Install or Overhaul Kit Needed?
Hello all, not new to the forum (mostly reading and researching) but new to posting. So here's the deal, I just recently won a 2011 Jeep Rubicon Unlimited (Auto) while I was deployed to Iraq. I have been wasting no time trying to build on it. In the next week im going to be adding 35's (35x12.5r17) and a 4" Rough Country X-Series lift. My question is, I have 4.10 gears and have read in the fourms that 4.10 will work with 35's (possibly with some loss of power), if I were to regear to 5.13 or 5.38, with my Jeep being a newer model (recieved it in late March) would I still need to purchase a install or overhaul kit or would that be a bit overkill? Would it be safe with just purchasing an install kit alone? Any help would be greatly appreciated. Thanks

You got a FREE Jeep. Why cheap out and re-use bearings? Get overhaul kits, have gussets welded in at the same time, and you could even consider adding sleeves while the axle is ripped apart.

Brand new with 0 miles? I'd think you'll be fine with just the install kit. No need to replace the bearings if they're new.
5.13's will be adequate with the auto, but go 5.38 if you ever plan on going >35"
4" is more than enough to clear the 35's too. You'll be fine if you put on heavier bumpers/tire carrier. If not, re-consider 2.5-3"

I would go with 5.13s...plenty of gear for 35s.

Dont forget to factor in new driveshafts with that amount of lift as well. Cause you're gonna need them sooner or later. And possibly adj control arms too. If you just want 35" tires I'd stick with a 2.5-3" lift. A 3.5" lift with flat fenders will clear 37's

What mileage would it become necessary when regearing to get an Overhaul kit? I too plan on regearing soon with new 35's and 2.5 tf coil lift on my 2011 Rubi with only 1900 miles on her.

There is no set mileage number, they are a wear and tear item so obviously more miles = more chance of damage. But less miles doesn't necessarily mean they are good.
How proficient is your installer? Will he run into any issues? Will the bearings be damaged when he removes them? Will he have to remove and install multiple times to get your gears set up right? Will they be damaged the second or third or fourth time they are removed? Replaced? Would you rather he do the setup with the current bearings and 'know' that your new bearings are good, or hope...
Anyway, no set mileage, just a judgement call. Talk it over with your installer and decide what you want to do.
