Never use oil or grease on studs or nuts. If
you do, the nuts might come loose. Your wheel
could fall off, causing a serious accident.

with the rounded end of the nuts toward the wheel.
Tighten each nut by hand until the wheel is held
against the hub.
9. Lower the vehicle by attaching the folding wheel
wrench to the jack and turning the wrench
counterclockwise. Lower the jack completely.
