The ball bearings on my Miele are shot. I’m in the process of replacing them with new ones. In some videos I’ve seen people lubricant the ball bearing where it touches the shaft. Is this necessary? If so what lubricant should I buy? Secondly are there any other liquids I need? Sealant for example. Thanks in advance. via /r/DIY http://bit.ly/2IydUHr
