what gear ratio do you have

[appx91]

3.55 with 35's. soon to be 4.56 with 36's and straight axle in the front.

soon to be 4.56 with 36's and straight axle in the front.

I'd go with 4.88's Troy.

 

[BKennedy]

I'd go with 4.88's Troy.

I'd go with 5.13's for 36" tires.

 

[appx91]

I was wanting to go with some 4.88's but I am pretty sure the D44 I am going with has 4.56 with the Ox locker. I really don't want to have to regear front and rear. I would just have to do the rear if I left it at 4.56.

 

[BKennedy]

You are going to all that trouble and expense of putting in a SAS, then skimping on the gears? Gears are pretty cheap, especially if you already have to regear the rear to match. You are talking about a few hundred bucks for the front gear set.

 

[appx91]

I was quoted at 400. I mean yea I might do it later. But thats the thing I am spending on the money on a SAS. I mean the SAS with the D44 is going to be around 3grand. And then add 400 to that and that would just be like a month or 2 later for the swap. I can always regear both later on. I know I am going no bigger than 4.88. Cause mine is a DD and High Country and I both agree that 5.13 would be a bit extreme for just 36's. Why do you think go 5.13's?

 

[donaldthacker]

I am running 4:10's with 35in nittos. The 4.0 sohc with upgrades pulls the 35's fine

 

[appx91]

That what I was thinking most everyone I know says 4.56 wil be just fine. I think I am going to go with the 4.56. I mean right now mine does fine but is lacking horsepower with the 35 and 3.55. It does fine wheeling just ask anyone who went to Tellico. Thanks man.

 

[BKennedy]

I suggested going with the 5.13's cause that is what I have with my 35" tires. It pulls great on the street, and works awsome in the dirt.

 

[JoshC]

It does fine wheeling just ask anyone who went to Tellico.

Well a couple of times i asked some of the guys if you were in low range because it really sounded like you were in high climbing over those rocks.

What kind of fuel milage are you getting? I have 4.56's on my 35s and have no complaints, i'd just like to have a bit lower. I got about 14, when i drove it daily.

Just personal opinion that i wouldn't go with 5.13's. Of course i've never been in anything that low, so i really don't know how it drives.

 

[appx91]

I get 9.....Yea thats true but I mean it gets the job done...Oh yea the RPM's get up there sometimes thats for sure. What ya think about 4.56 and 36x14.50 thats what i am looking at?

 

[JoshC]

I totally forgot he was going with 36's Brian, sorry!

If you're going with 14.50's also, then you won't get much better then what you have now i'd imagine.

 

[appx91]

Hmmmm. 5.13 thats really low. I am not sure. I think I might just go with 4.88. Do yall guys think it would be that bad with the 36x14.50. Opinions remeber DD and it gets driven every day for school and stuff? I don't really care about the gas mileage I just want SOME of my power back.

 

[BKennedy]

Well, if you went with 35" tires and 4.88's you would be back to near stock gear ratios.

My gas milage sucks, but I wasn't going for milage, I was going for off-road ability. I seem to get about 12-14 miles per gallon on the highway. It wasn't much better before I went big, when I had 4.10's and 32's.

 

[appx91]

So with the 36's and 4.88 and 5.13 what ya think gas mileage would be like. I have air intake and exhaust as far as engine mods. I am looking for it to be good all around and 9 MPG anything could make it better.

 

[BKennedy]

Dude, once you put the big tires on there, nothing is going to help your gas intake. The more you make a vehicle off-road worthy, the worse it is on the street.

 

[appx91]

Well just keep it around the same. I don't want to lose any if possible.

 

[danver39]

I have a '92 ford Explorer 4x4 problems in the automatic front axle not disengaging or making noise in 4 wheel mode i'm thinking about swapping a axle from '91 ford ranger providing the gear ratios match are the axle the same.

 

[DB_1]

Is the noise coming from up front near or at the axle or further back by the T-case? If its up front most likely you have a blown auto hub and you don't need to waste your time swapping in a whole axle.
Do yourself a favor and ditch those auto hubs and get the Warn manual hubs.
Although not bulletproof they are much stronger than stock and even if that isnt the root of your problem its still a good idea to change them out.
You could also have a shift motor problem on your T-case since its not disengaging.
