how do I know a dana when I see one?
Search this forum.
If it isn't a 10 or 14 bolt, its probally a dana!
60? 44? front or rear?
I have a 90 burb with stock 1\2 ton and I am looking toward the future, wondering what to do as upgrade as far as axels
Its a topic argued about in the garage all of the time. Much of what people will tell you depends on your build plans and how you are going to use the truck.
dailydriver with very min offroad time, just dont want to tear up every time I go in the mud...
Whats the biggest tire you plan on running?
wanted 38 but I dont want to get into gearing and such so maybe 36 or37
For a DD, a 3/4 ton swap would be fine.. 38's will start to get questionable on a balljoint axle imo.. a 3/4 swap is a 14ff and 10bolt, in the 8 lug variety... Tho you could go 14sf to keep it all 6 lug, but that brings up gearing....
And I'll assume you have an auto in there... 700r4... So, if thats the case, your gonna strongly need to consider a gear change when upping your tire size to a 36, 37... you'll burn that tranny up..
Most 3/4 axles you'll find will be 4:10's, which will be ok... 4:56 would be better... here's a gear calc to help you figure out your rpm's...
To answer your original question, here is a link to Dana Axle identifying with pics; http://www.onandoffroad4wheeldrive.com/dana_axle_ident.htm and http://www.onandoffroad4wheeldrive.com/axle_pics.htm It should help you.
yea i am not going to run in overdrive with 36s, so I am just figureing out what way I want to go... Thanks for all your help guys
They also have a tire, gear ratio, rpm at 65 mph chart there too.
Thanks bandit, I am new to this stuff so any info helps
Just a note on 3/4 ton stuff it doesn't really matter whether you have a 10 bolt front or a Dana 44 front. They are very close in strength
