On the showa forks, there are 3 screws that hold on the fork guard, at the bottom axle lug. Over tighten or use screws from the disc guard, a little longer, it caves in the very bottom of the fork tube that screws into the lug. The spring hangs up on it, and makes the forks feel ruff. Them tubes are not cheep! And just like the pinch bolts, it does not take very much more torque, to really cause some damage. If you clean the holes out, with a light you can determine if they are damaged. Normally you should be looking at the same basic size as the fork tube, and a very fine thread. Damage starts when the screw gouges the thread, then will appear as a dimple at its worst. The bushings are an inspection service, if it shows a wear pattern, replace them quick!
