I've been running a lockright(same thing) in the front of my pulling truck for several years. Many times I've had an extra 1000# on the front bumper while pulling with no problems. Most lockers will hold just fine, but if you loose an axle shaft under power, the locker will usually explode. Now, this being said, unless you are going to truck pull, you won't be breaking any axle shafts. I've even driven the truck alot with the drive flanges on, and never once noticed the lockrite or the detroit in the rear running around town. Its always nice to know that no matter what, both tires on said axle will spin when power is applied no matter what.
Make sure your 70 is tight, and it has not beat out the shims on the ring gear side. This is usually the demise of a high mileage dana 70 in a cummins truck.
