The title says it all. My HDJ81 has the oem part time T-case and oem lock out hubs. I assumed the hubs they used on the 80 series were the same as the 60 series and bought a new one, (chinese). Anyway after a bearing rebuild I can't get the C-clip to seat properly. Maybe not the hub at all but thought I'd check with you guys. I've got it stripped down again now I'll report back..
