I don't know much about regearing and wanna learn as much as I can. I have a '14 jku sport, 33" tires blah blah blah....anyways I'm assuming I have 3.21s. From what I read thats the base gearing for a stock jeep.
Now I installed all my parts on my jeep. Lift and all. Question is:
If I bought gears, say 4.11s, is it as easy as taking off the differential cover, pulling out old gears, and putting in the new gears, add some fluid, and done?
Or is more involved? I never saw anything about installation of regears. Is it something I can do in my driveway with basic hand tools? Or is it shop recommended? I installed a 2.5" lift in about 8 hours using jack, stands, and hand tools. I know my way around a vehicle, but couldn't rebuild an engine or anything. Just above average knowledge.
thanks!!

 

Definitely not a novice job...

Unless you are mechanically inclined and have all the tools necessary, find a local shop.

 

Also, you will probably upgrade the wheels so wait with gears until you decide what wheels you will run. Going 4.10 now then going to 35 or 37 will only require a regear again to 4.56/4.88 so don't rush it. You will also need new carriers when regearing from 3.21 as I did. I went with a limited slip rear, some go lockers if they wheel a lot and some replace axles. My point is, wait with regear until you know future plans.

 

I have 17" alloy wheels with 33x12.5 . I have a 2.5" lift. Lost some "oomph" with the wheels/tires.
Added a afe cai and afe scorpion high tuck exhaust and superchips flashpaq to try and get some horsepower back. But still a little sluggish. And I plan on towing a pop up camper within a year or two. So I would like get more power back so I'm not doging down the engine and burning through a tank of gas in 100 miles.

 

I've been wondering about the same thing. I'm running 35's with 3.73s and feel like I lost power. I have been trying to research about regearing and how difficult it may be. All I have found is a couple of videos on youtube but they don't go into much detail and the video quality sucks. Let me know if you get any info on this procedure. Don't know if I'm willing to do it myself yet.

Basic tools like a hammer, a screwdriver and a crescent wrench? Plan on a few trips to harbor freight.

When you decide that this is beyond your abilities, call all of your local shops to get prices, not just one. Ask about the warranty. Ask if they recommend specific brands. Ask if they have different rates or warranties if you supply the gears instead of buying through them. And then try to find local jeepers for opinions and reviews on the shop you like.

Depending on location and specific shop, the prices (and warranties) can vary wildly. Anywhere from $1000 at a few high volume shops (texas and southern california), to $2500-$3000 (mainly east coast and upper northwest from what I have seen posted here). So compare the prices at your local shops to prices at other local shops. What people are paying on the other side of the country is meaningless to you, unless you are going to drive there.

Another possible option, especially if your local shops are at the higher end of the price range, might be to spend some time looking for a set of take-off rubicon axles. They will be more expensive, but will come with 4.10's, electric lockers, and slightly upgraded axle shafts. They are a direct swap for your current axles, just bolt em up, add a switch for the lockers, and sell your current axles. (if you go this route, some of the newer rubicons are coming with 3.73, so verify the gears if the axles are brand new)

 

There is far more involved in setting up gears. You will need specialty tools as well such as dial indicators and a dial torque wrench.

 

Don't take this wrong, but don't try it if your wrenching level/experience is basic. It's not an easy task and it takes more than basic tools.

 

I guess "basic hand tools" was the wrong term to use. I have all the necessary tools to install a lift and do other random things around the house. Probably over a hundred different sockets, extensions, adapters, different size drives. Wrenches and all that fun stuff.
Bottom line, I have more than just a hammer, screwdriver and a crescent wrench. I have a huge 6' craftsman tool chest full of tools.

What I was wondering was if this is a driveway project like a lift installation is. If its a simple procedure. There's not write ups on it from what I've seen, but now I know its more involved if you need meters and what not.
I was hoping it would be as easy as taking off the dif. Cover and swapping out a couple parts, then putting cover back on.
I see its not that easy.
Thanks for the info

As far as pulling the cover and swapping parts, a lunchbox locker can be done in your driveway. Gears and full case lockers, not so much.
