Default Building a Front Narrowed D60 for a TJ

Alright, there has been so much discussion around here about a D60 instead of putting money in a D30 or building a 44 I'm now looking into this. BUT, only if I get a good enough deal on a perfectly good HP D60 Front that will work for me.

That being said. I never plan on running anything bigger than 35-37" tires (if I can afford some sort of highline to fit the 37's, I'm all about being low with my LJ). So I'm sure a BallJoint/Unit bearing axle will be fine.

I may have the opportunity to get a front axle from a 2002 F350. I would want to narrow it to about 63-64". I just need to know if this is the right axle to be working with or what axle should I be looking for?

I just bought a HP,ford, kingpin 60 for $600. Saw a few less desirable 60's for $400-$500.

I need to know if this 2002 F350 HP D60 is short enough on the drivers side that I just need to shorten the long side to try and get that 63-64".

Also, what bolt pattern is this? I have some new aluminum rims that fit a 2004 E250 (8 lug) but I know where was a difference somewhere along the line with standard and metric bolt patterns.

It is a metric pattern, We can re drill to most other patterns.i would have to measure the width to see were your pig would end up taking all from drivers side.
Stock is around 69.5". We typically take 5" out of long side, so another 1/2" wouldnt hurt.

I'm not having a very good time trying to find axle dimensions online.

And I'm finding that 2002 was an interesting year for axles. That a SRW F350 might of had a D50 in it. What is the difference between a D50 and a D60? I'm going to go check this axle out and need to be sure I'm looking at what I need.

Yeah, you have to be very careful if you get a 50 or a 60. A 50 has a smaller ring gear, I believe 9", and has dana 44 sized innter shafts, that then get larger to the larger u-joints. Kinda like dana 60 on the outside and dana 44 on the inside..

That is a real tough tire size. Big enough to start breaking the 30s and 44s, but you drag a 60 with those size tires.

I dont think any F350 had the dana 50s only the F250.

You are right about the tire size. It's a real SOB to be honest. Everything I talk about building another D44 people tell me i'm wasting my money. I liked my last 44 I built for my CJ, but I did break shafts running 35's.

For the money I would find the right 60 and build it once. I'm switching mine to 1/2 ton brakes and 6 lug. I'm going to take 7" (not in stone yet, haven't measured the old axle yet) off the long side and shorten and respline the shaft. Depending on what parts you replace ect, i guess less than $2k total. Locker has a lot to do with it, Detroit is like $550 or something.

35's and a dana 60?

if you go with a 60 you almost have to go with at least 37's

from center line, *from a post on Pirate*

Dana 30 4 7/16" completely un-modified
Dana 60 6 1/8" completely un-modified
for a net loss of 1 11/16"

37's will gain maybe an inch or so back

i vote for 9in front

Use a lot of skinny pedal and keep momentum on your side!! You'll just slid over everything then.

I second this. I am currently building a TJ that will be running 4D's. I got a shaved C&C 14 bolt in the rear and a Waggy 44 in the front. Not the most desirable axle for the front but I already had it and parts for it. It only has a 2.5l so I am hoping I will be ok.

I vote for a 9" as well.

As far as the bolt patterns are concerned they switch to metric starting with the Superduty from what I understand. So 97 F-350s and 98 F-250s should be metric and anything before that should be 8x6.5 the 97 F-250s are IFS with 7 Lugs.

You could always use a dodge axle if you want the standard 8 lug pattern. Not sure if you have a rear axle already but I think the 2011 Chevys and GMCs now have a larger metric pattern so maybe just keep it in mind for future projects.

Sorta. 97 f350 is a standard pattern. There is not heavy duty f250 in 98 model year. 99 is the first year of the SD and will be metric. 2003 is a 60 front in the SD for what i under stand.

in mid 2002 the super duty pickups quit using the dana 50. too may warranty axles.
ford only used the d50 on the excursion after that(that is what i was told anyway). my 2002 superduty is a dana 60 front. the dana 50 and 60 look the same on the outside. the 50 is 30 spline inners and outers. the 60 is 35 spline inners and 30 spline outers. check the bom number or measure the ring gear to be sure. many people online have tried to sell the d50 as a d60. ill take a few measurements of my super duty 60 as soon as i can. the diff location and size may limit uptravel on the diverside. it always looked like a kinda short left side to me. i have this issue on my buggy. it places the diff right under the left frame rail. i got 80k on the ball joints, and over 100k on the unit bearings. my rig was loaded pretty heavy sometimes. should work real well under an lj other than the size of it. they can be shaved for clearance. all the super dutys had the 8 on 170mm lug pattern unless you got a 450 or bigger.
vans might be a different lug pattern.
ill get ya some measurements asap.

Excursion used Dana 50 throughout its production

F250/F350 SRW used Dana 50 until Jan 2001 then switched to Dana 60.

F350 DRW used Dana 60 throughout its production

FWIW, I'm planinng a Ford 9" center / Super Duty outers this fall in mine, which is 36s now, maybe 38s later, and 350hp V8. I don't really want to go to 40s, its just not what my club does, and the 9" can be better clearance than my existing 44s.

2 easy ways to tell a D50 from a D60

1- d50 is 1 1/8 pinion nut and d60 is 1 5/16 pinion nut

2- measure from the mounting surface of the diff cover (on the housing) back to the very end of the housing where the pinion comes out.
edge of housing to edge of housing = 12.5" = D50
edge of housing to edge of housing = 13.5" = D60

A superduty axle will have unit bearings and ball joints. I don't understand why the Ford D60 unit bearing gets a bad rap. They last 150K miles under a powerstroke. They will be fine on your Jeep. I'm running unit bearings on the new buggy. You can take the stock unit bearing and get them redrilled to 8 on 6.5"
