This vehicle uses metric wheel nuts and wheel studs. The thread size of the metric wheel nuts and studs is M 12 x 1.25. This stands for:

    • M = Metric
    • 12 = Diameter in millimeters
    • 1.25 = Millimeters per thread

The nut will have the word Metric stamped on the face and the stud will have the letter M stamped into the threaded end. The word Metric is stamped on the head of the stud.

If a broken wheel stud is found, refer to Wheel Stud Replacement in Front Suspension or Wheel Stud Replacement in Rear Suspension.
