Hi!
I would like to improve the winter traction on my truck with a posi rear end. Is it possible to build from my stock Dana 44? I suppose most people switch to Ford 9" but I would prefer keeping my stock rear end if possible.

Nice looking truck! Is that a lever-action Winchester in the rack?

I don't know if your diff carrier can fit a limited-slip, but these guys could tell you: RANDYS Worldwide Automotive

 

Hey Mats

Long time no see. I see you have gotten some snow up there, what a beautiful picture

I had the very same wishes when I started my build. To get some better traction on both wheels.

I made some reading and found out that something called "true trac" or as we say over here "torsion diff" would be the best for winter usage.

Then you have the old limited slip (spring loaded cluth) but these can make you loose traction when cornering, but then they are a bit cheaper than the true trac

This company has limited slip for the Dana 44, BUT you need to maek something about the axles as this one have 30 splines and yours has a lot less but I cant remember the count"
Machine your own or find replacements...

Dana 44 - HP Series | Auburn Gear Aftermarket

Or you may find a torsion diff somewhere here, but samething goes here need to make something to the axle splines

When I added everything up with new ring gear, pinion, axles, seals bearings etc it was close to the same money as a new/rebuilt 9"

 

That is a beautiful truck!!!!

 

Yes, you can get a limited slip carrier to fit the Dana 44 with the correct spline count for the older axles. Any good gear shop should be able to help get the correct part. I added a limited slip to my Dana 44 about a year ago.

 

Thanks a lot all of you!!!

ALBUQ F-1. Yes, it's a Winchester but I also got some heavier things under my seat just in case Putin and his guys arrives!!

I am going to call a gear shop and see what they come up with. I am also going to mount a weight in the back of the frame. In addition to better traction I think the leaf springs works smoother too.

Thanks a lot guys! I am really appreciate all help i got from you!!!

 

That is one beautiful rig you have there. Love the wheels, tires and hub caps. Excellent combination. Maybe another dana 44 up front would do the trick

 

Thnks a lot, GB SISSON.
Yes, a 4x4 would be great! Maybe a reson for one more truck!!!

 

I have found that after ten or eleven trucks, your wife doesn't notice anything different when another appears. I always make a big deal about the cash when I do happen to sell one, making sure she gets a fistful of Benjamins for a shopping spree. Oh, a Benjamin is a hundred dollar bill here. Go for it!

 

My dad and I learned about this when buying guns. After a while, she wasn't able to tell them apart so as long as we didn't go with something too wild, we could clean it right in front of her and she'd never even know!

 

For good or bad, for whatever warped reason, some of us just collect. We just do. I once had 30 or so antique Briggs and Stratton engines from the '20s and '30s. Many had overhead valves and stuff like bronze rocker arms, some were 'straight fin', some were 'slant' fin. Some were double flywheel some were single. They had names like an A or a B or an H. Then there were the FB and the FH and the elusive FI. I even had a PB for a while. Once I bought 3 of them for 30.00 and sold them to a collector in Indiana for 1200.00 . They were called a 'motor wheel' and were a bicycle attachment. My then wife would come down to the shop and never even ask "hey is that a new one?" How would she know? Sold 'em off over the years, mostly for money for truck parts. Now I have two left.

 

I see Auburn sells a locker for my 56 F250.Not near as cheap a 100 but thanks for the link anyway!!

 

Hi Mats,
You may want to do some reading on differentials. Positraction is first generation limited slip and pretty old technology at this point. It is fine as long as you are going straight ahead, are on level ground and don't make any turns. IMHO there are much better choices particularly for a pickup truck. You might want to start here:
http://en.wikipedia.org/wiki/Limited-slip_differential#Viscous_.28VLSD.29

The later ones are good all-around choices:

• Viscous
• Gerotor pump
• Electronic Diff

But the Electronic brake based system has a tendency to overheat the brakes in tough conditions and usually only works at very low speeds.

Check some of the Jeep or 4x4 sites as the Jeeps use Dana 44s also. Here is a site that sells clutches Detroit Lockers:

Good luck,

 

A "tru-Trac" should slip right in.

 

Thanks a lot petemcl and critterf1. I am very glad I asked before I made a decision what to buy.
