Squeaking Novatec hub

matt@theforce

Over the past couple of weeks I've noticed a squeak appear from my front wheel when riding, I only does it when riding not when the wheel is spun in the workstand.

The front hub is a Novatec D351SB & covered over 2000miles, alot of xc wet/gritty miles. I've done a quick google trying to find somewhere who sells the bearings but not found anywhere.

Does anyone have any pointers on where I can get some? I will probably also replace my rear wheel bearings at the same time (D812SB), while they are fine at the minute a bit of preventative maintenance never hurts.

Thanks
Matthew

Novatec use standard bearings, so you can just order from someone like SimplyBearings. The part numbers should be written on the existing bearings. For example I have a 609 2RS on my desk, which probably came out of a Novatec hub. 609 defines the size and 2RS means 2 rubber seals (which is what you'll want).

You can also get more life out of sketchy bearings by prising off the seal with a scalpel, flushing through with something like GT-85 and then regreasing (and replacing the seal). Not as good as replacing them, but can be quite handy when you need them sorted in a hurry and don't have any spares available.

Edit: You'll find there's a range of qualities available. Bearings from someone like SKF probably have better seals (and may be manufactured to higher tolerances); my suspicion is that Novatec use the cheap ones...
