Shimano FH-R7000 for reference.
I was cleaning my drivetrain and bike, and during disassembly I noticed some play in my hub. I did some troubleshooting by (1) removing the hub, (2) ensuring the shim was present, (3) tightening the hub mounting bolt, and (4) properly adjusting the cups & cones on the axle. The axle was also not bent at all.
When I had the hub removed, I also confirmed play in the hub itself. I do not have the tool to tear down the hub body itself, so my question is how much play is acceptable in the rear hub? Additionally, if this is an unacceptable amount of play, should I replace the rear hub or attempt to tear it down by buying a new tool?
How much hub play is acceptable?

i say it’s a bit to much. was it always like this?
It’s on the way out. Not awful, but it’s only going one way.
check if the lockring is still at the proper nm.
maybe send some pictures of the hub itself?
The wheel’s not moving, could it be the freehub?
I’d check if a cassette spacer is needed. If that doesn’t work, you can rule out the cassette itself being the issue. At that point it’s either the free hub body, or the entire hub itself
Are you missing a spacer?
Have you remembered to put any spacers back in? Because no, that much play is not great.
Definitely hub and not cassette. You may be able to tighten the system down but it won’t be possible with the cassette on.
Thanks everyone for the help 🙏 The freehub is definitely the issue and I’ve purchased a new freehub to install soon.
As it stands, the shifting is still smooth but I would prefer not to have to deal with rough shifting (or worse) during one of my 50km commutes. Cheers!
Something is def wrong. Looks like the lock ring isnt putting pressure on the cassette. Missing a spacer, something is compressed, missing an entire gear?
Investigate why lock ring isnt applying enough pressure to hold cassette. Could be something missing on the back side of th cassette.
Looks borderline to me. With that being a pretty cheap hub I wouldn’t be surprised if it came that way.
Do you have any shifting issues? I’d just take it to a shop and get their opinion.
