bontrager rapid drive hub services

[phenning]

i had to replace the 2 main bearings on the hub . it has xd driver 

assembled it feels fine, but when tightened in bike the weel turns heavily 

i have assembled it without the free body and tightened it .then it spins fine.

 

my assumption is the free hub body an main bode pressress together and creatrs friction .

 

is there a missing spacer or something else im missing

You most likely lost the spacer that sits between the inner bearing of the hub and inner bearing of the freehub body.

A rather specific size as it needs to fit over the axle and its diameter is that of the inner race of the bearing.

there is no washer that sits between the two

Phenning check that the axle on its own cant move side to side , the drive side bearing goes deeper than what you would think.

 

then the freehub must sit flush on a flat surface i.e. the most inboard bearing needs to be perfectly flush ( this shouldn't be an issue as you said you just replace the hub shell ones )

Then the drive side bearing is not seated deep enough.

Just stripped my sons wheel down.

We did the 54 to 108 upgrade a while back.

Bagear is 100 percent correct, no spacer between the bearings.

Your bearings are most likely not seated properly.

At least you'll be able to keep up then...

On a serious note though, check that the freehub seal is seated properly and that there's no damage to either the bearing journals on the axle or any of the spacers between the bearings.

@droo thanks, nothing i can see. i may need ti take it to a pro

Make sure the freehub seal isn't the wrong way round. Some of them are directional.

Still not happy, just not tightening the axle very hard
