Meritor 09-001668 or 09001668 is a headed, serrated front wheel stud in Grade 8, with a right-hand 1 1/8-16 thread (1 1/8-16 UN-2A), 16 threads per inch and a 1.125 in. thread diameter. Length from under the head is 3 13/32 in., the thread runs 1.81 in., and the head is round, 1.50 in. across and 0.38 in. thick. The stud works like a stiff spring: tightening the nut stretches it slightly, and that tension clamps the wheel to the hub. A genuine Meritor part from Pro Gear and Transmission.
