I would highly recommend a Tru Trac for this application, but unless I missed something when I was looking for mine, they don't make one for the Dana 70. All I could find short of a Detroit, which I also would NOT recommend for towing, is the Power Lock diff from Dana/Spicer. You are not going to be doing anything stupid with this thing so that should suffice for your intended usage. Ideal?? Maybe not, but the road manners are faaaaar superior to the Detroit. If a Tru Trac was made for a 14FF, I would have one in my Sub instead of the Detroit. Unfortunately one is not made for it and I will suffer with the road manners of the Detroit so that I can enjoy the trail manners of the Detroit. The Power Lock can be shimmed tighter if you need more, or just give your parking brake a couple clicks to help it out in real ugly situations.
 
Dave I think you are over-thinking the whole thing. My dmax has an open rear end( some of you may have witnessed it). For towing its great, and since your CC is 2wd you will not be taking it in hairy situation. Hell even with my dmax being 4wd I tend to stay away from getting in trouble. I say leave it as is and see how you like it. I would say tires with a decent tread pattern would be my first investment. Hell I had to pull out my brother last week because he got his 1500 4x4 with a limited slip in the rear out because his tires were regular radials. I didn't even have to use 4wd to get him out.
 
Actually I think the ARB is pretty much the only option here. Being that it is 2 wd, it may get stuck pretty easy, an ARB while it won't be used often will be worth its weight in gold ( or about 30 minutes unloading the maiden and using it to pull out Bart and trailer :D)

Fully locked 100% traction when you need it open when you don't.

If your gonna add a traction diff, thats what I would do

2nd this
 
Always comes down to the most expensive option on this site dosent it:rolleyes:


:haha::haha::haha:

CK5 will make the most frugal of us go broke:D

Man I love this site:thumb: Wallet and GF hate it, but I love it.

Selectable really is the best option,(pretty much always) But for a truck that MIGHT see 2-3000 miles a year:dunno::D
 
Here is the scenarios I envision:

towing my camper (7K lbs?) and getting to a camp site, (Silver Lake) which includes some short sandy hills, which I have used 4wd to get to with my 99, but think I could make it fine w/ a locker back there and 4 tires turning....only 2, I don't think so without some other assistance???
The parking lot at the drags can get muddy if it rains alot (rte 66 in Joliet) we have been parked in muddy areas before and I'd rather not get stuck in it, again the 99 w/ G80 has gotten out good, but I've seen many one leggers get stuck in there. (the racetrack has helped out w/ tractors but I'd rather avoid waiting on them).
so 95% of the driving, right no traction adder needed, but as you all know when you need it they are invaluable.
 
Ummmm........ My MIL's husband got stuck at the Yogi Bear in Silver Lake once. OK it was a 2wd powerstroke, and he was old as dirt, but it could still happen.:dunno:
 
I'd say if you aren't going to wheel it hard then do the TruTrac. You won't be rock crawling it so no need for a full locker. An ARB seems like total overkill for a 2wd tow truck.

the site I stay at is a friends with a couple small, but somewhat sandy hills, easy to dig into pulling a trailer.

Am I reading correctly that a true trac don't work in reverse....that would be an issue for me.

I'm also not seeing one listed for a D70..... so is this a D70HD, D70U, D70B, D702U??? whats the diff?
 
Where did you read that it doesn't work in reverse? I think that's not true. I don't 1 tire fire, ever.

That's not true. Look at the gears, they don't care which way they are turning. If oneside goes faster than the other its gonna bind up, forward or reverse.

good to know then, thanks Luke, but do you know if they make it for a 70?
 
I would imagine they do. I paid about $500 delivered to me in Canada. From Randys ring and pinion.

Yours should be a D70HD.
 
I have never had the same experience Luke has had with high HP rigs and the tru trac but I can tell you off road they sometimes do not work so well. Most of the time they work great but I have witnessed a tru trac equipped rig spinning one tire while the other was not.

Kind of the reason I say ARB the ONLY time you will need it it may save you from a tow bill.

I know more than one person who has put an ARB in the back of their 2wd tow rig and they work out very very well.

It is of course the most expensive option but since I have seen a tru trac slip, that is what steers me towards the ARB.
 
Eric, in your experiences have the truetracs slipped in a towing type environment, or strictly off road type stuff?
I've seen some at the drags (knowingly that they were a TT) and watched launches, and straight and true everytime from what I've seen. No slip, or the car would have launched to the side.
 
Reading those sentiments, I have never "hard-core" wheels my diesels. Been in the mountains lots but not hardcore by anymeans. Eric.I'm curious if those were actual Detroit trutrac? Or something else? Or maybe.they were broken already? I dunno.

So I figured I try my own little experiment on my drive home from the mine. Nothing scientific, but very convincing. Conclusion for me was I am not able to spin 1 tire. I just can't.

Left tire dry pavement flat, right tire 4" wet snow on top of frozen grass on a sideslope. No sign of 1 tire fire. The truck just drives, forward and reverse. And really rooting on it spins the tire on the pavement. No video being alone on a desolate highway.

I think my biggest challenge will be with it in a muddy field, with little load on it, or trying to climb a small sandy hill to park my camper in my space @ Silver Lake....It takes 4wd in my 99 to get it done, but I could always back it in, and that might be better for traction too. Right now its just easy to pull through in 4wd.
