Freehub Body Disintegrate

Recommended Posts

Hub: Shimano Deore XT M785

Symptoms: Chain suck & wobbly cassette

Anyone any idea why this would ever happen and what to do to prevent from happening again.

What hubs are they? I have been reading that the M775's have an issue with this, I am waiting my turn for this issue...

 

On my M475 hubs I have gone through about 4 or 5 freewheel hubs over the years!

A quick immediate fracture, either a faulty unit or a seriously over tight cassette lock ring.

What bike / wheel was that off?

 

Seen 2 of the same hub do that recently! - Alleged theory is that it is old OEM stock that was not designed to withstand the larger forces of bigger wheels (But in my opinion just rubbish to cover themselves cos they messed up in QC)

Lock ring torque to spec 35 - 40Nm

Any idea who the Shimano distributors are?

I think its Coolheat although you may have to get the LBS where you got the wheels from to do the claim?

Correct on both counts.

Same happened to me! (a while back, though) i took picks of the cracked hub - still posted here on the Hub......mine lasted longer than yours...but still...

 

Seems to be a XT issue...

I read this thread the other day.

 

Yesterday while riding home my cassette came loose.

 

Today I took a closer look..

See the crack through the middle and a piece missing from the side.

 

So now I am off to find a new one. Can I fit a hope freebody onto a shimano hub? Are they compatible with one another or do yo have to replace with a shimano freebody?
