What are there for specs on rebuilding my 3.07 open Dana 35? I need to put in new diff bearings because the PO put in a new pinion seal and never tightened the nut to spec now I have noise when I'm on the throttle. My unit is a 1991 with the AX15 and 4.0, and it also happens to be my daily driver. At the moment I can't afford to look for a Chry 8.25, and i want to keep the same ratio of which I don't see a 3.07 ring and pinion for the 8.25. So that is why I need to know what the setup specs are on the D35. Anyone have that information?

sure its not your u-joints?

I did a search and found this. >http://www.sija.org/bounty/Misc/D35PinionSeal.pdf
Go to the part for pinion shaft seal replacement.

AX15 with 3.07? What kind of mileage to you get? Just curious...

It's not that I'm just gonna have to replace the pinion seal again, just have to setup the ring and pinion to get some more life out of them till I can afford to replace both front and rear ring and pinions with something more appropraite, like 3.73's. I know the rear u-joint needs to be replaced, but I always thought that they needed to be replaced when they vibrated or sqeaked, not make a whining noise. I'm only running 235/75r15's and I don't plan on going any larger on those anytime soon, but I have read from the other posts on here about MPG going up by getting away from the 3.07's. Yes, my MPG is not as good as I want and i drive about 50 miles a day, and with gas prices the way they are, i need to find loopholes. Can't afford another small car at this time.

Anyone have any idea where to look up the setup specs on a D35? Is there a place I can get a service manual online?
