Chevrolet Cobalt Service & Repair Manual: Wheel Lug Stud, Replace
| Suspension fasteners are critical
components because they affect performance of vital components and systems
and their failure may result in major service expense. New components must
be installed with the same component numbers or equivalent components, if
replacement is required. Do not use a replacement component of lesser quality
or substitute design. Tightening values must be used as specified during
reassembly to ensure correct retention of these components. |
| Use washers that have an ID that
is larger than the OD of the wheel stud serrations. Use enough washers (approximately
four) to allow the wheel stud to fully seat against the hub flange. |
| Some models may require a suitable
press to remove studs instead of C-Frame and screw Installer/Remover. |

Remove wheel and tire as outlined in
"Wheel, Replace." |

anchor plate, remove anchor plate bolts and position brake caliper
