New Guy, New to me Jeep - A few Questions

Pic first, just cause.



Just grabbed up my first jeep on Monday and I have a few questions about gearing.
  • 2001 Sport (Has a decal on the side that you can barely see in the pic that says Dakota)
  • 4.0L I6
  • 3 Speed Automatic
  • Lifted (Dealer said it was a factory lift, but I didn't know they existed, and I'm not quite sure how tall it is)
  • BFG Goodrich 35x12.5" Tires (A bit big as I will get to later, but they were brand spanking new and I got a good price on the whole package)
  • Gear Ratio I'm unsure about. Some paperwork said 3.73 and some 3.07 - I'm getting 11 mpg with the 35's and it’s noticeably sluggish on hills so it may be the 3.07.
  • Dana 30 front
  • Dana 44 on the rear

I've been doing a bunch of reading on here, and it looks like I will probably be fine keeping the tires with a 30 on the front and a 44 on the back. (The consensus seems to be that 30's break in the same places as upgraded axels and it's probably best to keep it till it breaks) I don't have any intention of doing hardcore off-roading just want to avoid getting stuck when out hunting/fishing/camping. However, I really need to re-gear. Anyone here have opinions on what I should gear to? I would like to still make 70 on the freeway, but I suppose that 65 would be bearable. I'd like to get some numbers from those of you with 4.56's and 4.88. Top speed, RPM's at speed, Miles per gallon.

The other question concerns mechanics. Who should I get to make the gear change? Find a dealer or go to a local mechanic? I probably have most of the tools aside from pullers and such to do the job, but I lack the necessary back knowledge. My mechanics skills only extend to changing clutches in 30 year old JD tractors with someone looking over my shoulder. I rarely touch cars and really don't want to mess things up.


Thanks guys, I know bits of this have been covered other places, and I've gleaned a lot - but haven't been able to find all the answers with the search button.

Welcome.

Few answers for you"

1. No factory lift for your jeep. Post some pics of the underside and we can give you a better idea of what you have.. but in general to fit 35's figure 4-5" of lift.
2. axle are fine for 35's.. Gears.. most auto came with 3.07s however with the dana 44 you might have 3.73's
3. Try to find a local shop to install new gears.. I want to say with auto.. 4.56's. Also is the speedo adjusted for the tire size?

That's all I have for now.. folks with more info will chime in .... nice looking jeep.

Thanks for the answers - I didn't think there was such a thing as a factory lift. The jeep's a 60th anniversary edition, so that kinda had me confused at the dealership. I'm guessing the Dakota decal was added later as well. And no, the speedo reads 5 mph slow - I think the owner had 33" tires on it. Went and snapped a few pics.



Funny faded Dakota decal....

Looks like a 4'' lift with doetech shocks bud. By the design of the front swaybar disconnect I'd say it was almost certian a teraflex 4'' lift kit.
Front trac bar was redrilled on the axle side and moved over to recenter the axle.

As for the sticker...most likely a club or wheeling group the previous owner was a part of.

Ok. I thought the front axles were D35. Which have a rubber plug, according to what I learned from you. But the front axles are usually D30? I sent you a pm earlier.

OH YEAH...localfiend...Welcome to the forum bud.

If you would like to know what esle is under your jeep take some pictures of the rear of the t-case, the control arms and the skidplates under your jeep and we'll tell you if you have anything nice bolted up under there.

Don't think I've ever heard of a D35 up front.

Here's a link to a gear chart (click here) that I've always used. 4.56 would work, but with 35's I might even bump it up to 4.88's.

If you regear, you'll want to also pick up a new speedo gear for your t-case. Here's a link (click here) to a howto. Swapping out the speedo is incredibly easy...there is only one bolt involved. If you gear to 4.56 you'll wanna pick up a 37 tooth speedo (part number 52067637) and if you gear to 4.88 you'll want a 39 tooth speedo (part number 52067639). Last time I picked one up it ran me $13 at the local Jeep dealer. I've heard the prices have gone up, but haven't confirmed it.

Thanks for the welcome guys and for the info. I have one pic of the underside, I'll try and get some more of the other stuff and some better angles tomorrow.

Doesn't show much but the massive plate:


And a pic of the Dana 44, which has a slightly leaky plug.



I'm gonna try and take a pressure washer to everything on the underside when I get the chance - so I can see what if anything else is leaking - No drips on the pavement so I don't think its that serious.

Also the leak on the rear axle appears to just be comming from the fill plug. Probally spilled a little when checked or filled up.

To find out your factory gear ratio just look at the tag on your rear diff at the 9'oclock position the gear ration will be stamped on the tag...

Attach and circled in RED is the tag where you can find the ratio...

Cool, I had to run out there with a flashlight and check. Looks like it's a 3.73 which makes me feel a lot better - Was worried those tires would damage the transmission before I can get it re-geared. It's still probably not that good for it, but I feel better anyway.

Good to know what the lift is as well, this forum is a wealth of knowledge - woulda taken me forever to figure this stuff out myself. Tried searching those numbers on the D44 a few days ago and come up with nothing, helps to know what you're looking for. So the suspension has a 4" lift, how do I tell where the body is lifted if it is at all? If you can't tell, I'm quite new to jeeps.

Thanks distortedtj

Missed this post somehow. That chart is very helpful - and I can see what you mean - the 4.88 is probably a better fit - though they're both pretty close. I'll have to go and take a look at the speedo gear, and see whats on it now - might give me a better idea of how the jeep was setup previously.

When I do re-gear anyone have a prefered brand?

Thanks

No body lift on your jeep bud.

Body lift is easily identified by the space between the frame and the tub. In the first picture you posted at the top of the page you can see you have the stock body pucks at the rear of the tub where it meets the frame. So, no body lift on your jeep bud.

If you regear have the shop you take it to doing the regear order the gears. If you purchase the gears yourself and take them to the shop, 99% of the time the shop WILL NOT warrenty the parts.

I like Superior Gears, Yukon is good too.

Ok, I see what you're talking about. And judging from the way things look, it's not something I'm going to have to worry about either - tires seem to have plenty of clearance just sitting, guess if I ever do any offroading I'll find out if its enough.

Good point - I definitely want a warranty on them - one of the reasons I don't think I'd want to do it myself.

If you have never done gears or have the knowledge of setting up gears. Do not do them yourself. It take time to learn how to set up gears and not just something the average do it yourselfer should preform.

Highly suggest having a shop set up the gears if you are not trained to do so.

Yup, I'm gonna have a shop do the work, learning more has convinced me of it. I have the knowledge to take it all apart safely, but putting it back together right might be a problem.

Not trying to hijack the thread, but just a question for Distorted. How can you tell that is a teraflex control arm on the rear? Are they the only ones shaped like that. I'm asking cause I bought a jeep bout two months ago that is already lifted and control arms look just like locals. any info is apprieciated.

Tera flex is the ONLY company that made that style of Disconnects.

Teraflex also is only one of 2 companies to make control arm in that design.
Alot of companies and shops sell Teraflex lifts with Doetech shocks as kits.
All adds up together.


Post some good pictures of your suspension, control arms, springs, shocks, and all else. We'll let you know what you got bud.
