Strange Locker Question

To better facilitate our once-monthly moderate off-roading, I'm beginning to think lockers may be in order for our relatively stock '11 JK Sport. However, as the demand will never meet the my justification for the cost of selectable lockers (especially on both axles), I had a fleeting thought. Has anyone ever installed lunchbox lockers in both axles, only to replace the open gears for winter driving safety? I'm wondering if a few hours' of my labor every other season wouldn't offset the cost, given it would be less than 1/4 in price. Just wondering.

Change center section every year? Jack/hoist Jeep, drain diff, remove wheels, remove brakes, remove axle shafts (don't damage seal), open cover, remove bearing caps, pry out diff, set aside shims and races, deep gears means removing ring from carrier to get at center section (don't damage bearings while doing that), disassemble center carrier section (open gears or locker, reassemble center carrier section (open gears or locker), install ring gear with loctite and torque (without damaging/fouling bearings), spread case, install carrier/races, install shims, install bearing caps, release spreader, torque bearing caps, do final checks/cleaning, seal cover, install shafts (again don't damage seal), install brakes, install wheels, oil diff, jack down and you're done the rear...

...yeah, that's practical... lol.

I think get a lunchbox for the rear and a selectable for the front and be done with it....and, are you even sure with mild wheeling you need a front at all? I would say I use my front for every 10 times I use my rear locker...

Far too much work. It is not worth it.

I havn't actually wheeled my 13', however on my YJ the front lunchbox locker gets me about anywhere I want to go. Probably best $300 i've spent on my Jeep.

That or the winch....

Instead of a locker have you given any thought to just putting a True Trac LSD into both ends? That's a good set up for dealing with PA snow in the winter and would work for your occasional mild to moderate wheeling, for about the same cost as 1 selectable

Thanks, all, for your insightful replies. I should have known it was too good to be true. I just got caught up in the hype someone was making that a lunchbox could be installed in 10 minutes. Snake oil doctor, most likely.

I don't think the lunchbox in the rear would work out in the winter, as the wife drives it occasionally. I think I might look into the LSD route. Additionally, a buddy is a corporate exec of a company that owns a plethora of auto parts stores and junkyards. I'll see if he can pull some strings and get me high on the request list for a totaled late-model, low-mileage Rubi. A guy can dream, right?

Thanks again, all.

Before I put a locker upfront in a "mild" "mostly stock" "once-monthly offroader", I think I would just go with an ARB, OX, or some other selectable locker in the rear and be done. I rarely use my front locker in my rubicon - it makes steering a pain and in most cases you don't need it anyways...

A rear locker and good tires will do more for you than just about anything else you can do to your jeep.

^^ Good advice. What about an eLocker to avoid the manual activator issues I've seen for ARB and OX...or am I thinking of something else?

In the 11 miles into Rubicon Springs I am locked rear at least 20 times - but fronts only once or twice... only use front in straight climbs unless rear doesn't get it - most of the roughest stuff needs turning where front lockers just don't wanna go....

I thought I might add that Yukon makes an air locker that is very similar to ARB but a costs a few hundred dollars less.

I had one installed in the rear of my Sahara a while back after the factory limited slip came apart. I like it so much that I am contemplating getting one for the front while weighing other upgrade options.

I cannot see your profile from my phone. Before lockers get a good winch. How often do you need to get recovered and a front locker would have let you make it?

When you wheel is it mostly mild trails, rocks, lots of steep hill climbs? I typically use the fronts for big climbs and some rock gardens. If I use them in mud the odds are greater than 70% I'm not going to make it anyway and will need to winch.

If your plans include bigger tires and a re-gear do lockers at the same time as the gears to save on labor costs.

Thank you. My style of wheeling tends to be mud, mild-to-moderate rocks, and hills. I'm beginning to sway more towards the rear selectable locker. No, I probably will not regear, as I will not be increasing tire size beyond 33" and will most likely retain the 3:73s.
