lockers questions

hey all with the recent weather events in michigan i am considering installing a locker in my jeep. thinking just the front for now. the question is what kind. i do have a limited budget so the most effective for the least price is best. it is also my DD so i dont want it to kill my mileage. if i understand how lockers work putting one in the front axle for now wont hurt my mileage or affect handling that much. am i right in my thinking? was looking at a 27 spline aussie locker on east coast gear supply i know very little about lockers so i would appreciate some input. i am sure a lot of people are looking for a similar setup, a locked front axle the doesnt affect drivability too much. thanks

p.s. heres the one i was considering lemme know what you think!

I've heard a lot of people recommend Aussie and lock rite lockers for the front diff if on a budget. As long as you still have the CAD, that locker will be invisible when in two wheel drive.

You'll love the difference and never go back to an open diff

I'm in Michigan, and I run an Aussie locker and love it, but I park my jeep in the winter. You'd be fine as long as you don't run it in 4wd on the street. A locked front on snowy roads would be scary.

If your plan is to add lockers because snow and ice, you're going about things all wrong. Lockers are not good in ice or snow covered roads, deep snow off road maybe. Since the inside tire takes a shorter track through a turn, if the wheels are locked it has to break traction, this can cause real problems on the road. An open diff is much better on ice and snow, an LSD is as close as I would get to a locker for street driving. Because my jeep sees snow and ice I'm going to a selectable locker front and rear(ARB), it will be off on snowy or icy roads.

What Reno said. The locker is not good for on road use with snow. It will be very squirrelly in turns while in 4 wheel. If it's an ice and snow thing, better tires are probably what will help you the most.

Either way there is no replacement for slow careful driving in snow. Give yourself plenty of braking distance. Remember, 4 wheel drive only helps you go it does not help you stop.

Limited slip is much better and safer on a snow / ice conditioned road than a locker. I would consider either a Detroit tru trac gear driven limited slip or go with the ECTED electric limited slip / locker.

Been driving my Jeep in all kinds of snow conditions lately. Locked with an Aussie in the front for well over a year and it's perfectly fine. I prefer the front locked in the snow actually. Yeah, if you are trying to turn and have the gas floored, it will want to go straight. You have to have common sense. As long as you are a half decent and smart driver in the snow, you will have absolutely no issues.

I know its money you may not have, but consider a selectable locker up front. Especially if you have the front axle passenger side disconnect live all the time, or have it eliminated with solid shafts or something. A live locked front axle gives you a lot of undeisrable front end behavior for a daily driver. Its a wonderful upgrade for a trail rig, but not for a DD. also, as stated, lockers aren't that much of an upgrade for snowy driving. I had locked the back on my old YJ, while it was still a DD, with a detroit. Figuring i'd just live with the negatives. You ca most certainly live with it, you can learn how to drive a locked axle in the snow, but its definitely not for everyone. I did fine, i had a few cases where I wished i had that open diff again (or a limited slip maybe), but i never had any major issues (like, accident causing ones) due to it. Just something to be aware of before you drop the money.

i appreciate all the input. the reason im considering locking is that i live in an area where it takes days after it snow for the county to plow the roads. i would most likley not be using 4wd once i get to the more traveled roads if you will.

Under those conditions locking may come in handy, when I lived in the Sierra's we measured the snowfall in feet not inches and lowering our tire pressure to ride on top of the snow and locking the diffs was a normal part of getting to the plowed highway. Now I'm in San Diego and the only time I see snow like that is when I'm going boarding or going over the mountains to play in the desert. Just be careful when you get to the plowed roads, lockers can be tricky.

^^^ this. Common sense goes a very...very long way over just thinking you can tackle anything cause you are in 4wd and "locked".

Just be aware, that 4wd or not, locking the front has negative side effects. Even if 4wd is not engaged, your front end will behave differently after its locked.

Not with the CAD, not engaged, then it's just an open diff.!

No, its a locked diff with one axle shaft broken in half. ;-)

Point taken, I wasn't thinking about the axle disconnect.

CAD or not, an auto locker in the front axle will behave just like an open diff when in 2wd (except for the slight ratcheting sounds you might hear). They only lock when torque is applied to the differential (4wd).

On the other hand, a selectable locker switched on, a spool, or welded spider gears on a front axle without a CAD will most certainly affect how the Jeep handles whether in 2 or 4 wheel drive.
