What I'm saying when I say "a little more" is this. When you remove the pinion nut any time for any reason, you mark the nut and the pinion shaft with a corresponding mark. I just use a small chisel and mark the pinion shaft and nut with a mark aligned with each other. Then when retightening, I have a point of reference. I call "a little more" about 5 "or so" degrees past the mark on the pinion shaft with the mark on the nut. Understand? In other words, you could turn the pinion shaft so your mark is at 12 o'clock and tighten the pinion nut until its mark is at about 1 o'clock. Use red locktite.
