Freehub (presumably) grinds under load
Long story short, I just got back to cycling recently, after a couple of years on hiatus and storing the bike. I did a general overhaul, cables and housings, all of the bearings, new BB, headset bearings, new brakes, new chain, new cassette, pedals ... I even relaced my rear wheel because two spokes were shot. I basically did preventative tasks.
Now after 200 km it started to show. No matter how hard or easy I drive it, it starts to grind over time, the drivetrain feel is almost like when BB bearings are going bad. But here's the trick, it goes even worse when I'm offroad and stays like it until I clean the freehub with brake cleaner and reoil it. No signs of dirt so I guess it is caused by vibrations.
It goes away for a while after cleaning, you can only feel it on 1, 2, 3 rear, but it goes a lot worse after a trip in every gear possible, altough first three are the worst. Just keeps on repeating.
Few other notes: when I put it in a workstand I can't feel it in my hands. It's there only when you ride it. The cassette does wobble when freewheeling, but the sound is okay, no sticking or weird feel on the drivetrain. Freehub has some axial play that I believe is probably unacceptable.
It's an 8 speed HG40-an cassette on a shimano parallax (nowadays alivio I believe) hub, 11T 8th sprocket, and a relic shimano stx rc rear derailer
From what I remember when I last rode it everything was superb, that's why I liked this bike so much.
I just need your opinion on this issue, because I don't want to go out and buy a new hub if it does not solve my problem. I was just about to put some really nice shoes on it and now it gives me this.
Thanks a lot!
