You make sure to double-check that. Swapping in a Explorer 8.8 isn't that bad if you don't have a 31 spline so don't worry about it too much. lifted97 is normally right tho

 

so, what is my door jamb supposed to read if i have a 31 spline axle? is there anything else i can check. i know i have a 2002 Fx4 with all the goods, but im...once again, clueless

 

It will give you a certain code for what axle you have, once you have that just go look in the thread posted and it will tell you what axle you have and what gearing everything.

 

and another thing, i bought my truck used...so i dont know what somebody could have done to it before i bought it. i got it from a legit dealer. but the previous owner could have jacked the good parts and replaced it with crap. OR i just worry to damn much.

im sure someone knows what i mean. lol

 

I highly doubt that, it's always a possibility though. Theres a metal tag on the axle so if you want to double check you can do that.

 

there were two metal tags (on the diff, right???)

one tag read to what i could make out*
V313A
L10 88 2DO3
^ not sure if it was a zero or an o the other one said something, but didnt pay attention because it wasnt a code.

 

I'm pretty sure that means you have a 8.8 with 4.10 LS but I don't know about the spline count.

 

Check the door jam, I can't read that Spanish.

 

On the 2nd line the first group is the gearing and then the 2nd group is the axle size I don't know about the third tho.

 

whats a door jam. i new to this whole vehicle thing! man, i need some knowledge.

 

Open the drivers side door. Look where the door latches to the loop thing. There is a sticker there. The sticker says a lot of stuff in codes and words. Look for the word axle there will be a code beneath it. Look at the chart in the link I posted it should be in some format like that.

 

Yours will probably say R7

 

i feel like an idiot! lol yea, i saw the sticker. it says R7 i dont know which axle its talking about. or if its a 31 spline. and i hope i still have the original axle for the truck. and when i bought the truck, it did have some different rear fender. its an all metal one, kinda looks like an after market towing bumper. i swear, if my truck has been in a wreck and they failed to mention that. i will **************************************

and do i need a new axle for the OX locker???

 

I'm not an expert. I think you're going to have to get some special kit because you already have a lsd and in order to put a locker in there you might have to. If there is a good reputable off-road shop near you you might want to head on over there and talk to them about lockers and your truck. I don't mean 4 wheel parts (one near me is rude and doesn't like talking much or answering questions) but a mom and pop type place. Out here in the desert we have a bunch but only a few are really good and know their stuff. Good Luck man

 

sounds good. and thanks a lot to everyone that stuck with me and helped me out! i cant thank you guys enough

 

I was thinking about runnig aussie lockers in the front with manual hubs and rear diff. What do you guys think about that and how hard is it to install in the front? I don't have big tires.

 

how much do you know about doing this kind of stuff?

it took me and a friend (who had never installed a locker) a few hours. hardest part is really just getting the diff out of the truck.

all you need to make sure you have is torque specs and a torque wrench

 

Wow there is alot of bad info in this thread im guna clear up a few things .

First the ARB is a Air powered selectable locker they only make them to fit in the rear axle not the front , Yes there is a switch you mount inside the cab to operate it
Pro its a durable selectable locker
Con its 800+ by itself throw in the compreser and install kits and your over 1300

2nd The Ox is a cable activated locker probally the best selectable locker made
Pros its cable activated so it will always work no you cant break the cable if its routed along the frame as per Manufactures instructions , Its indastructable ,
Cons its 849 plus the cost of the cable around 90 extra

Eaton is a electric locker also selectable from a switch inside the cabe
Pros it would be the cheapest option but still of high quality .
cons - Its electric wich dosnt mix well with the elements , if something fails its very hard to diagnose problems .

Next your axle is the 31 spline so your good to go on all three , above do not try to install this your self not to make fun of you but you seem new to this and as you stated you dont have a clue this is something that can cause alot of damage if done wrong , I wouldnt even do this myself and ive been around trucks and 4x4 since I could walk.

My advice you dont seem like you wheel much if it was me I would just get the rear OX locker and if you got into any problems where you decide you want more then get the front locked , As from what I gather of your posts you dont wheel enough to warrent fully locking . But its something you can due in the future if needed , take the money from the front locker and invest in some good off road lights and recovery gear youll be btter off for now .

Me im a 2wd Im guna lock the rear and put a Mile marker 8000 lb winch (just incase) and make it anywhere I need to go if this gives you any idea of what a locker will do .

 

everyone says you need a compressor..

you dont NEED it. it just makes it easier if you plan on switching it a lot
