2014 Touareg 3.0 TDI - Front Differential Grind 150kmiles

Front diff went out last month, slowly started to grind. My fault not replacing the fluid, I run her pretty hard and have towed my trailer prob 20k miles. I found a donor Audi that Ebay said would be compatible, it sure fit, but the gear ratio has to be off. I thought we had it licked, ran smooth a few days normal commuting, but at high speed (accelerating past 80mph) or climbing a hill the 4motion engages and it shutters. Does anyone know where to find the bearings to rebuild it...the bad bearing is behind the conical spiral just off the main drive shaft. First problem would be how to remove it, seems like it's part of the main housing, my press would crack the housing if I went after it. I've seen some good write ups here on rebuilding the early model year differentials, haven't seen it on T3. Part is $3500 new or shipped used from Germany / Slovakia $1500. 😫

What’s the part number on your original front diff, and on this one? What engine is it from? If the ratios are wrong you’ll damage your centre diff very quickly. For now I would remove your front driveshaft until you can repair it properly. Otherwise you’ll be replacing your transfercase too.
