adawg38 Do the gearing brotha! It's like $1200 for parts and labor and you'll be happy. To get good clearance with them tires I'd do a 3.25"-4" Lift. I did the 3.25" and they'll clear 32's no prob.

Sticks You definitely got a flatland Jeep. I have yet to check to see what my wife's axle ratio is, but it seemed to do OK in 6th when the 32s were on (got a second set of wheels and put stock size tires on for the non-white season).

I don't know of any shops in Denver other than Bear Frame and Axle that could do a gear swap. Maybe Drive Train Industries in Aurora. If you do decide to change the gearing, may as well get a set of lockers while you are at it. Don't want to have to do it twice - go big or go home.

Me - STAY AWAY FROM BIG-O on Arapahoe & (east of Peoria). Not real bright over there.

kbaum03 Nice jeep. Your options appear pretty clear. Stick with the larger tires and upgrade your axle ratio or sell your current tires and go back to a 30 inch tire or smaller. Looks like the cost is close with the axle swap a little more expensive.

It's not the parts that are expensive, it's the labor.......

pakman55 glad we could help....im also glad your 4x4 works.

Ichthus Thank you by the way (TO EVERYBODY) for all your opinions, advice, and help! I have learned a lot the past 24 hrs!

I expect that I will be doing a lot of going to shops and talking with the mechanics to find out their experiences with gear swaps in jeeps before I make my final decision.

3.07 with 32s just isn't cutting it for me on the hwy. And LOL! there is no way I will go smaller in tire size. I like the look with what it has now and is perfect for the easy wheeling I would be doing anyways. Just need some more power to keep the higher speeds on the road.

InfernoGirl You're better off letting the shop get the parts for gears. Then if something goes wrong, they can't blame it on the parts you supplied, and charge you labor again to fix it with another part..... If you really hate your gearing move down to a smaller tire, if you can't afford to regear properly. I have 33's with 3:07's but mines an auto, for what I use it for and my terrain, it's not a problem, but I can see how you'd hate a manual in CO with them....
07-28-2010 09:01 AM
Ichthus Ok so now I know what I need to do gearing wise. I'm gonna find a shop (hopefully) that can just do the install and I'll buy the parts (possibly used) from somewhere else.

So now on to the lift. I still don't think I have a lift, so here's a pic of my coil and my side underbody. Pretty sure there is no body lift. Don't think there is a suspension lift.

What do you think?
07-27-2010 10:01 PM
adawg38 I didn't know that they came with 3:07. Yeah I'm in Westminster. I'd definately go 4:10's and if you want a little bigger down the road go 4:56. I am gettin some 32's by end of summer and going 4:10 and gonna upgrade my axle shafts. I've also been told if you stick with the D35 don't go 33's with a locker or on the trails you can snap your shafts so you may think about upgrading them also.

For sure, it's a 3.07, I checked the tags on the differentials. I also read somewhere that some 06's came with 3.07 depending on the package that was bought.

The 06 2.4L came with 3.73 to compensate for engine size.

P.S. I see you're from around here too!

Unfortunately I don't... I've only been here about a year, and only had my jeep about 2 months. I do most work myself unless its something complex and needs specialty tools that I don't have. I tend to stay away from those shops because usually all they wanna do is up sell you on things you don't need, and I hate that. So I usually use this forum to answer any questions I may have. One thing I do for mechanical advise is go to like Big O, and ask if there is anyone that knows jeeps well, I have done that a couple times and they are usually friendly and very willing to help if they truly are a Jeeper.

I will say my D35 doesn't look like that. 4:10 is what u want on 32's like people say but 3:73 does me good with 31's. That 6th gear is pretty much useless I've found.

The only one I know of up here is High Country and my guess is they are popular and expensive. Just a guess though, I need to talk with them still!

No problem, from what I have read, pay someone to do it. But shop around, I got quotes from 3 different places and the cheapest I found was 250 an axle for labor, and I think its around 250 for ring and pinion. So it was around 1000 with parts and labor.

If I move to 4.10, will my 6th gear gain more power to hold the high speed (75mph) on the highway and even be able to accelerate?
First congratulations on the new Jeep! second 3.07 on 32's is your problem with speed... I have an 04 5spd with 3.07, and in 5th gear if there is any type of incline I drastically lose speed, same as you. I only have 31's but yes if you re gear to 4.10 it will help with highway speeds and you'll get your 6th gear back. Lastly, where in denver are you? I'm in monument (20 minutes north of the springs)
07-27-2010 08:57 PM
EdJonesJeeper P.S you might can find some used 4.10 gears for pretty cheap out of some old 4banger wranglers.
07-27-2010 08:57 PM
Ichthus I won't ever go more than 32" tires for sure!

So maybe I would be over-doing it a little with 4.10. What would you recommend?

First Welcome to WF!
3.07 is a common gear ration but unfortunately it's the worse they came with. 3.73 is what I have with the 5spd manual and my 33's bog me down still pretty good. If 32's are the biggest you want to go 4.10 probably max I would do. I'm not real familiar with the gearing of the 6spd but this thread might help.

http://www.wranglerforum.com/f5/tj-t...ecs-26347.html

Your 6th gear is a little lower than my 5th so you should be good. I plan on going 4.56 b/c I want 35's one day!

07-27-2010 07:23 PM
Ichthus Ok so I'm gonna say it's a 3.07. Would this make any sense?

Yesterday I noticed that doing 75 mph and throwing it into 6th I lose speed.

I am more concerned about highway driving than I am about off-roading. I don't do a lot of off-roading at all and when I do, it's very light.
07-27-2010 07:14 PM
adkjoe It doesn't look like your diffs have ever been opened especially since the tag is there and your 4wd works so yes both will be the same ratio.

The front should have the same tag look for that one to.
07-27-2010 07:08 PM
Ichthus That is exactly why I didn't like my 4WD! It was hoppy when I was turning tightly left or right. I thought that's why (dry pavement) but just wanted to make sure from other people. My explorer never did this.

And OMG I didn't see that silver tag on the bolts until I posted the pic. I couldn't see it with my bare eyes but with the camera flash it shows up. Grrrr! I will get that number right after dinner! Thanks for helping! Oh also! So since my 4WD works it's safe to assume that both front and rear are the same ratios??? So whatever the silver tag in the rear says it is, that's what the front is too?
07-27-2010 07:01 PM
adkjoe The tag is right there in your photo vertical attached to the two side bolts on your rear diff. It's black, clean it up and read the x.xx number of off it. That's a dana 30 in the front and a dana 35 in the rear

You probably don't like your 4wd because you used it on dry pavement so it was probably hopping wasn't it?
07-27-2010 06:36 PM
Ichthus My 4WD definitely works - found some things I don't like about it but will discuss later.

So on to my gearing and suspension...

There are no tags on my differential covers.

Here is a pic of front and rear (in that order)
07-27-2010 06:34 PM
Ichthus So here's my Jeep...
07-27-2010 05:27 PM
Bignuke If your not sure, don't put it in 4x4 because it could cause some major problems... Check the tags on the diff covers, if they are removed, you should go to your 4x4 shop.
