Gear Question
I'm moving up (or down?) to 5.13s and I'm in the process of pricing gears/installation kits. I know someone who has done this before and we're going to change them in the driveway sometime soon. It will probably cost me a 12 pack and a sub.
Anyway, what else do I need other than the gears and installation kits? My X has about 15,000 miles on it...do I need to get new bearings or can I just go with the current ones? Any suggestions or advice on this before I order them? Thanks!

i did the deal through bustabizz on here from 4wd. it was 550 shipped to my door for 5.13's, full install kits (all the bearings, shims, etc), and G2 diff covers front and rear.
That being said. i didn't replace the carrier bearings on mine when i did the gears. but with the free shipping and diff covers, it made sense to do that deal. plus i like having the bearings there in case i need them. i've been suprised when opening up diffs before on wear or problem areas that you don't expect. and good luck getting the right bearings from the local parts store. all their part numbers seem to be f'd... same with the pinion seals. unless you have the timken # off the bearing it seems to be a royal pain.
northridge has a deal with just shims and pinion bearings that i like. i think it's 500 shipped? i can't remember, someone else will chime in.
I know other people have just bought the shims and reused pinion bearings.... personally i wouldn't do that... but it's up to you.

From having put 45,000 miles on my 2009 JK unlimited Rubicon, I've found the gearing should have been 4.56 from the factory with 32" tires (if you had the automatic). It drops out of OD too easy on slight hills.
I'm a fan of replacing the bearings while you are in there. Overall, they are not that expensive and opening up a diff once (whether yourself or paying someone) is always easier to do once.

Okay, I'm changing my order to 5.13s. I guess I was looking for someone to tell me 4.88s were good enough, but that's clearly not going to happen.
Yes, we will be doing the bearings as well.
