where can I find/or is the code stamped on the dana front, Vehicle is the 90 bII, which I believe came with the 28 and the 35. Thanks in advance

 

There should be a tag on one of the bolts on the front of the radius arm (cover) for the differential side and hopefully a sticker on one of the beams on the backside. That tag and sticker will give you the axle code and the gear ratio and type of differential. Click Here for rear axle info and click Here for front axle info.

 

I had posted a reply, but when I submitted it, it said something about requiring moderator approval (maybe because of external links?). Anyhow, go over to TRS and look in their tech library, plenty of info over there.

 

Thanks for the quick info. Still cant locate any tags or numbers, but your link was very helpful in helping me id it from the bolt pattern. Thanks again.

 

No problem!

 

You have to look inside the fill plug to determine if it has Dana 28 or Dana 35 guts. I have a 1990 that has the Dana 35 guts.

 

Yea, I read in another post somewhere how to id the dana guts by looking into the hole. Unfortunately, not neccessary for me. After a quick visual inspection of the bolt pattern and small size, my '90 has the dana 28. Inside AND out. Sucks.

 

If you are looking for drivetrain upgrade and are not concerned about having a TTB front axle, you can always look for an Explorer / Mountaineer / Navajo (or even Ranger) with the Dana 35 TTB / 8.8 axles in your local salvage yard(s). Many people feel that the 7.5 axle is junk, but they can be built up and strengthened, unless you are looking to do more extreme things with your BII or don't have the equipment or friend(s) to help with that.

 

Hey, thanks again for the good info Kernel. Am still debating how much work I want to do on the front end. Have already spent two years wrenching on it before getting it back on the road about 6 months ago,so is now my daily driver. I do a good bit of off-roading and camping with it, so my next upgrades when it warms a little is a rear drive shaft uprade and getting the back end back up on some decent springs. My to-do list is still larger than my bank account, so have prioritize abit.
