I found the threads on the Aisen manual hubs and that enabled me to remove and replace my bearings and seals, but upon reinstalling the hubs I have a problem nobody has addressed. I have the whole assembly together and installed all the way to the cap, but the cap will not mount up to the housing no matter what I do. I figure I am overlooking something, being unfamiliar with how these things operate. The link from one of the threads helped, but I am still not getting the cap to mount flush. It seems to be stopped by something about 1/4 inch or less from the housing and will not go any farther. What do I need to adjust or realign and how do I do it to get this ligned up properly?
