Is my hub stuffed if...

[New Landy new life]

I assume I am correct in calling the hub the part where my rear wheel gear cluster is bolted to.

 

Anyways....

 

I am getting a "clack" sound when pulling away in the rear cluster and when I freewheel for any length and try to pedal, I spin a few revs until I get traction alsmost like the ratchet in the gear cluste hub is not engaging.

 

My drive train is all new, gear cluster, front sprockets and chain - only the hub was not changed.

 

Can someone confirm my suspician that the hub needs changing.

 

The bearings seem also a bit worn as there is a slight wobble on the gear cluster

Probably the Freewheel Body. Might be the bearings or the pals need a good cleaning so they can engage properly.

 

The Freewheel Body attaches to the Hub. The Cluster(group of sprockets) sits on the Freewheel Body.

 

You can replace or service the Freewheel Body without replacing the Hub.

Maybe just a service. Maybe a new freehub body (not whole hub)

 

Wobbly gear cluster sounds like whoever put your cassette on forgot to put the spacer in, or didn't tighten the lock ring. Can you wobble it with your fingers?

When the FWB's bearings are shot, the Cluster normally starts to wobble when the wheel is spinning, this can eventually effect the gears.

Make and model of hub would be useful. Different brands have different ways of giving uphill and different ways of sorting them out.

The Rear Hub is Shimano FH-M475 VIAM.

 

The Freehub Body I noticed wobbles when the wheel is spinning. i.e the gear cluster wobbles slightly.

 

I did not know this unit can be pulled apart.

 

I assume you need to buy a tool that would cost more than the part?

 

Thanks for the advise chaps. Will see what a new unit costs.

Cassette tool, chain whip, 15 and 17 cone spanners, a 10mm allen key, some grease and a replacement freehub body and you're good to go. Shouldn't take more than half an hour.

I would suggest testing it before greyton on the weekend - go for a short decent ride (at least 10km) after repairing - you don't want a nasty surprise when you go out for a long ride on the weekend. you can also take it a shop and ask them to assist you, so that you at least know how to do it correctly..

No time to test - straight replacement, was easy job.

Part was exact copy so all good

I was hoping the new FWB would improve my time, but alas, all I got was a smooth race with no more ringing the plums on the crossbar.
