The FX4 level II 31 spline is easier because the brackets are the same, and come with 4.10 gears. But it has a torsen, so you have to still with that, or have the carrier replaced with an open carrier. Or buy a full carrier locker like a detroit.

The explorer axle normally comes with 3.73's from what I've seen, some have limited slip, some are open. You need you weld on new spring perches and shock mounts. The axle is 1.5" wider and has disc brakes. Search around for axle upgrade info.

The lockrite locker for the 28 spline should be about the same quality as the aussie, but I know aussie is great with warranty replacements and doesn't care what size tires you run.

 

ic. so any idea where i would need to look for an FX4 axle?

 

Junk yard

 

yeah I know, but I couldn't figure out how I wanted to say so I said that way, thanks for clarifying, though.

 

ill have to check. if a truck is junked, how can you find out what kind of rear end it has and what gears? and another question bout the lockers... so uk how when your turnin in 4x4 the tires dont wanna turn, does a locker help that?

 

Wow. No a locker won't help you turn better in 4wd. The front and rear axles spin at different speeds when you turn. If you have to turn sharply take it out of 4wd.

To find out what diff is in there check the door take and compare it to this:



Only FX4 models have the 31 spline axle. Its easier to find an exploder axle.

 

i have 8.8 open 4.10s. ik their easier to find, i just dont wanna hack stuff apart to make it fit. i dont trust myself.i can weld and fab things like skids and deerstands and other stuff like that. but im not gonna trust myself when it comes to something my 9k truck is rollin on. lol

 

I don't know how to weld either. I'd have someone do it. I don't think it would cost too much.

 

nice I'll look around for an fx4 axle. or just get an expo one eventually..

 

same here. might get lucky and find a rolled fx4 like a member on here did

 

I've got the aussie in my Fx4 31spline 8.8 rear...and a manual transmission. And to be honest...I love it. And to be honest...I hate it. WAY awkward to anyone who have not recieved the crash course in driving my truck. Honestly...I'm half tempted to pull it out and run it open until Winter comes back....when i'll actually use it. I can't let just anyone drive the truck...and I hate that.

Also makes any clutch system issues...ALOT more noticeable. There's alot of pushing in the clutch and kickin' the shifter in neutral to unlock the locker in parking lots. It's kind of a pain in the *** even for me. Although...it is ALOT of fun when the roads are wet...controlled drifts!

Like I said..I love it. And I hate it.

I really want to get a selectable locker...one where it's open or limited when unlocked, and a spool when locked.


Might be up for sale soon...PM me if interested. (shameless plug I know. lol)

 

Yea electric lockers or ARB lockers are UBER expensive!! I"d love a selectable in the back of my ranger, its Lincolned lock, try driving in a parking lot LOCKED all the time, lots of people look atcha, but atleast it is predictable!!!

 

So how would the locker im lookin at do then? is it something that would only lock up when only in 4x4 or is it something i have to worry about all the time? and im not too worried about the rear end since i have LS.

 

Are you talkin bout the front axle? Well, I don't know the axles always spin in those whether in 4wd or not.. But, even if in 4wd doesn't mean the front will be locked up, only when it detects a certain RPM difference between the two tires, then it locks up solid.... 4wd or 2wd has no effect on it's lock up

 

It would act just like the rear aussie...but in the front. BUT...there isn't any power being applied to it...it's just spinning with the wheels and ratcheting around corners. People who have the front locker report not even noticing it in 2wd.

 

shuuuuu, good deal i didnt think about that...lol!!

 

Like Shane said, the front aussie locker is like it doesn't exist in 2wd. It just makes a slight ratcheting noise in slow tight corners, can't feel anything though.

stRanger, you are wrong. RPMs have nothing to do with it,.

I know I've said it already, but my rear aussie locker was just fine with an automatic. Never bound up in parking lots of anything like that, it was always smooth.

 

Ahh, I stand corrected then, I'm sorry.... Just though once it 'detected' slip(RPM diff) it would lock up solid... Atleast that's how a detroit has been explained to me and the aussie sounds exactly like a detroit... sorry for the miss-information gentlemen

 

No worries, a lot of people get that wrong because someone told them wrong. They are really super simple units in the way they work.
When I first got the aussie in the mail and opened it up I was like "WTF? That's it?!"

 

LOL!!!! Well I've been workin in baltimore and i had 35hrs OT last week and 14hrs OT this week, so im gonna go ahead and order it.....LOL!! I'm also lookin at a fibergalss cab hieght cap this weekend too for $300.......i'll give you guys update's when i get it and get install pics!! Thanks!!!
