locking the rear

[XJJK]

went out to calico over the weekend and discovered the factory LSD has a very liberal definition of "limited slip." (tracloc in D44)
so now I'm trying to find my options to lock it up.
My first thought was an aussie or spartan to match the aussie in front, but then I'd need to buy an open carrier and any savings from the lunchbox setup go out the window.
I also want to upgrade to 4.56s at some point... meaning I'd also need a new carrier in that case as well, correct?
I'm thinking that means my only option is to go the ARB/OX type locker route.
Thanks for your input.

Richmond Gear (PowerTrax) makes a lunchbox locker that fits in the TracLoc case (check to see if it would fit in your application, it's the powertrax version, not the more agressive lock right):

I haven't this particular locker, so I can't give an opinion, but this guy has:

hey, thanks Eric. I will check that out.

I thought I saw a aussie locker add on pirate for $199 and a new open carrier is ~$60. Compared to $453 for the powertax unit. I also read the tracloc housing isn't very strong but not sure on that. You could always rebuild your tracloc also set it up tighter.

thanks, I will see if I can find that on pirate. I don't want to bother rebuilding the lsd.

Is your front locked already?

Reason I ask is because, it may be wise to buy a lockright/spartan for the front and leave the rear as a limited.

I run mine this way, and use the e-brake to force the rear to "lock". Have only ran into two spots since locking the front where I found that a full rear locker would help.

I do plan on fully locking the rear, just waiting for a deal on a used full case locker, like a detroit/grizzly.

[XJJK]

yes, I have an aussie in front. up until now I have never failed to clear an obstacle... I didn't know the trick with the hand brake. how does that work?

[2blk2drs]

in an open differential, all torque is transferred to the wheel with the least amount of grip. Pulling the brake adds friction, and sends some torque to the other wheel.

Also you might try running your lsd without any additive. I run straight gear oil in mine and it locks up better than I ever expected it to.

[XJJK]

oh, ok. I wonder if mine is even working. the po didn't maintain squat.

[Jeeperator]

I think they should of called them unlimited slip lol. Actually mine still worked decent with 125,000 miles on it. But its nothing compared to my new detroit.

I’m locked in the front and open in the rear. It really helps to have the locker in the front but it puts a lot of torque load on the front axle. If I get into a situation where I have a tire up on the front AND the rear all of the torque load will be on one axle shaft. I am hoping to put a locker in my rear soon too. I think it will save me some axle shafts in front.

ah, nope. not true
with any diff, locked Lsd or open torque is always split 50/50. torque is not a constant, but is developed according to what is demanded by the load. so if a open diff has one wheel on a rock demanding 50 pounds of torque to turn and one in the sand requiring 10 pounds to turn it will develop it will only develop 20 pounds of torque, 10 on each side and when the side that is in the sand turns no more torque is required so it quits developing torque and the stuck wheel will not turn, what a LSD does is when both tires do nit turn then it applies friction to the side turning until 100 pounds are developed and it both turn. Lockers are locked so it always would develop what the stuck side needs. Now knowing this we can use a hand brake or feather feet the brake to put braking friction on a LSD and it kicks in faster.

[OU812]

That is an excellent way explaining it. Much simpler than I could have attempted to describe it. Thank you.

What about a trutrac worm gear lsd? Its supposed to put more torque or power to the tire with the most traction. I am not sure it always works that way though.

it does not put more torque to one tire, they are split 50/50. Always, you cannot get around that. it applies friction on the axle not turning till the amount of torque to turn it equals the torque of the stuck tire, so they both turn. however that being diffacult to explain in short advertising space, they say it transfer torque.
