    I need to get a 10 bolt front axle for my blazer because my new rearend has 3.73 and my front is still 3.08, so I was wondering, how rare is a 3.73 front end with 6 lugs? I was thinking an older Dana 44 with the flat-top knockles already on them, but from what ive heard the 10 bolts are better. I would like D60 but I want to keep both my kidneys, so I will try and find one later.

    Back to the subject. Most blazers and 1/2 ton 4x4's ive seen from our era are 3.08, so any ideas????

    10 Bolts and D44's are about the same in strength. It shouldnt be too hard to find either in that ratio. Its a pretty common ratio. I wouldnt pay more than about $150 for one in good working order though.

    Just look at the axle to make sure it appears to be in good working order. Then pull the cover to check the gears. Thats all.

    3.73s are fairly common...moreso in the older models I think...so look for 73-80-ish trucks. As already stated, the D44 and 10b at about the same as far as strength so you should probably just go with whichever one you find in good condition first. Flat-top knuckles (older D44s) are always a plus if you plan to do x-over steering eventually.

    Ive got a 10 bolt with 3.73's sitting in my garage right now. I got it for free and stole the shafts and hubs off it too bad you aren't closer if CK5 express comes through here and are heading your way you can have it!

    If you keep your carrier and replace the ring and pinion with 373's reuse your pinion bearing (if good) and pinion shim and crush collar as the shim is usually based on how the housing was machined and usually shouldn't change. don't mix up the shims on either side of the carrier and you shouldn't have any problems. checking the backlash and tooth contact pattern is fairly simple and has a lot of documentation out there, if you need installation instructions i can get you some.
