What size thread is a Subaru Forester wheel stud?
The standard wheel stud size for a Subaru Forester is M12 x 1.5. This means the stud has a diameter of 12 millimeters and a thread pitch of 1.5 millimeters.
Detailed Explanation
The wheel studs on a Subaru Forester are responsible for securely attaching the wheels to the vehicle's hubs. These studs have specific dimensions that must be matched when replacing or servicing the wheels. The M12 x 1.5 size refers to the diameter and thread pitch of the studs.
- M12 indicates the stud diameter is 12 millimeters.
- 1.5 refers to the thread pitch, which is the distance between each thread on the stud. In this case, it is 1.5 millimeters.
Using the correct wheel stud size is crucial for the safety and proper functioning of the Subaru Forester. Incorrect stud sizes can lead to wheel separation, which poses a serious risk of accident and injury. It's important to always consult your owner's manual or a qualified mechanic when servicing or replacing the wheels on your Subaru Forester.
