2nd Gen Non-Engine/Transmission Dana 80 in Second Gen

[JTruelove]

In an 02, auto did the rear end come with a D80 or D70 HD? Also looking at a wreck truck how can I tell which is which?



Thanks

As far as I know, the auto's came with a 70 (except the DRW's). The Dana 80 diff cover is quite different from the 70, taller if I remember correctly. Hopefully someone will chime in who can explain an easy way to differentiate the two.

I believe the truck had to be built with a manual transmission to get the Dana 80.

My '02 3500 DRW Cummins auto has a D80 in the back.

All duallies got the d-80

The manual trans 2500 got a modified 80, autos got the 70.

Fox has it right.

I *think* 80's will have a sway bar and 70's will not.

 

[Bill Lins]

Sway bars only came with the camper package. Sticks got 80's, autos got 70's.

axle tube on 80's is larger in the middle and necks down as it goes into the pumpkin, the 70 is the same size all the way.

70 in the auto, 80 in the stick and all dualies

Thanks to everyone who replied. The 02 auto does have a 70, but it did come with a camper special (overload springs and swaybar). I am picking them up today and soon will have rear discs on my 99

#@$%! U-SUCK :-laf Just kidding.



So jealous. :{ I've been putting up with the drums on my 99 since 01. They've been doing ok though.



I "think" the rear disc set up (rear end from the 02) may have some different fluid system parts that you may need to complete the conversion. Like: proportioning valve, rear anti-lock, bed level/load sensing valve thing that's in the fluid line.



I don't know if you are picking the rear up or if it's being delivered? Get as many little fluid system parts from the donor truck as you can . . .



Let us know how things go for you.

I don't have a load sensing valve and the ABS is on the rear diff like all the others. The parking brake setup might be different but it's still a drum.

 

[JTruelove]

Actually I got the MS, ABS module, prop valve, emergency brake cables, speed sensor on housing, along with camper special springs, all the hardware... I paid $640 for it allOo.



I feel very pleased. I also picking up the the fuel module too for $30

One thing you might notice is the axle will be at least 1" wider than the old one but won't be an issue.
