any way of checking the ratio without pulling the cover off, IF there is not tag

Yes, by counting drive shaft revolutions. But:

 

and what year,make and model did the dana 44 come in? cause i converted my truck to 4wd, from a 86 pioneer IIRC

Start at the beginning. Your truck was originally a 2WD. What year, what engine, what transmission?

 

Then you converted it to 4WD. Did you swap both the front and rear axles, or only the front? Are we to understand that you swapped in one or both axles without even knowing what ratio the gears are? What year truck did the "new" axle or axles come out of, what engine did it have, and what transmission?

 

And then we need to know where you want to go with it. If you have to weld new spring perches for the rear axle, the new perches have to be positioned correctly to establish the pinion angle. A few posts above, you asked that that should be. The answer is "It depends." It depends on how much lift you will have, because the amount of lift affects the angle of the drive shaft in the chassis. The spring perch location and pinion angle would be different if you're going to stay at stock height than if you're going to go a SOA conversion.

 

my truck is an 87, 4.0 inl 6 2wd.

 

the donor truck was a pioneer. don't recall what year it was. it had same engine 4.0

 

i swapped both axles and transmission, yea w/out knowing ratio's. at the time i wasnt concerned on what ratio's i got as long as they matched. seeing i were using the original axles from the same truck. I'm not sure what trans i got from the donor, but i think its a 231 cause i have the 2hi, 4hi and 4 low. are  there marks on the tranny that i could check. also my t-case is from an xj so don't know if the tag on that will match the trans

 

no luck on the tags, they were gone. so will pull the cover and check.

 

and how do go about making sure the pinion angles is correct,

auto or manual transmission?

About the spring perches: Rusty's and many others sell a longer spring perch to help stop spring wrap. It should be fine just make sure you get the proper axle tube diameter for whatever axle you use.

As a SOA requires welding it would be easier to get shock mounts and just weld them on then modify the old spring plates to make them work. New mounts are $14.

The auto used in the MJ/XJ was the AW4. The transfer case in the MJ was the 231 while the XJ could have a 231 or 242. You know you have a 231 already. If the donor was a 4.0/AW4 (auto) then yes the ratios should be 3.55 unless they have been changed.

"The auto used in the MJ/XJ was the AW4" huh? i didnt think mine was this seeing it had the 2hi

 

ok first which is which: Part Time has 2hi or Full Time.

 

which one is considered the AW4

 

HOW CAN YOU BE EVEN THINKING ABOUT WORKING ON A JEEP WHEN YOU DON'T EVEN KNOW THE DIFFERENCE BETWEEN A TRANSMISSION AND A TRANSFER CASE? GO TO BARNES & NOBLE, BUY A BOOK, AND READ IT.
