When doing a clutch job, dont overlook the release bearing. Your vehicles release bearing (also known as a throw out or clutch release bearing) is a cylindrical thrust bearing that is used for engaging and disengaging the clutch. Throwout bearings wear out, and if yours goes bad, replacing it takes the same amount of labor as the original clutch job. ACT provides quality that lasts, materials that work, and processes that perform to ensure calculated results.
