Default Another Dana 30 ??

I don't know if it has been asked or not, couldn't find it in the search.

Exactly what is the difference in D30's I know XJ, YJ, TJ are the same. But what is the difference between these and the older CJ style other then lock outs and they swapped sides? Aren't they basically the same axle? Why does everyone seem to hate the newer ones in relation to the older? Are the axle shafts and joints stronger in the older ones? How bout the ring and pinion, are they stronger? Just something I was curious on, seems everyone wants to get rid of them on the newer rigs but they still run them in the older ones. Thanks for helping me clear up my head!

yj, tj and xj are not the same.

some have the smaller ujoints, some have the bigger ujoints. Some have 2 peice shafts on the long side, some have one peice shafts on the long side.

some are high pinion, some are low pinion.

In my opinion I think a lot of people are quick to rid themselves of the dana 30 when it really is not "THAT" bad of an axle as long as you understand what you are working with.

It has the same size ujoints as a dana 44. (if you have the big ujoints)

In my experiences with a dana 30 on a tj and a yj both on 33-35" tires the weak links on the newer axles seem to be the u joints, shafts, and ball joints/knuckles. I have never broken the pinion or ring gear, nor spiders. I am sure it could happen, but I have been lucky enough to not have it happen yet.

Currently I have 3 complete dana 30's as spares for my jeep. I carry the axle shafts with the unit bearings already on them for a quick swap. I also carry an extra knuckle with the ball joints in it in case of a balljoint/knuckle problem.

I dont know much about the older dana 30's

I knew that they had different joints and high and low pinion but they are still essentially the same, I just wasn't sure what makes the older ones "better". My XJ has the older joints right now, I'm sure when I break them I will put the larger ones in. Maybe it's just a case of someone who only used the skinny pedal and not his head in conjunction with it? I'm sure mine will hold up for a while, it has to my wife still uses it as a DD, but I was just thinking for future plans

I will be running 36's. I like the skinny pedal. I will report back to you on how often I brake, what brakes, why it broke and what I was doing to cause it for you.

New= uni bearings and weaker ball joints

Old= serviceable bearings, dana 44 ball joints and able to use lockouts. All LP.

I took the best of both new and old and built the ultimate 30.



And pulling it for a ultimate hp 44 :miff:

I saw your write up on that, that would be sweet but definitely not necessary for a DD and ocasional wheeling trip. I have a feeling my smaller u-joint's are gonna fail pretty quick though, the terrain out here is a lot different then MI.

Exactly how much better are the serviceable bearings, and why are they better? When they go bad they need replaced just like the unit bearings right?

Lockouts are nice on a DD though

like $30 dollars a side compared to ?? (never bought a uni bearing )

Plus if you keep them greased they will last a long time.

yeah the lockouts would definitely be nice! I'm not sure how much a unibearing is, but they come out easy and no where's near all the grease! lol
