    I have searched this and didnt find a whole lot. How can you tell a dana 44 and a dana 60 apart. Are there and markings or easily identifiable marks on the housing or maybe casting differances? Also what year trucks are they most likely to come out of? What years will be a direct bolt in for my 87'? I am also curious about a 14 bolt are there any years that wont be a direct bolt in for me? I was also at the bone yard this weekend and seen a couple 14 bolts and a couple that looked similar to a 14 bolt but on the front side by the pinion there were about 5 or 6 bolts that looked like you could pull the pinion out or something?? Any idea what rear end this might have been?? Any info will be a help.... Thanks in advance.

    The best way I know of to distinguish a 44 from a 60 is the Dana 44 will have 3 studs holding the steering arm to the drivers side knuckle, the Dana 60 is a different style and uses 4 to hold the steering arm. The Dana 60 is also a fair bit larger than a Dana 44.
    Sounds like the diff you found was a 14 bolt.
    Check the home page out, there is a visaul guide to axle identification there that should help. I'll look for it and post the link.

    Also on the passenger side the springs are held on by one U-bolt and 2 studs on a d60.

    O.K sounds good I think I should have no problems identifing a dana 60. Now when I was at the bone yard there were some what I thought were 14 bolts which didnt have the 8 bolts holding in the pinion? What were those, looked like the same drums and thing but no bolts? any ideas?

    Dana also marked some of their differentials with a model number. If you are looking at the front of the differential and imagine the cover is a clock face, look at about the 5 o' clock position and there will be a flat machined area on the housing just to the right of the cover which may have a model stamped into it. My 60 has a 60 stamped in it right there. I read that in some chevy truck book.

    If the ones you were looking at were full floating axles, but without the 8 bolts around the pinion, I'd say rear Dana 60 out of a Ford or Dodge. Pretty common rear diff for those trucks.

    14 bolt is suppose to be stronger. What you might have saw in the Burb if it was a 14 bolt (count the bolts on the cover) might be a semi float axle. If you plan to put a 14 full float in your Blazer you might need the backing plates from that rear so you can hook up the e-brake. Look to see if the e-brake cables are differant lengths, then they should be the ones you need. If you don't need them thatK30guy (Wes) is looking for some.
