Noob..
OK. Some Noob Differential Questions here.. Never really messed with em and now I want to. I wanna stick a locker setup on the truck. I do know that I have a Ford 8.8 non limited slip diff in the back (rear axle code 19). What kind of axle do I have in the front of the 1990 Ford F150 4x4? Also what is the best locker setup in your mind to place on a truck for good street use as well as some good time offroading on occasion. Also what I do to the rear I have to do to the front to keep things even right. I know that is the case for gearing but what about lockers. Like I said I have never dug into a differential before and I am gonna try my hand at it.

your front axle is a Dana 44 TTB. and yes for gears the same should be done front and rear, for lockers, no, no reason to. because you drive mainly on street. i would suggest a limited slip over a locker. but if you decide a locker is a must. i suggest a selectable locker over automatic. take a look at detroit.

Ok I was thinking from what I had found the front end was a dana 44 but I wasnt to sure so I thought I would ask to make sure. Also I was swaying the idea of the limited slip around as well, but then I seen the detroit that you are talking about and it said something about being able to drive on the road fairly well with it installed and that got me thinking. Do you know of a good limited slip I can look for? Just to compare and read up some more on? Thanks for the help.

If your going to do street driving and some off road, than a stock LSD will be just fine. My Mustang GT has the 8.8 with stock LSD and it has held everything I've thrown at it. To the point that the pinion bearing gave out before the LSD went. Now if your going to be running big tires, doing burn outs, and going crazy off road then I don't think the stock LSD will last long.
IMHO a stock unit should be fine.

well I am running 35's at the moment but I dont think I will be burning them as they cost way to much money to be doing that. .haha. But I plan on playing in the mud a bit here and there as I live out in the sticks and have some tempting mud holes not to far from the house that I wanna get into and have just played around the edges since I myself dont think the setup that I have will pull me outta the middle at the moment.
And yes Hitokori I have no idea what I am talking about when it comes to diffs because like I said I am fairly new to all this and starting my expensive hobby with this truck. haha. And expensive it is getting to be. Just ask my wife. haha. I am just looking for the best setup for the money.

i think im with Buck on this, for mild offroading and mainly running on the street. you may find it more effective and cheaper to pick up a stock unit from a junkyard.
if you have your mind set on a locker, check out OX lockers, Detroit, and ARB are the more prominent names, there is also a locker (i cant remember the name) that is a limited slip when not locked, they are expensive(once i recall the name i will post it).
but be sure to get a selectable locker, i dont think to highly of auto lockers. bad experiences.
but so i have an idea, what is your truck? model/year and any upgrades?

1990 ford f150 4x4 lariat
351 w efi
8.8 rear
crap mazda 5 speed soon to be changed out to zf 5 speed.
no upgrades yet except for susp and motor swap to 351.
looking to totally make this truck over and want to do it right.
sounds like I might just go with a limited slip as I want some street performance as well

As for finding a LSD in the junkyard, good luck. I don't think Ford made a boat load of LSD F150s. Everyone I've run across has had an open diff.
You can buy a new LSD for around $290 to fit the 8.8 if you are unable to locate one for your truck in the junkyard.
Good luck with your project

the name of the limited slip/locker is the Auburn Ected. it it an electronic Locker but when disengaged acts as a limited slip. though expensive. starts at around $650. as for finding the LSD in a junk yard i dont know. i dont think they were popular with the pick ups. but i currently have one out of a bronco.
also take a look at some grocery store 4x4 mags, and check out broncograveyard.com (all things ford)

but i suppose its all a matter of preference. i prefer lockers over LSD's simply because i drive off road on a regular basis.
now if the truck was off road only i would say lincoln lock it. but a lincoln look is not fun on road especially in snow.

setting up a rear with a new carrier (as you would if you went with limited slip or a traditional locker) can be expensive and should be done by someone with the knowlege, experience, and speciality tools.
but being you have an open differential, you should look into a "lock right" locker. basically you gut your stock differential, and put this inside. no special setup required and can be done by anyone with decent mechancal abilities. i have one in my F350. its been in there for 4 years and i have no problems whatsoever - but i never do burnouts and run 33" tires. i installed it primarily for snowplowing. i go gentle on my equipment, but it sees it's fair share of work. if your throwing a ton of power at it and doing some aggressive street driving or offroading with big tires, a detriot locker would be your best bet because it is a stronger unit - but between the cost of a detriot unit and a proper install/setup, i'd imagine you'll very easily hit a $1,000.
read up on lock right as part of your research.
