A loose or damaged pinion nut or related wear may show up as a clunk when accelerating or letting off the throttle, play at the pinion yoke, or fluid seeping from the pinion seal. These signs can also come from worn bearings, a failed seal or other driveline parts, so diagnose the cause before replacing parts.

Tighten the nut to the torque or preload value in the vehicle service information. Follow that procedure on whether a pinion nut may be reused.
