Solve my squeak?

Harrybelafonte

So I put new bearings in my four spoke wheel and it's spinning much better. However, when I tried to use it over the weekend it started to make a grinding/screeching noise which got louder and louder, then when I stopped, it'd barely turn at all. Anyone have any ideas? Something too tight? Axle need greasing?

- ball bearings (cup&cone) or industrial ones?
- if cup&cone, have you greased them well?
- have you tightened the cones sensibly - so that there was no rough feeleing when turned the axle by hand?
- have you secured the cones firmly by tightening the next nut against them?

Industrial bearings. All seems fine til they get a spin for awhile. No roughness when turning.

They. Are deffo they right size that were replaced?

I am not a mechanic, much less a bicycle mechanic, so take this with a grain of salt - but it sounds like the bearings may be too large?

Then the reason it would slow down/squeek when you spin for a while would be that they expand with the heat generated from turning, so that they go from being able to just about fit to being slightly too big, you might want to try slightly smaller ones.

Is there any difference in turning resistance when you mount the wheel and tighten the QR?

Perhaps they're not ideally parallel?

Are they symmetrical design - if not, are they installed the right way?
(are there asymmetrical bearings in bicycle industry at all?)

Thanks again guys. Definitely correct size. 6603s which I picked up from dixons. They were also replaced in the fear wheel which has given no problems.

I'd say they're not completely pressed in and run at some minimal angle... After all this grinding they may be gone by now, though.

Thanks for all the help guys, I'm just going to bring it into a shop and have it checked.

Sounds like the bearing is siezed on the axle.

Try a snicker wrench.
