How long should wheel bearings last?

[rumpelstiltskin]

Put front sealed wheel bearings on my TL1000r in July last year,2,500 miles later they're knackered!Noises were coming from the front but i didn't even bother to check them until now as a last resort as i knew they were done recently?

Does sir monowheel or use a jetwash?

Mine have lasted over 34k so far and are fine.

One rarely monowheels 'intentionally' and i only hand wash the bike,can't believe these have gone already!

hmmmm they shouldnt have gone that quickly!!!

ive never had to replace ANY bearings on any of my bikes most of which ive owned for at least 3 years, also ive had the blade since 2001 and still on ALL the original bearings

Sounds like they were either toast before you put them in, they were damaged when they were installed or the dust seals failed.

sounds like a problem, they werent loose fitting in the wheel or anything?
ive only done one set of wheel bearings on a 1994 bike with about 35k (at the time) last year & i suspected they where original.

The bearings were obviously new when i put them in,had to drift them into place gently after cooling them to make it easier.New dust seals were put in too.Must just be a faulty bearing?Other bearing on the other side is fine!

replace both as the addnl load from the knackered one will knock out the good one .

Sounds like it, I've never replaced a wheel bearing in 30 years of biking, even on old bikes.

I always replace both anyway,got them ordered!

Make sure the spindle is done up to the correct torque, as overtightening it can stress the bearings too. If they are sealed bearings with a fixed dust seal, you can gently remove the seal and add some extra grease, then refit the dust seal. I've fitted a few like this and its genuinely shocking how little grease they are packed with from new.

I suspect there was a problem or oversight with the last fit .

The wheels and assembly are the same as the Busa , I cant remember what it is right now , but there is a specific method for replacing the bearings.

Do a search for the info
