Trailer tow package???

['96explorereddiebauer]

I have the 4.10 Limited-Slip diff and I'm wonder if it comes with a trailer tow package. I don't know because the dealer never told us when we bought it a couple of months ago. BTW, the code on the door jamb is D2. Thanks.

P.S. I guess this is another one of those dumb questions

The only way to get the 4.10 limited slip was to order the trailor tow package, so yes, you have it.

Gerald-

I got the tow package with the 3.73. How can I find out if I have limited slip in the rear? It's a V8 AWD.

Thanks

 

[T-Bone]

Looking on the door, it says axel D4, I'm assuming this is limited slip then?

T-Bone, D4 is the 3.73 L/S. So yes you do have it.

How would I know what gear ratio I have??? I have a 91 Explorer (duh) XLT with the tow package.

Where can I find the info.

Open your driver side door and look at the white label inside. Right above where it says Axle will be a 2 digit code. Post the code here and someone will be able to tell you what ratio you have and whether or not is it limites slip. Two that I know of are D2=4.10 LS, D4=3.73 LS. There are several more.

I don't know much about automobiles, except the basic functions, and maintenance. I may sound stupid, but what is everyone talking about here? I have a tow package on my explorer.

gears

I don't have a door sticker. Is where anyway else for finding the gear ratio?

There is a metal tag on the differential itself, crawl under the truck from the back (on mine, anyway) and you should see it there. I can't remember now if it just has the code, or if it actually shows the gear ratio.

Axle Ratio

I have a 4 door 2 wheel drive automatic 1999 XLS Explorer. The engine seemed to rev pretty high on the interstate. I calculted the axle ratio from the speed and rpm to be 4.1 : 1. The dealer told me that Fords records shom my Explorer was built with a 4:56 : 1 rear axle ratio. I read the axle "code" on the drivers door sticker and it says 4.6.

Can this be right?

Did Ford build plain jane Explorers with 4.56 rear ends?

What option package would this be?

Would this ratio cause my gas mileage to be 15 mpg on the highway?

 

[Rhett]

Axle code 46 is a 3.73 open diff.

Now, if yours says "4.6" I don't know what that means, I've never seen 4 PERIOD 6 before. 4.6 was not put on a sticker by Ford. "46" was.

Axle code Ratio
------------ -------
41 3.27 open
46 3.73 open
D4 3.73 limited-slip
42 4.10 open
D2 4.10 limited-slip
45 3.55 open
43 3.08 open

That is most of the Explorer axle codes.

Anybody ever seen a 3.08 axle ratio Explorer? I think some 2WD models had 3.08 but I have never seen one. Anyone seen a 3.08?

 

[Rhett]

oops. darn. I meant for that axle code thing to look like a table, but it didn't turn out right. o well, I am sure if you see it you know what I meant to do..

 

[leenjen]

i dont know much about gears. what is better, a low number or a higher number?

is one better for gas mileage and the other for acceleration?
what would be better in 1/4 mile, 3.27 or 4.10?
and which is better on highway?


thanks in advance

 

[JDraper]

The lower the ratio, the better your fuel mileage will be, but the worse the acceleration. If you want great 1/4 mile times, you should get a higher ratio. What the # is is a ratio between axle rpm's and driveshaft rpm's. For example, a 3.27 axle ratio means that the rear axle turns 1 revolution for every 3.27 revolutions of the driveshaft.

To answer your questions directly, one ratio is not 'better' than the other. It depends upon what you want the vehicle to do. A 4.10 is better for acceleration and the 1/4 mile. A 3.27 is better for the highway and will give you better gas mileage.

-

thanks jeff. nobody ever explained gear ratios to me before.

 

[Dmann99xls2wd]

Guys - thanks for the info.

My door tag does indeed say "46". Which I now know means my EX was built with a 3.73 open rear end.

My revs on the highway make me think that I have a 4.11 or a 4.56. Does anyone know what rpm my tach would read at 60 or 70 mph in 3rd or 4th gear?? For tires I'm running 265 70 15s which are only slightly taller than stock 235 75 15s.

Thanks

Dan

 

[leenjen]

at 60 mph my tach says just under 2K rpm, but i have 3.27.
3.73 should probably be a little higher, but with larger tires maybe not.

 

[ntrpriz]

At 65, my 2000 SOHC with 3.73 LS is spinning at approx 2100 RPM.

The larger tires should lower that a bit, but not much.

Thanks

3.08 axle Explorer

My '91 Explorer had 3.08 gears, and that was just about the only thing that I didn't like about it. However, my '94 that I use to drive and my '97 Mountaineer V8 have the 3.73 LS 8.8" rear end, and it is definitely more drivable around town and with a trailer. Granted the '91 got better milage, but I've been working on some things, and my '97 is actually getting better milage than the '94.
