Glad you enjoyed it and found it useful!
Great information. Well done
Thanks!
Very good video
Awesome video my 1999 cummins auto rear differential is staying lock in all the time drained and add limited slip additive and fluid still staying lock in this video is awesome this will help me pull it apart and repair it thanks also any avice on why it's still staying locked in all the time Makes noise when turning Slow speed
Clutches could have been overheated and warped so they are putting pressure on each other all the time. Thanks for the comment and good luck!
@@screamindieselltd Excellent vidéo! I rebuild mine yesterday, it s not a big big job, the most important thing is when you tight the 8 bolts from the case, we need to tight slowly , en at the end you can ear a sound like click, I think it s the convex plate and clutches take place . So thank you for this great vidéo !
Thanks!
Anytime
Super,,, but what's the torque for the 8 bolts or nuts that hold the rear shaft to the spindle.??🤔🤔
95 ftlbs.
@@screamindieselltd ok 95 then... Thank you very much sir.!!
Hey any idea if I have to swap bearings will I have to re shim it ?
It’s always got to check it.
Hola, disculpa el kit que mensionas le servira para un diferencial Dana con el numero 21494x, es de un pick up Ford F250 año 1970, me comentan que es un diferencial dana 60, gracias.
O que kit le servira a un diferencial Dana 60
So i’m looking to rebuild my differential and swap the gears from a 4.88 posi to a 3.55 lsd is there anything i’ll have to change and will i have to set back lash?
The carriers might not work as the break is usually 4.10. You should set everything up again. Like pinion depth, and backlash. But if your swapping everything over from another diff you might be able to get away with swapping shims and everything. Although it is best just to set it all up again.
Muy buen video felicidades me puedes mandar direccion o telefono donde pedir ese kit y numero de parte gracias ace 11 meses q tengo mi troka RAM01 4X4 CUMMINS PARADA POR ESO AYUDA Y GRACIAS
Why didn't you replace the pinion bearings?
Didn’t need too. The clutches were the problem.
@@screamindieselltdhmm..
Might as well put new bearings and seals if you went that far
How much difference is there between a Dana 70 and a Dana 60
I haven’t been into a Dana 60 as far as this 70. But from what I’ve seen of them they look the same just smaller.
@@screamindieselltd could you make a vidéo about all bearings shims, to calculate preload ... about the dana 70.
Would you know the part number for the clutches and steels
I have a open dif in my Dana 70 and it sucks the front .I bailed on the vacuum system and put the cable posi Lok on it .been looking around for a locker to rebuild myself
What year dodge?
This was a 2000. Should be the same for any second gen (94-02) Cummins with a Dana 70 with posi in the rear. 2003 and up are an AAM axle so they might be different. I haven’t got into one.

Thanks this was very helpful.
@@doncunningham2332 your welcome glad you enjoyed it and found it helpful.
@@gnzabuso1347 Technically, "Powr-Lok". But right, not a "posi" or "Positraction", which is a GM trade name.
that style is not referred as a pumpkin rear end that's a axle housing a pumpkin comes out the other direction and it all comes out ring and pinion no set up . like the rear loading rear NOT A PUNPKIN A CARRER UNIT
Somewhere I read that parts were no longer available for the PowrLok. That basically, if it needed to be rebuilt, you needed to go to a traklok. does that make any sense what I’m trying to say? Maybe it’s the carrier case that is no longer available?
I couldn’t tell you. I gave the dealer the numbers off the vin and the diff/ring gear and they got the parts for me.
@@screamindieselltd it’s actually the Powrlok in the Dana 80 that rebuild kit is hard to come by. I have the exact same unit that you were working on in the video and I probably need to have mine checked out. It seems to chatter when I go around a corner. I’m not sure if that chatter was there before, but I replaced the diff fluid and added two bottles of friction modifier and that chatter is still there.
