The kit includes one pinion nut and one matching washer, and it secures the pinion yoke onto the pinion shaft in the differential. It is typically replaced when performing pinion seal replacements or other differential repairs that require removing the yoke, as reusing the original nut can compromise proper preload and torque retention. Using a new nut and washer helps maintain correct alignment and prevents driveline vibration or damage.
