The 10 bolt front could be a dana44, dana60 or 10 bolt. This would depend on the year and model of vehicle, if it's an 84, then they are probably 10 and 12 bolts(1/2 ton). The rear is a 12 bolt. The 10 bolt and 12 bolt are chevy axles.

My 84 had a 10 bolt front and a 10 bolt rear. If it is a 1/2 ton truck with stock axles they are not Dana units.

They are still good axles for the proper application. Keep the tires under 33" and keep it out of a bind and you will be fine. If you plan on abusing it ( or is that called using it to its full potential

) stronger units are in order.

10 bolts and dana44s (fronts) are for all practicale purposes equal. The 10 bolt rear has a slightly smaller ring gear than the 12 bolt it replaced. not any 4wds w/ a dana 44 rear(well my 76 scout had one) a rear dana60 in a 4wd would be 8 lug full float type. a dana60 front would be 8 lug also. both the dana44 abd 10 bolt came as 8 lug versions under 3/4 ton trucks.

If you are wanting a locker I think you are serious enough that you are going to need something a little stronger. Unless you think you can be content with a tire that is 33" or smaller. I have seen people run very large tires with 1/2 ton running gear and never have a problem. On the flip side of that coin....

yea well i want some better axles so......wanting a locker will help me deal with spending that much money.lol
