Upgrade rear end?
Odd thread title now that I read it....
I don't know much about rear differentials and what it takes to change them.
My truck has 373's and no limited slip. I really hate in the winter being a one wheel wonder. Is it possible or economically viable to add a locker or limited slip as after market?

Go with a EATON, i had one in my 6.0L F250 it was awesome and tough it had big fibre clutches in it and i cooldnt wear it out, the other nice thing about it was it was quite no chattering. thats what i would recomend.
I just had Ford put new clutches in my factory limited slip and it still isnt great. the eaton was always posi. im thinkin that might be my next upgrade.. i may just be giving randys ring and pinnion another call.

Why would you need a locker in the front? Isn't the front basically "locked" all the time and that is why it turns so poorly in 4wd?
What is involved with changing out the rear-end? Is that something a fairly mechanically inclined person can do even if they haven't worked with rear differentials before?

Therefore you have simple geometry telling the truck the front wheels have to go faster while the truck's driveline makes this impossible. The result is driveline binding and wheel hop. Doesn't matter whether or not the front diff is open or locked, this effect will always be there.
And, as stated, all Ford 4x4s have an open front differential.

Front axles are open for good reasons: If you've ever driven ACROSS a slippery slope with a front limited slip or locking front axle, you would know what I mean: The downhill wheel has most of the weight; most of the traction and gets most of the drive. The locking front differentials tend to pull you down the hill. The effect is much more manageable with the "posi" rear axles. leave the front as an open unless you have a lot of experience and really think you need it.I don't and I don't..JMHO regards...joe

Well that makes perfect sense, I didn't think about the front wheel speed versus the rear wheels as the reason for the binding / wheel hop. Man if I am not careful, I am going to learn something from all you guys!
