What posi in my 12 bolt.
I can use some advice on the 12 bolt 6lug posi 3.73 I have. I opened it up and what I see are like three spider gears in a U shape. I saw in the book some type of posi that had a flat sring like device in the center and a clutch disks. I would like to know how to tell if the positraction is in working order. I did hold both axles and could not turn the pinion. Both axles turn the same direction when I rotate the pinion. How do I know if this is in need of a rebuild?? My boy needs this for his 12 bolt 5 lug that is making some serious noises. Can we put the whole carrier and pinion in his with the posi and put back his 5 lug axels?? Sorry about all the question I am not up on this stuff. We did pull the axles to see how it all worked from what we have read. Thanks Ed ke6bnl
