If he sleeves and gussets the housing he has now it will be almost as good as a 60 and he can do it all pretty cheap.
The tubes and C's are the same, the differential is completely different. Cant just gut a d30 and through d44 parts into it.....

If your gonna make the upgrade go rcv's. I blew up the yoke and ujoint in my d30 w/ the stock axles. Replaced them with some pretty expensive chromolly shafts, and twisted the splines on one shaft and blew up my spider gears at the same time. Mind you this is all with open diff's and 33's Long story short said company really dropped the ball on the warranty and I didn't get replacements. So now i'm back to some stock shafts I picked up from another jeeper and an aussie locker, jsut so I can use the jeep as a jeep again, lol.

I am however getting a pro-rock 44 with rcv's in the next few months b/c I'm sick of the weaksauce factory junk that is the d30.

The problem here isn't the u-joint, it's the axle shafts. The axle shaft ears are weak and they are flexing. This flex causes the clip to pop which, in turn, allows the u-joint to move and eventually fail. I'll agree that the clips aren't the best design but they have been around for decades. If you have properly forged axles you'll see very few issues with them.

keep in mind you are comparing an rcv shaft to stock units. there is more difference there then just ujoints. there is nothing wrong with ujoints. many people have no problems with their chromo shafts with 300m ujoints. which is a more fair comparison.
