Driveshaft oil seal
1. Chock the rear wheels then jack up the front of the vehicle and support it on axle stands (see "Jacking and vehicle support"). Remove the appropriate front roadwheel.
2. Drain the transmission oil as described in Section 2.
3. Working as described in Chapter 8, free the inner end of the driveshaft from the transmission and place it clear of the seal. There is no need to unscrew the driveshaft retaining nut; the driveshaft can be left secured to the hub. Support the driveshaft, to avoid placing any strain on the driveshaft joints or gaiters.
4. Carefully prise the oil seal out of the transmission, using a large flat-bladed screwdriver (see illustration).
5.4. Use a large flat-bladed screwdriver to prise the driveshaft oil seal out of
5. Remove all traces of dirt from the area around the oil seal aperture, then apply a smear of grease to the outer lip of the new oil seal. Fit the new seal into its aperture and drive it squarely into position until it abuts its locating shoulder. Use a suitable tubular drift (such as a socket) which bears only on the hard outer edge of the seal (see illustration). If the seal was supplied with a plastic protector sleeve, leave this in position until the driveshaft has been refitted.
5.5. ... and tap the new seal into position using a suitable tubular drift
6. Refit the driveshaft as described in Chapter 8.
7. Refill the transmission with the specified type and amount of oil as described in Section 2.
Input shaft oil seal
8. Remove the transmission from the car as described in Section 8.
9. Undo the three bolts securing the clutch release bearing guide sleeve in position and slide the guide off the input shaft along with its O-ring or gasket (as applicable) (see illustration). Recover any relevant thrustwashers which have stuck to the rear of the guide sleeve and refit them to the input shaft.
5.9. Clutch release bearing guide sleeve is retained by three bolts (arrowed)
10. Before fitting a new seal, check the input shaft's seal rubbing surface for signs of burrs, scratches or other damage which may have caused the seal to fail in the first place. It may be possible to polish away minor defects of this sort using fine abrasive paper; however, more serious defects will require the renewal of the input shaft. Ensure that the input shaft is clean and greased to protect the seal lips on refitting.
11. Fit a new O-ring or gasket (as applicable) to the rear of the guide sleeve, then carefully slide the sleeve into position over the input shaft. Refit the retaining bolts and tighten them to the specified torque setting.
12. Refit the transmission to the car as described in Section 8.
Selector shaft oil seal
13. To renew the selector shaft seal, the transmission unit must be dismantled. This task should therefore be entrusted to a Peugeot dealer.
