which rear end?
i was wondering which rear end i would have. the truck is a 1983 f350 4x4 crew cab single rear wheel. i thought it was a dana 60 but the manual i fould in the truck says dana 61-1 which i have never heard of. thanks, tim

A variation of the Dana 60 known as a Dana 61 was made to accommodate gear ratios that allowed for better fuel mileage. This was done as a direct result of the 1973 oil crisis. A 3.07:1 gear ratio was common for these axles and unachievable in a regular Dana 60. To allow for the different gearing, the Dana 61 had a greater pinion offset. This offset meant that a different carrier and a different ring and pinion had to be used. The Dana 61 was made in semi-float and full-float axles for select 4×2 Ford ¾-ton and 1 Ton Pickups and Vans from 1974 to 1987. A Dana 61 front axle was selectively used in Dodge 4×4 ¾-ton and 1 Ton pickups from 1987 to 1993. Although 3.00:1 and 3.07:1 gear sets are possible from a Dana 61, lower gear sets (4.56:1 on down) are not.
I hope that helps.

thats too bad. i will have to check the gear ratio in mine. those gears are great for the highway but not so good for towing. i did notice it was pretty doggy pulling the camper but thought it needed a tune up. thanks for the info. tim

well it looks like the 78 i bought may end up being a donor since it ended up being a rust bucket. it has a dana 60 rear with 4.10 and a dana 44 front that i might swap in. just not sure how much work that would be.
