I had rattling warn hubs on my 76. I replaced them with milemarkers. Still rattled. My warn's had rattled for years with no problem.
Mine has the quadra-trac, and I think the hub may be machined just a little differently, since it's supposed to take slugs and not selectables.
What I ended up doing to get rid of the wiggle/rattle is I only installed 1 of the retainer clips. I think I installed the inner, and left the outer ring out. This totally fixed my problem, and everything seems to be working right. I do not, however, know if this was a good idea or not, only that it worked.
Beauty is in the eye of the jeepowner.
