Shimano HG free hub body on a set of DT Swiss rims. I’m on my 3rd cassette in as many years and wondering if it’s worth replacing my free hub body yet?
How jacked is my free hub body?

Normal wear and tear. Just use a bit of grease on the splines and you’ll be good.
Sounds good when you spin it the bit marks generally I see with steel cassettes on aluminum free hubs for some reason just put a thin layer of grease and keep rolling.
This is normal wear. However, it might be time to service the bearings and ratchet if you haven’t done that in three years. Nice free hub and nice rims will serve you for a long time.
Is crazy to me how often people worry about the nicks on the outside when they have no idea how in need the inside is of service. Pawls/ratchet/bearings…
You could replace it, but that’s probably overkill. Just get it serviced, as far as the wear on the splines goes, just some grease as others have stated.
Unless it’s slipping, its still good.
Well, eventually you’ll start having a hard time getting cassettes on and off this FH. So, if you want to avoid that, replace it.
What we do at the shop is use a pin and hammer to gently smack the cassette/cogs off the bike, then we take a bastard file to the free hub splines to get rid of the burled metal. It works fine, and you should get a few more years out of the FH.
Note, once you start removing material from the freehub, you’ll really want to make sure you are bringing the lock ring to torque when installing a cassette.
from the markings, this is a ebike! you’re using the turbo pretty often and don’t shift much, just powering off the line in the higher gears. you could get more life out of your chain and cassette if you shifted into more appropriate (lighter)gears before coming to a stop! on the bio powered bikes, the splines are usually chewed up on the larger, slower (lighter to get up the mountain) sprockets, because there is more power going into them, than on the faster, smaller sprockets!
