Wheel Nuts Description

All models use metric wheel nuts and wheel studs. 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.
The thread size of the metric wheel nuts and wheel studs are M 12 x 1.5. This signifies:
^ M = Metric
^ 12 = Diameter in millimeters
^ 1.5 = Millimeters per thread

If a broken stud is found, Refer to Front Suspension or Drive Axle for the replacement procedure.
