I rebuilt my rear hub for a single speed that I am putting together and might have lost a part. I re-lubed everything and put the bearings back in but now I am unsure if I have all of the pieces to tighten up the axle. Right now I have the bearing cone in there as you can see in the picture. My question is, do I put the white cap and then the lock ring or am a missing a part in between. When I tried to tighten it back together it was clamping down the bearings and was not able to spin correctly. Anyone have an answer?
