I'm trying to figure out what on I want to put in my 08 FX4. I have read about the Detroit True Trac and the ARB air locker. What would people of this site do??? I'm going to go with a ARB in the rear just to let everyone know. What are the realistic chances of breaking the carrier/ cv joints with a ARB compared to the True Trac??? I know the IFS suspension is a weak link and you can break it a lot easier than a solid. ARB or True Trac for the front? Thanks again.

 

i wouldnt put a locker in the front thats askin for troubles when your turning with it in 4wd a good ls diff is what you would want IMO

 

Well I was leaning toward a Detroit True Trac but I just wanted to know waht some of the people on here thought. So you think I will be able to go almost anywhere I want to go with a True Trac in the front and a ARB in the rear eh? Thanks again.

 

I would suggest an E- Locker in front. It is always open until you activate it.

Why a E-locker when a ARB is open when it's not on?

 

i would say get the eaton E locker front and rear just so you dont have to have a air compressor and a tank.

but the ARB will work the same.

 

Note: TrueTrac differentials require a certain amount of resistance at the ground in order to start
the power transfer. A TrueTrac differential may not transfer power if the spinning wheel is off the ground. If spinning occurs, often a light application of the brakes, while carefully applying power, will slow the spinning wheel enough to allow the TrueTrac differential to transfer torque to the other wheel. See notes at http://www.eaton.com/ecm/groups/publ.../ct_128482.pdf

Get a selectable locker. When it is on it locks both axles giving 100% torque to both wheels. When it is unlocked it works like an open diff allowing you to turn easier.

 

the problem with any locker in the front is that your cv joints are the weak part in your axle and while they are comparably stronger and offer better operating angles without binding like u joints they still can and when you have a locker it puts more stress on them

while im sure the chances are slim that youll be able to bind up the front end and blow out your front drivetrain would you want to risk it

 

Well how exactly would you "bind up" the front end so much that you could cause breakage in the CV joints? Are you talking about turning under power while the front is locked? Or are you talking about 1 wheel off the ground and the other wheel on the ground grabbing traction while under power? Has anyone destroyed there front ends while wheeling with the front locked on our trucks? I'm just looking for something to keep my front locked when one tire is off or almost off the ground to keep me moving forward. Thanks for the input.

 

when a front end is binding up its the joint be it a u joint or cv joint being pushed beyond its operating range have you ever been in an older truck with the front end locked in and in 4x4 when you turn the front of the truck starts jumpin thats the axle binding up on you

by the sound of it the wheelin your talkin about doin is more climing and trail riding the wheelin i do is goin through the biggest nastiest mudhole you can find and a good way to keep moving is to rock the steering wheel left and right

with just one wheel off the ground and the other on the ground your not gonna get any binding there that will just be torsional stresses on the shaft and joint

but if you think about it while one tire may be off the ground in the front the back two are gonna be on the ground so a locker there is a deff must to help push you through it

 

I wouldnt hesitate at putting what you want in their. With the setup you are wanting you should be able to go just about anywhere you want to go. I have a Detroit locker in the rear and an Auburn ECTED up front. With the Detroit alone i hardly ever use four wheel drive anymore. If i do use it i never lock the front locker. The Detroit makes a world of difference by itself. Which ever brand you run, you will be happy with a solid rear end when you get in the thick of it. Having the capability up front is nice. Plus if i am an idiot and go where i shouldnt, i can recover myself.
