[quote="Desert Dog"]1) Research the The Magnuson–Moss Warranty Act. You will soon find out that Chrysler has the WORST service in the industry, so get used to arguing for everything. Many of us, including myself, have had to threaten to sue under the The Magnuson–Moss Warranty Act to get work done. Legally, they have to PROVE beyond doubt that a mod you made directly caused the damage. Even if you don't mod your jeep, the dealership will try to get out of it. Unfortunately really bad service and quality is a "Jeep thing". Join a forum like JKOwners.com to learn more about how to deal with this.
2) The Genright aluminum bumpers are good quality. Aluminum is fine for many applications, just make sure you stick with steel for sliders and skid plates. Go minimalist with your bumpers too; many newbs make the mistake of wasting their money on full-width expedition bumpers, only to find out that they destroy your approach and departure angles in the rocks. Stubby, small bumpers are much better.
3) The lift jeep uses is absolute crap and way overpriced. DO NOT believe the hype that your warranty will be voided if you do not use their lift - that is an internet legend, refer to item #1. The dealership does horrible work on installs, ask many of the local shop owners that have to fix their mistakes frequently. If you want to run 35s, just get the Teraflex 2.5" budget boost for a couple hundred dollars and install it in your driveway in a few hours. Bring it by my house with some cold beer and I will even help you install it.
4) Yep, anything under 35" tires looks stupid on a 4-door. And really, the 4-door needs bigger tires to compensate for its poor break-over angle. If you get new wheels, get them with 3.5" of backspacing so your links and tires will clear during full articulation. I highly recommend 17" wheels, as the selection and price are better than with 16" or 18" wheels.
5) And for the stuff you really need, but didn't ask about:
a) Steering stabilizer = get a steering stabilizer relocation kit to move your stabilizer above the tie rod. you will break this on your first off-road trip if you do not move it. The kit is easy to install in under an hour.
b) Front axle reinforcement = the front axle on JKs are really crap. Your Dana 44 is really a D30 with a D44 center section. Yes, Jeep lied to you and your front axle is not really a D44. The tubes on these axles are actually WEAKER than D30s on TJs and XJs. Bottom line; your 4-door is just too damn heavy for this front axle. But the fix is easy, just purchase sleeves and gussets from poly performance and have them installed by a local shop like G&G (G&G has lots of experience doing this). Do this sooner rather than later as I have seen many tubes bend just from hitting potholes on the street. JKO had a run to pismo several years ago where 6 JKs bent there front axle tubes in the first hour of the run. Lots of people in this club have done the same, including me. Also, jeep uses "half clips" in their front axle u-joints on the JK; This is a very poor design that fails frequently and causes other damage when it does. Aftermarket Chrome Moly axle shafts cure this problem and give for much stronger axles.
c) Aftermarket tie rod = the factory tie rod may look big, but it is a very thin hollow tube that bends easily. Once again, these are not up to the task of handling the weight of your Jeep and will bend like a pretzel the first time it hits a rock. Get a Poly performance or Rock Krawler tie rod and never worry about this again. Once again, takes less than an hour to install in your driveway.
35" tires, beefed up front axle, and aftermarket tie rod should get you through 90% of the trails we run with little issues.[/quote]
Ok I have finally start seriously looking into a lot of this stuff. Due to my lack of knowledge and experience I am getting lost on the axle stuff. Sleeves that's easy I found the inner sleeve stuff on poly performance like you said. What gets me is the gussets. The kit they show on poly talks about. Hanging pinion and caster angles for different lifts. Also they show tons of options you can get like c gussets and like 10 other things. And I have no clue what is needed or if it's fluff. I know the angle stuff is for the driveline positioning, with a 2.5-3.5" lift I shouldn't need new drive shafts correct?
Then there are lifts. Teraflex has the budget boost which seems like an awesome inexpensive option. 2.5" but they also have 3" actual lifts and then even a 2.5" long arm kit??? What is the advantages of an actual lift compared to what looks like a 2.5" spacer kit?
As of now I am planning on going to the M&G at G&G Thursday if we don't head out for our trip early. Maybe most of this would better be discussed there? I have monday and Tuesday off also so if someone would want to meet up for lunch or beers and chat for a while about this kind of stuff that would be appreciated.
