I know I replied to this thread. Where did it go?

Ill re-type it.


If youve got a sterling now I wouldnt swap it out for a 70.
Basically the same axle specs

70:
10.5 ring gear
1.5" 35sp shafts

Sterling
10.25 ring gear
1.5" 35sp shafts

Detroits for the 2 are almost the same price ($589 for the 70 and $599 for the sterling). I would swap in some D70 ring gear bolts and a 9" solid pinion shims into the sterling for added strength and security.

I like sterlings because you can remove the brake drums without pulling the shafts.


prices were from www.completeoffroad.com

why would you a sterling 10:25 is a good heavy duty axle..what are you going to be doing with it to make you think you need a dana 70?

If this line of thinking was reasonable nobody would be running rockwells

Then again, reason may have little to do with what we do (!)

I have worked on both axles and I don't see any advantage in swapping. Stick with what you got.

Some of the guys i've worked with swear by the dana axles (personal preference) And another reason to swap it the dana 70 has a bit more ground clearance than the 10.25 which is a plus when im offroading.

i had to get a new(to me) dana 70 for my truck, from the junk yard it was about $800 with 3.73s and no LS or locker. i dont have any knowladge of the 10.25 but i do love my dana. it is nice that i can take the axles out with out taking the wheel off, nice for wheeling if you brake stuff. and it has the inspection plate so you dont have to take the center section out just to "inspect" it. but i do know that lots of people say that gonig from the D60 to the D70 isnt worth it because of the loss of ground clearance isnt worth the extra stringht.

Wait wait wait. I think youve got your axles mixed up. Only the Sterlings have removeable brake drums without pulling the shafts/hubs. If after you take your tires off the brake drum comes off you have a Sterling. D70s are just beefier 60s and are basically the same as far as style and setup go. The only real dead giveaway is the tube size. The covers and in most cases the brake drums are the same. You might see a little more webbing around the center section but not always. If you paid $800 for a sterling or 70 you got ripped off big time. $150-300 is about right from salvage yards and sometimes cheaper for non LS.

IIRC a D70U has about 3/4" less ground clearance than a D60 but about 1 1/2" more than a 14B

still seems a little steep but I guess prices do vary from coast to coast.

I still think you have a sterling though. Is there a drain plug in the diff cover?
