Most will tell you not to lock a 30, or a 35 really. Just do some lurking around the the forums and google. That's what I've done, haven't bothered to lock either of my axels because I don't wheel it enough to deal with the cost. Just got a winch instead... Lol

a lot of people do lock the dana 30 actually. It is a very common upgrade. Dana 35 is not usually upgraded. top selectables are ARB, and Eaton that i know of. I just installed my Dana 30 aussie locker. I am going to test it out today !!

The front Dana 30 is strong enough to be locked and the 'best' selectable locker is an ARB Air Locker. After that would be the Eaton E-Locker. It is the Dana 35 rear axle that should not be locked. If you're running 35's and wheel on tough trails, stronger alloy shafts for the front axle should be high on your list of next upgrades.

A lot of what I read was people bitching about upgrading axels before locking any stock because they would easily snap. What makes the d30 more widely locked than the d35? I figured the 35 would be stronger in the first place

The D30 doesn't see the same amount of load that the D35 sees. Ive got the D30 locked...running 35s...on stock shafts...and have yet to see a broken shaft on some pretty hard wheeling.

In reality, if your statement about everyone swapping axles (front) was true...what would be the replacement? If the guys you are reading about say "swap in a rubi axle," they must not be aware that the rubi 44 is the same axle as the D30 from the differential out.

I read about upgraded d44s, HP30s or the end all cure all d60. I'm just asking because honestly, I don't know much about drivetrains. I was just trying to help this guy out because no one replied to his thread lol

It all depends on what you are upgrading. On a D30 or a Rubi44, the first thing to fail will be the ujoint or the ears on the shafts that hold the ujoint. With chromo shafts in either, you are much better off, but this isnt a requirement to lock it. You can always put in different 44s...sometimes aftermarket...sometimes junkyard axles...but this can come with a hefty price or custom fab skills. The same goes for the D60.

In reality it all comes down to what you plan on doing to and with the rig. If you plan on running 40s...then obviously the D30 isnt for you. However, if you plan on running 33s locked...the d30 is just fine. The d30 can even handle 35s on stock shafts depending on the type of wheeling you do. Like I said in my previous post, my stock d30 has held up to some pretty tough wheeling...but I am taking a gamble every time I push it. If I were to upgrade the shafts, I would not be worried at all.

Because the front axle seldom sees more than about 50% of the loading the rear axle regularly gets.

another vote for ARB...however I would not order it.. have the shop doing the install provide the locker.. that way if something goes wrong you can fall back on them. Make sure they have installed a ton of them and ask how many have come back with issues...

Wherever you can get the best deal different vendors may have different specials going on.

This is also a good idea. It does provide you with a little insurance.
