i mean whats this about torquing and backing off
If you just torque wheel bearings down they will expand, bind up, and cause your hubs to overheat when you get up to highway speeds. They should be torqued to 50 lb-ft to seat the bearings and then backed off and locked down. You should actually end up with a very small amount of end play when complete. I found a measurement somewhere of what the endplay should be, but I can't remember where i found it or how much it should be now.
Ultimately, they are very forgiving and will tolerate quite a bit of variation. Hence the torque to 50 lb-ft and back off until you can lock it in place, not to exceed 90 degrees of back off. This should get you within the end play spec without actually having to check the end play. When the vehicle gets up to speed everything warms up and expands and the end play disappears.
