Locking it is the precise threshold where the stock axle shafts are put over the limit. Imagine a locked diff and having one front tire in the air and the other one doing all of the work. You give it a tad more gas to get it past whatever obstacle your front tire is on. All power goes to one side of the axle and...*ping* Axle shaft broken. Now imagine the same senario unlocked: the tire in the air gets all of the power because it has the least resistance. This is bad for traction but good for axle shaft life.

Yea I run mtrs and I plan to put in chromolys when I get the cash but fir now what I have seems to work fine

That makes no sense. If a tires is free spinning that is causing almost no stress. It would be like if you had the tires jacked off the ground. The reason a locker can cause more stress is that when both tires start spinning then all of a sudden one grabs a bite, that one shaft takes the force of both tires stopping. If its unlocked and one tire grabs just that tire stops and all the power transfers to the other tire.


I posted this before reading further lol

But 5spdftw is correct

This basically sums it up what I had read a while back....
"locked and throttle control vs. open and a ton of wheel spin everywhere you go"


And I would assume this was also considering a set of chromoly shafts.
