Not sure if this counts as drivetrain or not but.. in my manual i see that i have a Dana 60f front axle, but it doesnt spesify if i have the 70 or 80 in the rear, I'd assume one is for 3/4 and the other is for 1 ton, but which is which?

 

There is a tag on the diff that will tell you if its a 70 or 80...You could really tell the diffference between the two...The 80 is a huge rear end..

 

you have a dana 80 rear thats the only one that came with a manual


my bad you said in your manual......If you have an auto and the axle has not been swapped then you have a dana 70

 

look at the adhesive tag under the hood, behind the grill; open the hood and look up you'll see it. there is specs bout equipment on your truck.
mine says: Code Nr: DRE - Description: Rear Axle Spicer 70 (99 3/4 Auto)

Yup, Dana 70 Power-Lok (if Limited Slip). The manuals had Dana 80's but were Trac Lok type LSD.
The Pwr-Lok is prefered by most and the Dana 70 is a stout, quality rear axle.
The 70 handles almost anything we can throw at them..... except for serious repetative Sled Pulling.

If interested in an original factory equipt list you can take your Vin # to a Dodge Parts Dept and request a 'Build Sheet'. Should be free.

47RE = Dana 70 in '02

 

Sweet!! Perfect thanks guys good replys. Ill find out for sure tomorrow when its light out again. Thanks

 

As the others have said, if it's an auto you have a Dana 70. 5spds have the Dana 80.

All 1st Gens regardless of tranny had a Dana 70 rear.

 

Dually's also came with the Dana 80 running either Auto and Manual transmissions. I can see that your truck is not a Dually, but just for your information

 

The D80 can be had with a Plok from the factory. I had one. It is a coin toss on which LSD you could of had in an OEM D80, though. Just wanted to point out they could have come with either one.

 

Mines a trac lok. 6-speed H.O.

Thanks, Your 98.5, right? Sounds like a few were still left over. Bet there were no D-80 Pwr-Lok's in 99... or later.
I'm not a purist, and suspect the Trac-Lok is more than fine (if plates are restacked) for our members needs.
But I know of no maintenence problems with the Pwr-Lok.... and it is a beautiful and sophisticated system! Maybe just got priced out of existance?

Blasphemy!!!

Yes, mine was a 98.5.

Seriously, the Tlok does bring the suck. Viva Le Plok!
