dana axle question

Hi guys,

need to pick your brains, got my self some axles, i think they may be Dana 44, they came off a 1979 Chevy Blazer K5, on the logbook for the vehical, it states that it had a 2.8 litre engine in, although it came with a 5.7 v8!, anyway it has 10 bolts holding the diffpan on.

I tried to take pictures with my phone but it kept saying it was busy, how the hell can my camera be busy.....

In '79 the front axle should be a GM Corporate 10 bolt, your rear axle could be another 10 bolt or a 12 bolt.

Never seen a 2.8 in a full size, its a dog of a motor in a mini truck so I don't think that GM would waste the effort putting it in a k5.

Was this a Blazer built for the UK or one that made its way over there some other way? If its right hand drive you should post some pictures, that would be kinda interesting I think.

if the tie rod is on top of the stearing arms that are cast into the nuckle than its a dana 44, if its on the bottom its a corprate 10 bolt.

All dana axles have the model cast into the center section. Iicr its on the lower right or left of the center section. This should help you determine what axles you have. Notice the little "ears" on the bottom of the 10bolt. Those usually give it away.

Thanks for the help guys,, my front is a GM Corporate 10 bolt and the rear is a 12 bolt. as for the 2.8, thats what it says on the paperwork and it is left hand drive...

next question...how strong are they, will they cope with 37 inch creepy crawlers driven enthusiastically! mostly in mud.
