My 🙂 found that my all-wheel is defective. The cardan shaft does not turn. it probably means that the angular gearbox will be. Cost point approx. 1800,- euro. I used to screw myself and am thinking about doing it myself. I could get a WG at EBAY, 40,000 km, price approx. 700,- euro. Now I need the part number if the gearbox also fits. Where do I get this number.?? Maybe there is also the one or other tip if I d Doing it yourself?? Thank you so much and another nice Sunday. Greetings MickeyReiner
