Axles

So my build sheet for my 98 4cyl TJ says that I have the following.......

Front axle: Dana 30/186mm axle
Rear axle: 175mm with 4.10 axle ratio

My question is this, what rear axle do I have? and is there anything I should look at as far as upgrading? It is mostly my dd with possible trailing now and then this summer. I bought my jeep that way it is. It does have 35's and I'm pretty sure a 4" suspension lift.

Also what are the possibilities for lockers on these axles?

The rear axle is a Dana 35 and those are the stock junk axles. They are c-clipped and will break with 35's on it if you wheel really hard and have a heavy foot. Putting a locker in the D35 would just make it weaker. It wouldn't be worth it. There is a Super 35 kit that say makes it stronger but still I wouldn't trust it. I would just buy a dana 44 and put in the rear and then you can lock it.
For the Dana 30 they are a good axle as long as you don't go higher than 35's and you can lock them with ARBs, Detriots and any locker out there. They can handle the tire well and won't break as easy a D35 with a locker in it.

OK thanks for the info. Was not sure what that rear axle actually was from the build sheet. I guess I will start pinching pennies and start looking for axle options. LOL

I ran a dana 30 / super 35 with ARB's and 4.10's for quite some time with 35's and wheeled the crap outta it with zero problems.

I've read in several places that the super 35 is actually a bit stronger than a 44. I'm sure there will be doubters, but never had a lick of problems with 'em.

Only moved away from 'em 'cause I didn't think they'd support the current setup and for $250 for my dana 60 and a free 14 bolt, couldn't resist
