front spindle nut torque

Tapered roller bearings need preload. You need to tighten the nut with the tire and wheel on while turning and pounding on the sidewall at the same time. This will act to seat the bearings. Continue to tighten the nut until you can see and feel a noticable drag on the wheel. Do NOT back the nut off. This is incorrect procedure. You need to tighten to the next available slot and put the cotter pin in. Without preload a tapered roller bearing will not bear its load properly.
