I have a 92 f150 and the axle code on the door jam is 19. correct me if i'm wrong but I heard that was the 3.55 non-limitedslip? also hows the non-limited slip work?

 

I am not sure about that ticker but to find out what gears you have, look on your rear end cover. Attached to one of the bolts there should be a metal tag with numbers on it.

If your truck is the same as mine, you have 355 gears on an 8.8 rear end.

As for limited slip, I could explain but someone has already typed it out for me - Limited-slip differential - Wikipedia, the free encyclopedia

Read the 'Benefits' section.

 

Its 3.55 non ls

3.55 Open

 

An 'open' or 'non-limited-slip' differential means that you have what I call "one wheel drive"--that is, only one wheel will spin when you really need more traction.

All power goes to the first tire to lose traction.. which = useless.. start shopping for an LS.

 

I'm gonna ask the obvious: if this is useless, and I agree it is, what good or purpose did it serve? And why not just get rid of it altogether? Seems like it had to be around for some reason or another

 

Well, a differential is necessary on non-slippery surfaces (where 99.999% of all driving takes place), and an open differential is the simplest system. Limited slip, locked and other non-open differentials add traction at the expense of reliability and, well, added expense. In some cases, they can also cause handling problems on some surfaces (such as locked differentials on ice).

Eff that! Full power both wheels all the time and STOMP ON IT! I think if everyone did that, the world would be a happier place

 

so let me get this straight, if i'm in 4WD and i get stuck in the mud or snow and am spinning, only the wheel not getting traction will spin? in 4wd would only one still spin?

 

In front both will have power. Front= locked. Back will not change in 4WD

 

1 front wheel and 1 back wheel its actually only 2wd when in 4wd

 

so will the power go to the wheel without traction on the front axle too? thats no good for mudding, ****! lol

 

Yep always takes the path of least resistance install an ls you will never regrat it

 

Nope, most of these trucks have open diffs in the front too so only one wheel pulling there.
