View Full Version : Nacked front wheel bearings
06-11-2003, 08:05 AM
Hello all, just lately i'm starting to hear a quiet yet nasty sounding scraping (noise level depending on speed, not power) and i'm assuming this is whats causing it (or at least the casing has split/come loose).
Are these a bugger to replace? <img src=http://www.ezboard.com/intl/aenglish/images/emoticons/ohwell.gif ALT=":\">
And should I not ride? :(

had mine go earlier this year luckily id just pulled out of work and got a few hundread yards up the road so wasnt going to fast mine had been making strange noises for a few weeks on and off didnt realise what it was, but if it goes when ur riding fast be prepared to come off as u have very little control over as it wobbles the disc moves so the pads wont stop you,
my reciept for the work is at work so i cant remeber the price think it was about £50 that was because the bearings were hard to get out apparently took 1 1/2 hours to do this was at a official aprilia dealer, i beleieve the bearings were fairly expsensive about £12 as you can get them alot cheaper but wether u can get them fit ones youve bought is a different story have you noticed any brown marks around the hub as if the grease is coming out?? also if the bearings go i was told they can damage the inside of the wheel as its only ali

is it my brakes or bairings, there is a scraping sound that i notice when i push my bike (engine off) it is a hiss, that sounds as if something is rubbing against something else. My instinct is that it sounds like something rubbing against by discs. Any tell tale signs.
Best diagnosis is take out your front brake pads then push your bike if the noise is still their then its your bearings i dont see how it took hour and a half it took me with the wheel off , 15mins its so easy (knocked by a dealer) the tricky bit is putting the new ones in make sure they go in straight i think i paid 20 quid for mine and they r better than aprilia , good luck anyway :D

no it didnt take the 1 1/2 hours to get the wheel off as i had already taken it off , it was getting the old ones out and putt ing new ones back in that took this long, it sumit that needed doing quickly and it was my only option at the time needed the bike back on the road to get to and from work.
Ohhhh sorry mate its bad when it comes to that its anoying how much we rely on the bike and have to resort to things

Thanks for that guys...now all i have to do is find an aprilia dealer round here and jobsagudden, which isn't easy as anything to do with bikes in yorkshire is few and far between.

From memory the size of the bearings is 6004. These cost me £6.50 each from a local bike shop (you can get them cheaper mail order). They are quite easy to change.
It is easy to check them. Get someone to hold the front of the bike in the air and then hold the wheel and try and wobble it. It you can feel some free play (ie a couple of mm easy movement) then the wheel bearings are shot.
All the best
