WHATS GOIN ON, NEW TO THIS WEBSITE, ANYWAY I HAVE A 1996 F150 4X4, I WAS WONDERING HOW COULD I MAKE IT A POSI TRAC? DO I JUST PUT A LOCKER IN IT OR WHAT? I DONT LIKE JUST ONE TIRE SPINNING HAHA ANY INFO PLEASE LET ME KNOW

 

Welcome to FTE
how do you plan on using the truck? There are many options to cure problem. Mini spools are quick and easy to install but not steetable IMO. Automatic lockers are more friendly on the street if your not hauling a lot of weight like towing a trailer, limited slips are better for that.

 

WELL BASICALLY IT WILL BE AN ALL AROUND TRUCK STREET AND OCCASIONAL OFF ROAD

 

Please turn off the caps lock.. it's hard to read.

You want a limited slip diff, and there are several ways you could get one, install a complete LS rear axle from another truck, or change just the differential using either a used LS diff or a new one. You'll have to do some research in your area to see what those options are going to cost, it could vary wildly depending if you are DIY capable or would have a mechanic do it.

 

sorry about the caps being on but yeah thanks man, i am capabale of doing it myself, would you know what year LS diff. i would need or more like what year they came in this is my first gas truck so im new to all this

 

All '87 to '96 f150's used the exact same 8.8 rear axle and the 3.55LS was common so if that's the ratio you have it won't be hard to find a donor.

 

Be careful about junkyard 8.8" axles though. One of the problems with this axle is that the pinion nut likes to back off, which can cause pinion bearing and pinion seal failure. If the axle is leaking gear oil this is almost certainly where and why. If the damage is bad enough you may end up rebuilding the whole thing. Just be careful and make sure you get a good replacement if you end up deciding to swap out the rear axle.

BTW posi-traction is a GM term, we don't use that kind of language around here.

 

I knew I've heard that trash talk somewhere.

 

guys im sorry about the bad language haha really i am like i said though this is my first ford all ive ever really had was chevy diesels, but i understand correct me when im wrong that way i know not to say it hahaha thanks for the info though, also i mean is it wise to get a 8.8 limited slip or should i stay with whats on it i mean whats the pros and cons

 

if it came as a 4x4 it should be a Limited Slip Rearend check your axle code in the door jamb and decode it to see if it is a LS rearend before you spend money on another one

 

Yep. Code H9 would be a LS allready.
It probably just needs to be rebuilt.

 

yep and it is cheaper than buying a axle if you know what you are doing.

 

My 93 4x4 came with a open diff. I installed a Lock-Right about 6 months ago and running 36 inch swampers with no problems......yet. Not the best locker,but price was right at the time and easy to install in your driveway.

 

alright that sounds good so my best bet is to check and see if i have an h9 in my code, and if not that lock-right sounds pretty good as well i will check and let you guys know

 

Yep. if not, it will be a different 2 number code like 19 is 3.55s open diff.
