Hello together, since since the last wheel change from summer to winter it is constantly poltert on the rear axle, I took off the winter tires today and put the summer tires on it again. 2 out of 4 screws were deeper than the others after the assembly OK, wheel down again and then saw that. 2 holes are basically almost through, it seems as if one has worked the holes afterwards with a sink drill For me now the question is where this comes from. a) I ha be the tires always changed themselves and with the prescribed torque of 130 NM attracted by OZ according to the report b) in 07/2012 the vehicle was during the inspection. – There was a brake fluid change. Do the wheels have to go down? – Cable wheel speed sensor back left was suspended. Do the wheels have to put down to mount that again? The original wheels have to be tightened with 140 NM!? If it comes from the dealer, it will surely be impossible for him since Thank you for the relevant information.
