A locker connects the to axle shafts together, an auto locker locks in when in 4wd automaticly using rpm's I believe, an electric locker turns on when you hit the switch same with the air locker, except with an air locker you need air, Duh, so you have to have a tank and compressor hooked up, kinda like the ones the guys use when they slam their trucks, or cars. if you have a 4.10 rear that means it takes the drive gear 4.1 turns in order to make the driven gear turn once

 

oh ( zach ) your front axle should be a dana 35 the same as mine and the rear is an 8.8 not sure about the splines though, I'm going to say its a 31 spline judging by the gearing, might not be right though. go to aussie locker.com and go through the vehicle specs, when it asks you if you want to search by vehicle, then type in your info

 

Powertrax makes then for both open and l/s 28 and 31 spline diffs and ARB makes them for both 28 and 31 spline diffs.

The TTB Rangers have a Dana 35 TTB axle wiich is a revers rotation compared to the 98 and up IFS Dana 35 standard rotation axle.

 

Close, the correct terminology is reverse spiral. Nothing in the diff spins in reverse. High pinion diffs spin in the same direction as low pinion diffs, the only difference is the way the gears are cut

 

I see reverse cut what you mentioned and reverse rotation.

From TRS:

Ford Rangers appeared with a reverse cut Dana 28 TTB (Twin Traction Beam) 4WD front axle in 1983. The Dana 28 was replaced in 1990 with the Dana 35 TTB as Ford introduced the 4.0L engine to replace the 2.9L. The Dana 28 didn't completely go away though. A version of it found its way in to the 1990 - 1997 Ford Aerostar AWD mini-vans. It also found it's way back in to the 4-cylinder (and some 3.0L V6) Ford Rangers from 1993 - 1997. The 1993 - 1997 Rangers can be deceiving. Some owners believe because they have a 1990 or newer Ranger that they have a Dana 35. Although their 1993 - 1997 4-cylinder Ranger may look like it has a Dana 35, it's really a Dana 35 housing using Dana 28 components.

In 1998 the Ford Ranger went to a Dana 35 IFS front axle. The Dana 35 IFS switched from a reverse rotation gear to standard rotation gear. The gears in a 1997 and older Ranger/Explorer will not work in the 1998 and newer Rangers.

You know why this is? It's because the gear teeth are cut in opposite directions of eachother, hence the reverse spiral term. Both diffs rotate in the same direction.

I still stand by my statement.

 

DB_1 is correct

 

I never said you were wrong just saying that not everyone uses the same terminology,

 

No worries...not trying to start a pissing match here
It just seems hi pinion diffs have gotten labeled as reverse rotation which seems like an incorrect way to describe that style of axle.

Anyways, what were we talkin' about here, aussie lockers?

 

I was referring to the gen that we were talking about. I Should have clarified

98+ 4x4 Ford Ranger front differentials do not change regardless of trim or offroad packages.

 

After all this terminology being throw and stuff being thrown around I doubt the OP will actually get a locker in the end. LOL

 

ok, thanks. so now how do ik if i have LS or open or w/e for the rear?

 

Look at your door tag. Then look at:

 

yeah what christian said

 

i already knew i had 4.10s... so your sayin i do have limited?

 

well what is your axel code?

 

97

 

damn, its non LS. so that means its just a one wheel wonder?

 

It will spin both when both tires have equal traction but when that changes you will spin one tire most of the time. Even my l/s can spin one tire.

 

I can't get my LS to spin both tires, even in the wet. Worn out FTL

 

is posi the same as LS? just wondering. kinna aggrivated that its got all the offroad ammenities EXCEPT LS... anyway to change that?

 

Posi and l/s is a different name for the same thing. If you want to change it you can get a locker if you want more offroad traction.

 

ok. so a locker would in a way turn it into a LS? and what kinna price tag does that have?

 

A locker locks the wheels together 100% until you unlock it or you turn (if its a lunchbox locker). A l/s never locks. If you offroad get a locker. Lockers can cost anywhere from $400 to about $1000 after you get done buying parts and paying for install.

 

The aussie lockers run around $250-300. The install is very easy. If you can do a brake job you can install an aussie locker, no kidding.
They are designed to be installed in an open differential.

The aussie lockers automatically lock and unlock. Essentially it is open until you apply a certain amount of torque. As you coast around the locker "ratchets" and differentiates side to side. As you apply a certain amount of torque, the inner gears are pushed out to the axle gears and lock them together at the same speed.

It's kind of hard to explain without using a bunch of pictures or hand motions, but you are sitting at a computer, look it up. There are plenty of explanations, and I think Aussie does a decent job explaining it.
