buy a used dana 30 from a junk yard , they are cheeep as dirt .

did you also remove the driveshaft ?

do you keep going through the wheel bearings ? if i remember they are worth 378 $ i threw out my old dana 30 after i pulled the hubs off it . you can get one from some one who did a swap for less then a bearing .

you won't be able to keep running it unless you pull more than the shafts. if you pull the driveshaft, it doesn't prevent the ring/pinion from spinning as the axleshafts will still be turning them. if you pull the axleshafts, then you run the risk of the hubs separating (which it sounds like is happening) on the road at highway speeds...and anyone could tell you that isn't pretty. if you want to keep running it without fixing the differential problem, a good "fix" to alleviate your issues would be to pull the axleshafts, remove the ujoints that connect the inners to the outers, then reinstall the outer shafts - ensure that you still have working hubs before you reinstall/torque the hub nut. keep your front driveshaft removed from this point and then you should be fine. the transfer case can't spin your ring/pinion nor can your wheels - and the hubs shouldn't keep failing either.
at least, that makes sense in my head. anyone else???

I have a question ... What bearings are going out??

Pinion?? differential ?? Hub?? (UNit bearing)

EDIT:
Wait a minute.... I just reread your post .. And now I am even more confused.. What bearing is the same on 2WD and 4WD?? certainly not pinion , nor diff... And the unit bearing is certainly different in 2 and 4WD..

Sooooooooo .. My question stands .. What bearing?





If it where me I would hit a bone yard and find an XJ with a good diff and the same gear ratio.. Then you not only get rid of the old axle you get a stronger one in the trade and I have heard of XJ axles being had for as low as $100 depending on the bone yard..
