Dana 60 Trac Lok odds.

[Phily]

Sorry in advanced if this is too much of a newb/noob/loser question.

From everything I've read, and I've read alot, searched alot, etc. I have found that the Dana 60 trac lok can be found in the M1028 and M1031. I have also found that nothing guarantees a trac lok to be found however, as there are cases where the front dif was found to be open. Is this rare to find a 1028/1031 w/o a trac lok? or just a common occurrence? or somewhere in between?

everything i've read says that it's not common....pop the cover if you can, if your looking to buy a truck hoping it has a trac loc then you can try locking/unlocking hubs and turning the front shaft while preventing one axle joint from spinning with a bar....a worn out unit might appear to be open but a good unit will prevent you from spinning the shaft, spin fast!

BTW, most of my posi checking has been on rear axles w/gov. lock, in thoery the front should be just as easy to check out.

Your way of figuring out if the front has a LSD is brilliant. I never thought of checking like that.

When you say "not common" is that Not common to find the LSDs or not common that M1028 and M1031 have open front difs.

LSD, what is this, the 70's

uncommon to find them in any vehicle, so i've read

That's what I was afraid of.

its just a posi which is not very good anyways. put a arb in it and you can select when you want the front locked and un locked !

All 1028 & 1031 came with the "Trac-Lok" in the front Dana 60. You may get one with reg open diff. but that's due to someone in maint changed it out for whatever reason. A couple of other points that you can fig it has "trac-lok" is 1) if the 4th digit in vin # is a "H" (with one exception) which is the M1010 Amb. 2) If it has the "overload extra spring on the rear axle . Also if you are able to look at the center housing, If it has two of the small tags held on with the cover bolts, one of them will read "Use limited-slip fluid". Also you can tell w/o taking off cover by removing the filler plug and look in hole and you can see part of the clutck pac. They can with it but like I found out at Warner Robb abt a year ago, I won a M1028 "fire-truck" disination, when son & I look at front end during pick up noticed that the bolts on spring plate were not tight at all (about 1/2" still to go. NO TRAC-LOK.

Right. but I would prefer a OX locker however. Not a fan of Air lockers.

I agree LSD's are nothing compared to lockers, but LSD's are much better than open difs. The thought of a OEM LSD in a Front D-60 sounds kind of like a GEM.

I did the same thing only I just locked in one hub and I couldn't get the driveshaft to spin, I was pretty suprised at how well they grab!!

The air lockers seem to have a lot of failures with air supply
The electric lockers seem to have a lot of failures with wires....
i'll stick to my posi's

I bought a 1028 recently without seeing it first hoping to get the true trac. It does have one

And thus, enter a OX locker. No electric. No air. Strictly mechanical.

another alternative;

The "Trash"-Locker LSD is better then an open front differential and can be made better then OEM (maybe not $$ practical) it is at the botton of the list for OFF-ROAD capabilitys. The ARB (air) compresor can come in handy for other things if properly riged & The OX Locker (mechanical but with cables to adjust and mantain & seems to pop-out at the worse time) but are good choises.
During my M1008 "end to end" Dana60 build, The route I went was with the Richmond Powertrax "NO-SLIP" locker.
Big brother to the practical & highly regarded "LockRight" and 35 spline axles with Warn (rebuildable) hub lockers (clunky during turns, but stout enought for the CUCV power and can handle up to maybe 39"-40" tires) there are several brand choices with +/-

powertrax lockright locker

I recently installed one of there units (p/n 2620) in the front of my M1008...I figured from all I'd read, that I'd have to remove the carrier and ring gear to remove the pinion shaft, and there was even a photo on the web of a guy who had ground part of the ring gear away, so that he could remove the pinion pin...there was enough clearance that the carrier didn't have to be removed to access the pin, so it was a fairly easy instal, and it operates very well....Wilf

Well I'm lost, All I know is when I lock in my front axel on my 1031 it works. lol

Nice. Love hearing those storys.
