A sign that the clutch release bearing needs to be replaced is increased noise when the clutch pedal is pressed, and a leak of working fluid from the clutch release drive slave cylinder indicates the need to replace it.
NOTE: When replacing the clutch release bearing due to noise, check the condition of the drive disc pressure spring petals. If the petal ends are heavily worn where they contact the bearing, replace the drive disc assembly.
Clutch release bearing A is a single unit with slave cylinder B, secured with three bolts to the inner wall of the clutch housing.
1, Remove the gearbox (see "Removal and installation of a manual gearbox",), unless it was removed for clutch repair.

The bearing should move to the stop without jamming and clearly return to its original position with the pressure spring.

6. Replace the clutch release bearing seal ring regardless of its condition.
7. Install the clutch release drive slave cylinder assembly with the bearing in the reverse order of removal. Tighten the slave cylinder mounting bolts to the clutch housing to 7 N·m.
