Hello, since my two axle cuffs are broken at the front of the wheel and I wanted to change them the days. Is there anything to consider or tips and tricks you should know about the four wheel, with feathers in front? Does someone have a good guide or a video? But I think that the W164 is equal to the W251. I found some videos on YT. But if someone still has an important tip or trick, I am always grateful. Thanks
