REAR BEARINGS. I just bought a new kit to fix the rear bearings on my dryer but it didn't come

Question

I just bought a new kit to fix the rear bearings on my dryer but it didn't come with instructions. I did find a diagram on line but I can't find instruction. Only thing I am not sure about is where the one little bearing goes and what is the tube of liquid for. By looking at the picture I am sure I can do this. I did figure out how to take everything apart :)matter of fact I am working on another dryer also.I am replacing the blower fan. My husband won't get off the sofa so I really don't want to buy a new dry when I have two that can be fixed. So I am going to do this and show him .
