identifying front axle with little input

what did a 1980 half ton pickup use for a front axle? and how did they get 2.76 ratio out of it (to match the 2.76 out of the 12 bolt in the back)? i've never heard of a ten bolt with a 2.76 ratio (only 2.73).

OK, how about does anyone know if they made a 2.76 ratio set of gears for a 10 bolt? or did they just run 2.73 and say "fsck it"?

Could be a Dana 44, GM took forever to completely change over to the 10 bolts. I've seen a 83 K5 Jimmy with a D44 front from the factory.[img]images/icons/tongue.gif[/img]

Re: identifying front axle with little input

As for the ratio, running something like a 2:73 in front and 2:76 in the rear (or vise versu) is fine. It was more common than most people know. A lot of older Chevys had say 4:10's rear, with 4:11's up front. The difference is so small it does not become a factor. A difference of 3:90's vrs 4:10's would cause problems of course.

As for the front axle, it's likely a corp 10 bolt. But, it may also be a left over D44.

Re: identifying front axle with little input

So you really think they did something like that? Seems kind of weird to me. I know as long as you have less than 1% of difference between front and rear it is alright but it's over 1%. I often wonder if FoMoCo ever had matching ratios front and rear since every one I've ever seen doesn't match.

Thanks, both of you, for the information.
