I have a powerlock in my Duster, and while it is good, there have been times during burnouts where you could see both tires were not turning exactly the same speed. With the Detroit Locker when you are on the gas both rear tires are going to be turning the exact same speed no matter what! However like Big Perm said sometimes while driving down the road it will unlock and quickly lock back up, when it does this it makes a pretty good "Bang" sound. This is not doing any damage, it is just one of the quirks about it. I myself after owning one for 10 years of everyday driving would not use anything else if given the choice. You are not going to break a Detroit Locker, they are one of the very strongest Diffs out there. Turning corners is not an issue under normal driving, however if you start turning a corner and in mid corner you hit the throttle hard, the diff wind up, locking both tires at the same speed which with the kind of power these trucks have will break traction with both rear tires. Once you get used to it this gets to be a lot of fun. I used to slide my 96 around turns all the time.
