    wondering if anybody knows anything about dana60/70? i'm working on a 91 dodge 3/4 ton. i've got a pinion seal pissin all over the place on the rear (dana70) and when i take it apart and replace all the bearings i want to get rid of the "one wheel peel" option it's got and install a aftermarket,or factory style locker, or posi...... or whatever ya wanna call it. i noticed alot of dana 60/70 stuff is sold together/ it seems quite a bit is interchangable.? is it possible to put a dana 60 center section in a 70? any info would help, thanks, pete

    I agree- I don;t think there is any interchagability between a 60 and a 70- there is a major weight capacity difference and the axle diameter is different AFAIK, but the later Ram 2500's all use 70's and the "positrak" (ltd slip) is a common option so check bone yards- may be cheaper than an aftermarket.

    BTW there is a difference between a positraction unit and a limited slip unit- decide which one you want providing you can find both units for the 70. the factory Dodge unit is a limited slip.

    For those not in the know- Positraction means one wheel slips a little then clutches/springs give power to the other wheel in higher proportion than the slipping wheel whereas a Limited slip allows one wheel to slip a little which winds up springs to engage a clutch which effectivly turns the diff into a locked rear end so both wheels get the same power reguardless of slipping. They have different handling characteristics in slippery stuff.
