The Dana 34 Project: The Ultimate turd polish!

[Ironmanandy]

O yeah, we are aiming for about 300 Horsepower.....

 

[Ironmanandy]

I'm not worried about the unit bearings or the ball joints they are all rated higher than anything I will need.

I got the heavy monster out of the back of the truck this morning by myself.... I'm a little sore.
I only had my cell phone for pics. Here it lays where I plopped it.... This beast is heavy.

I took everything off of it except the ring and pinion.

Here she is bare and ready for chopping. I am going to cut 10" off the width. I want to be about 1/2" wider than the rear. I may go a little more. Ill Decide the final length after I clean the perches off etc.

I will have the long side shaft re-splined by Dutchman. I am debating brakes etc. I may end up running 20" wheels to keep the monster brakes for the monster locking power.
This will mean much bigger booster and master. Glen?

Looks good, is that thing a 60?

How heavy is this rig going to be?

 

[Ironmanandy]

Its a dana 60 from a 2004 F550
35 spline etc. 4.88 gears.
I am going to narrow it this week hopefully

I'm assuming the stock width on one of those axles is around 71" WMS-WMS?

Interested to see how you deal with the constraints of the drivers side when trying to setup a coil bucket/link (assuming you're running coils). Planning on a truss at all? Curious because I have an '88 HP60 (little more room to work with, but not much).

What's your planned tire size? Also, how do you plan on getting the rear to match the metric pattern of the front? Not sure if they make adapters for that, can't remember.

I'd redrill... looks like plenty of space for that and IIRC he's got a full machine shop with a nice lathe to get the new holes done perfectly! (at least if it's a multi axis CNC lathe)

We were just discussing it on the phone a min ago. "Hey go look this up for me!" I'm guessing but Andy helped with my 60 and we trimmed the DS spring pad back some then welded the tubes in place. I'm guessing he might do the same.

Redrill the rear is exactly what he said he thought he would do. I believe the patern on it is 8 x 220mm. I don't know what kinda lathe it is. LOL!

 

[cracker]

should be 8 x 170mm.

 

[RCman]

Cutting 10" out seems like a LOT! You'll probably end up with some major clearance issues running that narrow.
Also, have you priced a 37" tire for a 20" rim lately?

should be 8 x 170mm.

Not the F450/F550.

:doh:

 

[vetteboy]

If you have the single-diaphragm booster, a late 80's Ford E350 master cylinder bolts up.

If you have a double-diaphragm booster, a late 90's Dodge Ram 2500 master cylinder bolts up.

I'm running the Dodge one and it pushes plenty of fluid to fill the 1-ton brakes. Here's a good resource with a lot of (proven) configurations and feedback:

x2


if its an 04 F550 front end, itll be a super 60 with the bigger R&P, 10 lug with bigger brakes and a WMS somewhere in the mid 70's.


it looks like you got jsut a regular mid 00's D60 outta a f350, 8 lug with 1 ton brakes and the WMS should be regular full width at around 69". hell, theres even a chance thats outta f250 and maybe even a D50, the inner shafts are 35 spline, right?

Yea I sugested 17" rims.

This is what I run Andy. I need a 96 booster though. The 97 one does not like my 94 body.

It's the 248 D60. BOM # 2001275-2 I have been searching most of the morning to see if there are any hubs or rotors avaliable to convert his rear 60 to the 8-220 pattern. So far no luck. Anyone else know if there is a hub and rotor that bolts on? Looks like you need some more hubs and rotors to redrill if I cannot find some already to bolt on. :confused1

F-250s used Dana 60 front ends starting in (I think)

(my '03 250 has a front 60).

 

[Ironmanandy]

We ran the serial number and the BOM its definitly from an f550 and they didnt start making the super 60 until 06.

They call it the 248. Its bigger than a regular 60 but not quite a Super 60. It has the 3.5"x1/2 wall tubes and 248 mm ring gear. 35 spline inner and outer shafts. It has 4.88 Gears and the hubs act like a unit bearing but have lockouts..... I did some searching on some super duty sites and the Lockout axles are really rare. I am going to try and find a smaller brake setup if I can.

The width to the WMS is 70.5"

we took off the ten lug adapters before I brought it home. I think that is mentioned on a previous page. It has an 8x170mm lug pattern. I can get an adapter for the rear and make the rear match.
I want the over all WMS width to be around 61.5"

Chevy 1/2 tons in front work really well for me on 35s weighing in about 3800# I don't see needing much more for 37s especially if you put decent brakes in the back.

I thought it was 8x170mm.....

I hope you are going to run coil overs/air shocks on there at 61.5". Also the 37" tires will be in scraping in the wheel well pretty bad (as well as on most LCAs) if the back spacing is not right.

You can't really run a D60 under 64" if you want the coil buckets to match the coil guides on the unibody of the XJ.

 

[RCman]

Its from a 2003 F550.

Its a dana 60 from a 2004 F550

we removed the 10 bolt adapters

... It has an 8x170mm lug pattern...

BOM # 2001275-2 I have been searching most of the morning to see if there are any hubs or rotors avaliable to convert his rear 60 to the 8-220 pattern.

Some numbers are getting crossed somewhere...
I think the confusion is coming from the fact that '99-'04 F450 and F550 DRWs, the axle is a 8x170mm bolt pattern, with the DRW adapter/spacer being 8x225mm. Only the '05+ are 10x225mm.
I'm betting that the 10 lug adapters you thought you removed were really the DRW 8 lug ones.
Ford has been known to do some funky things with bolt patterns, so I'd run a tape across the lugs before I went and did anything. Edit: Post up the results, I am almost positive I am correct but now I'm curious.
