Planning to change gears on my 2007 JK 2dr Sport (same as X). It's with auto trans and 33s. I think I'll go with Superior 4.88 so that I can put 34s or 35s tires in future.

Please advise me on the installation kit! I really know nothing about it, but I want everything to work smoothly after the install.

Thanks in advance for your assistance!

 

Hire a professional.

 

I would buy the overhaul kit..

its a lot of labor to re-use old parts

 

I will hire a professional for the install, but since I am in Russia and will need to order everything from US, I need to know what to order. Then I'll give all this stuff to a pro for installation.
I just need to know what to order: installation kit or overhault kit or both? What kits are the best? By which manufacturer?

Sorry for all these questions and thanks for your help!!

 

Why? If he can turn a wrench with any semblance of reason, and is really motivated to learn he could do this job no problem...to this day I still don't understand the hype changing gears seems to produce...it's very perpetual in nature, noone wants to believe that a backyard weekend grease monkey can accomplish changing their own gears...and properly

There are a ton of great resources online that anyone can google and sift through....and I am by no means an expert, nor am I a mechanic but I have tried to compile as much info as I could in a write up of my own...it's at least a decent place to start to figure things out.

it's an '07? Get the overhaul kit!
The difference between the install and overhaul kit is, the install gives you the bare bones to install the ring and pinion but you have to use your old bearings, not a bad idea if your installing ring and pinion in something less than a year old in my opinion....but since your ripping them open to do this job, why not just take care of everything all at once to ensure a long happy life with your new gears, get the overhaul kit which includes new pinion and carrier bearings. As for manufacturer, there really isn't many out there to choose from, I personally reccomend anything with Timken bearings in it, but thats just me.

By the way, what your looking to make sure you have in the kits is. New ring gear bolts, pinion depth shims, carrier shims, crush sleeve, pinion nut, pinion bearings, and carrier bearings.

 

I believe many if not most (as in, something over 51%) of "weekend grease monkeys" underestimate the technical requirements in a gearset swap and overestimate their own abilities to perform one.

 

Does that include me? To what do you base this opinion on...or is it just an opinion. 5000 miles off and on road on mine and going strong.
If someone can understand the procedure I believe they can do it, but if after reading a few different instructions a few times your still scratching your head and have doubts than maybe you shouldn't tackle it, or at least have a compitent individual assist

 

I can't include you mate, I don't know you from Adam. I'm simply making a generalization.

I'm not saying it can't be done by a competent hobbyist providing he has time, temperament and tools; still, I tend to think it's more than the average owner should take on.

 

Thanks everybody for your feedback!! I really appreciate it!
I will order an overhaul kit!
