How do you go about changing the oil seals where the drive shafts go into the gearbox on your peugeot 306?

To change the oil seals where the drive shafts enter the gearbox on a Peugeot 306, start by safely lifting and supporting the vehicle. Remove the drive shafts by first disconnecting them from the hubs and then pulling them out of the gearbox. Use a seal puller to carefully remove the old oil seals from the gearbox, and then clean the area before installing new seals. Finally, reinsert the drive shafts, ensuring they are securely fastened, and check for leaks after refilling the gearbox with oil.
