Cube Stereo 140 Hybrid 2020, rear hub failure, Shimano FH-MT510-B

[Craig24]

My rear hub packed up today, the cassette just spins, no drive at all.

Is this something I could repair? Never serviced a rear hub before, or will this be past repair and a full new hub required?

It may just be sticky pawls inside the freehub mechanism. If you can take off the cassette, a good spraying of GT85 into the freehub may free them up. (watch you don't get it all over the disc)
I don't think they can be repaired, if you have the right tools you can replace it but as Shimano stuff has a 2 year warranty on everything except XTR and Dura Ace (3 years), I'd try going back to the shop you bought it from and put in a warranty claim first.

Actually scratch spraying the GT85, there's a good chance that any grease in the hub bearings will get washed out and fail prematurely.

Speak to the shop you got it from first.

Unfortunately I bought the bike used so no warranty . I’ve taken the cassette off, just not sure how to take the free hub body off, on my old bike the hub body just pulled off (Hope hubs).

Sorry, I was looking at the wrong hub!

Here is a link to the dealers manual https://si.shimano.com/api/publish/storage/pdf/en/dm/MBHB001/DM-MBHB001-07-ENG.pdf

Looking at page 15 gives a diagram of the hub.
Try pulling the end cap off on the freehub side, the freehub should then just pull off. You can then clean and re-grease the pawls and ratchet inside the hub

Think this is your bike (2020 140 SL) so it lists all the componenets etc if you need it

Thanks, that’s very helpful, yep that’s the right one. I’ll have a read through the dealers manual and give it a go.
