Need your help.
Basic information: Car is 2000 Mazda MPV, and in the process of replacing the alternator, I found that when the dealership replaced the bad alternator (that was the second one, both the original and second one last 7 years each, I am working on the 3rd alternator). They re-used the single-use axle nut. The axle nut needs to be dented at a notch on the end of the shaft. So the dealership "rotated" the nut beyond the original dent about 30 degrees to make a new dent. In the process of torquing the new (my own) axle nut, I find that it takes only 15-degrees to go from contact to 175 ft-lbf of torque (175 is the spec). Additional 30-degree rotation could mean the bearing is extremely preloaded. The rotor now has visible run-out.
Question for the B&B on this board is that: what do I do now? Should I torque to whatever to reduce runout? what if the runout does not reduce even I torque further? Thanks.
