the 5.38 only came with the later style i forgot if it is longer or shorter but I think all you need to do is buy a different yoke.

Good luck
