Locker Install
I have a 97' F-250 5.8 4×4 and I have grown tired of the open differential in the rear. It is axel code 35 and I would like to install spartan lockers or something similar. My question is, "If I were to install lockers in the rear would I be ablessed to engage and disengage the locked rear similar to the front axel?". I live in New Hampshire and my driveway is a quarter mile long all up hill, so I would like to use thus truck to ploe. The open differential has made this very difficult.

Yeah open diffs are friggen useless in the snow belt.. I really miss my LS equipped 4x4. If you get an auto locker for the rear you don't have to do anything it will always be locked when you are on the throttle and will unlock when you coast and turn at the same time.

Automatic lockers (like Spartan, LockRight, Detroit, etc) can not be unlocked like a front axle. However they will automatically unlock any time you are going around a corner, even if you are are on the gas. They will relock when you go straight again, or if you spin the inside tire (a lot of people think that if you are on the gas they won't unlock, so they scuff tires going around a corner, but that isn't how they work).
I've had automatic lockers in the rear of three different trucks. My CJ5 saw a fair amount of winter driving, and my F-150 was my daily driver through 9 Minnesota winters. You will notice them, in both good and bad ways. But overall I think they have better winter manners than a factory limited slip (and are much more effective as well).

Lockers don't operate using friction, so no friction modifiers are needed.

I have a Spartan locker in the rear of my Jeep, it works great. I filled the diff with 85w140 gear oil and the locker hardly makes any noise.
