There is a better way to protect your investment without using a hammer.
FIRST use the directions on the spinner and engraved directions on the tool.
UNDO right side, turn clockwise towards the front of the car.
UNDO left side, turn counterclockwise towards the front of the car.
TO tighten, turn both sides to the rear of the car.
No matter how tight the spinner are, worn splines may need replacing.
Sizing your spinner? Asked what size tool to order? For a 42-size spinner, measure the diameter of the base, not the eares, will be about 3 1/2". For the larger 52 size Jaguars was about 4".
They don’t have to look like this!
Keep spinners looking new.
