I have a Schwinn Pathway 18speed bike. I put about 60 miles a week on it, over the past 1.5 years. Recently I noticed a clunk in the rear wheel. All gears and only while pedaling. I cleaned it up and replaced the chain. same problem. put old chain back on, same. I noticed there is some bearing play in the freehub bearings side to side, like the bearings are loose or worn. The axle bearings are fine. I would like to remove the freehub and bearings to check, clean and relube. How do I remove the freehub? it appears to have an outer lock ring with notches on the outside. See pic.
Thank you in advance,
