1994 Walter Hürlimann examined the 4x4 transferbox of the Vectra/Cavalier/Calibra after a Customer complain. He discovered that the cause for the complain was the piston of the separation clutch and searched for a solution. The solution was the development of a changed piston, but the manufacturer of the transferbox was
skeptical. But it worked, the transferbox was working well after the repair. The rate of complains about the transferbox raised, and so Water Hürlimann specialized himself for repairing the Opel 4x4 transferbox.
His huge knowledge Walter Hürlimann gave to his sons, Reto and Marcel Hürlimann.
