Dana 44 - lunchbox okay?
I'm about to swap out my XJ's Dana 35 for a factory XJ Dana 44. It's coming with 4.10s and an open diff, so I'm inclined to pick up a lunchbox locker (thinking Powertrax) due to cost and not having to set anything up (just slip in the Powertrax and go play). Is this a bad idea? I'm only running 32s and most I'd ever go up to would be 35s. Everywhere I've gone, the flexy suspension of the jeep makes it through with open/open, but want some added security of at least one axle locked up. My thought being if I add a locker to the 44, it's the strongest (stronger than the HP30) and gets most of the weight going uphill. By keeping the front (HP30) open, I don't stress the (760 full c-clip) u-joints or stock axles.

That will be fine the Powertrax no slip is expensive. I have and recommend Spartan lockers, I also installed one in my friend's Dodge 1500 Dana 44 front axle and it has been working great. Aussie also makes good lunchbox lockers. This is probably going to start an argument but in my opinion if you are only going to lock one axle then the rear is the way to go, that way you have the extra traction all the time not just in 4x4. My rear locker is hardly noticeable on the street other than you don't spin out as much as you do an open diff.

Spartan = $270 So about $110 difference. The reason I was looking at the Powertrax is everyone raves about how "nice" it is on the street (quite/easy to drive/etc.). How's the Spartan on the street? I'm all for saving $110 if it's not a major difference. |
The Spartan is hardly noticeable at all, if I turn the radio off and coast around a corner I can hear a faint clicking noise, but you can only hear it if you listen for it. I let other people drive my Jeep and they don't even notice it has lockers.

I don't think there is any functional difference between any of the current generation lunchbox lockers, save the Spartan coming with a better crosspin.
I have Aussie, Lokka, and Spartan on hand, you would never know you were driving one vs another... Too bad I quit my last job, because I wanted to send an Aussie and Lokka in for XRF and Brinell testing. |
The noise isn't the issue from the diff. It's the way they act that can be disconcerting.

That's the most frustrating part of all this research. Some people say locking diffs never act up (even in snow and rain) while others say they are near undrivable (in snow and rain). TO ME, I'm inclined to think they are drivable (but just need a level of caution).

Both my Jeep and F250 have rear lockers, and I daily drive them both without issue.

I don't have lunch box lockers in a D44 yet, but I have the axles and lockers and they will be going in. Currently have LOKKAs front and rear with no problems now for 5 years. And I wheel hard. See Avatar for proof

LOKKA? That's a new one I haven't heard of before. Is it a full locker or just a lunchbox? How does it compare to the other lockers?

I've been DD'ing one for what's pushing 25 yrs now......in a few different vehicles with different power levels/tire sizes...never had any issues with them being quirky or giving me fits like some say they do. Couple of things to consider...... 1) Your driving habits will dictate some of the 'issues' others complain of 2) Quality of installation will dictate some of the issues others complain of If you don't follow the directions and check & recheck all the clearances, or use overly worn parts (thrust washers/spacers on some axles), or don't use a hardened center pin, you can & will have issues. The thing needs a certain amount of clearance to work, and too little to or much will let it do stuff it ain't supposed to do. I've used lockright & spartan....both work equally well, but the spartan is easier to install I think due to the way it is made. |
