This - here’s a better photo from the interwebsWhere is it cracked? I see the indents in the drive ring to help give the pawls clearance when reinstalling the freehub body, but I don't see any cracks.

Just pulled the cassette to clean and grease the hub and I don't like what I see. View attachment 211546
There's probably a limit to loaded up with grease if one wants pawls to fully engage.I had two mechanics at my LBS look at it closely. Lights, camera, zoom and we all determined those are not cracks but rather machining marks. We saw no signs of any cracks when looking closely at the teeth. Weird, I've serviced this hub many times and never really noticed those marks. It's back together, loaded up with grease so it's nice and quiet. I'll pull it apart in another month for a check up, unless it starts to self destruct sooner, I'm still a little concerned. Also waiting to see what I9 has to say when they see the pictures I sent.
Could be, if you pack it full. On my Summer Wheels I like a little Phil grease + Tenacious oil to quiet things down.There's probably a limit to loaded up with grease if one wants pawls to fully engage.
I'm going to agree with your mechanics and referencing @JonFern 's picture. The marks are from the machining operations. Too uniform in depth, width, and equal spacing radially between each set around the circumference.I had two mechanics at my LBS look at it closely.

I believe they recommend the Dumonde Tech Freehub oil. There is also a very light grease that is recommended if you want quieter pawls. Forget what it is. I'll have to find it on my bench.I'm going to agree with your mechanics and referencing @JonFern 's picture. The marks are from the machining operations.

Too much grease will make it quiet, but may hinder engagement. I9s are supposed to be loud. Probably not as loud as the Hope SS specific hub on my SS. What does I9 recommend for lubing the freehub?

LBssssssss$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$ - But I agree.
Seconds on Whites and also Hadleys. No longer an I9 fanboy either.If you want pretty colors/something not everyone has, get a pair of White Industries.
I've seen the latest and greatest DTswiss falling apart a lot recently.Wood never buy just based on cost noise maintenance and every post about them being a PIA from actual users. DTSwiss and Shimano FTW.
and get off my lawn!
I have a 2nd-hand wheelset with I9 hubs that have not given any trouble, and I recently greased the pawls too. Plus, there will never be any Shimano on my bikes, been that way for 34 years.Wood never buy just based on cost noise maintenance and every post about them being a PIA from actual users.

If you look in the svc manual, those machined relief sections allow the pawls to slide back into place upon reassembly. I had my i9 rear hub apart 1 week ago for normal service and it looked exactly the same. Ride on. BTW-My fav hubs are King!I had two mechanics at my LBS look at it closely.

So basically this thread falsely made I9 hubs look bad?I had two mechanics at my LBS look at it closely. Lights, camera, zoom and we all determined those are not cracks but rather machining marks.

Brand New and it's all cracked like that? WTF 🤯
