Hello friends, I can not find a solution to my knock problem in shifting from 1st gear to 2nd gear for a long time. I made my last gearbox zero, but I still have a problem. I showed it to a master today, he looked at it in detail and said that it was not a problem with the gearbox that it was caused by a milling cutter on the axle. I researched a bit on the Internet, but there is no sale as a mill, but the complete axle is sold. Does this cutter have a part code? Can we just take it and change it without taking the complete axle?
