2000 Gu Patrol Auto Hubs, My tyre place recommended I nip up my wheel bearings as they were a little loose, all that went well but when I put the hubs back in it what I though was the reverse order I now have dramas, The hubs will work in the lock position and 4wd engaged, but if I have them in the auto selection when I engage 4wd I get a clunking sound, i tried reading my manuals I have here but they aren't much help. any advise would be appreciated
