Possible bearing failure?, Now sorted :) - chunk166 - 15-08-14
Hi,Whilst on my way to work them morning i was getting a metallic sounding squeal/scrapping sound coming from the front end! I dont think its to do with braking as its there when i brake,its also intermittant!!!! I'm guessing a wheel bearing but i hope you guys can shed some light on it please!!!!!.
Thanks in advance

Not much up front to make that sort of noise really, either your pads are down to the metal, or as you say your bearings could be shot.

As Darrsi says, most likely pads. Bearings would have to be well broken up for them to squeal I would have thought. Put bike on centre stand and feel for play in the wheel and spin it to see if you can pin point the noise.

Sounds more like you've got a stone caught in one of the front calipers rather than a bearing problem. A bearing problem would cause the front end to go all wobblyexcept when you put the brakes on and the pads acting on the discs on straighten things out.

Stone in the caliper is most likely. It could also be the speedo drive dried out.

I will have a look at it over the weekend,pads are fine plenty left on them & the discs look ok!!!! The wheel is tight trying to rotate it the way it would when riding but looser turning it backwards??
Time to get dirty i think :book
mash :tape
Re: Possible bearing failure????? - darrsi - 15-08-14
Caliper pots ok, not sticking?
Take the pad pins out and give them a good clean up, and make sure there's no grooves in them so the pads can slide properly.
Re: Possible bearing failure????? - chunk166 - 15-08-14
All checked & cleaned up & re-greased last weekend!! Maybe i have disturbed something???
Re: Possible bearing failure????? - darrsi - 15-08-14
Could be that you put the pads back on differently, so they may need bedding in again for a little while?
Re: Possible bearing failure????? - chunk166 - 15-08-14
This it true but I don't understand why it started after 4-5 days!!! As a precaution i'm gonna order some bearings before i think about taking the wheel out because if i need to grease the speedo drive I don't want the bearings dropping out if there knackered!!!!

Collapsed bearings could cause an accident so you shouldn't ride it until it's fixed. As a quick check you could take the calipers off and try to spin the wheel and check if it spins freely. If it spins ok then it would point to the calipers if it doesn't then it's bearings but definitely take the wheel off and check the bearings properly.
Re: Possible bearing failure????? - chunk166 - 16-08-14
Unfortunately i don't have much choice but to ride it as public transport to where i work is almost non existent,but bearings ordered & should be here by tuesday! I will take off the calipers & spin the wheel to check if it spins freely or not. Any suggestions on how to keep the front wheel of the ground as i don't have a paddock stand or axle stands?? :rolleyes :rolleyes
Re: Possible bearing failure????? - His Dudeness - 16-08-14
If you put it on the centre stand and weigh the back down it'll hold the front wheel up. If you've got a top box on the back it's dead handy. Just load it up with heavy stuff. I use exercise weights. If you do find a damaged bearing you're taking a fair risk riding on it especially on the front.
Re: Possible bearing failure????? - darrsi - 16-08-14
Just give someone a plate of sandwiches and ask them nicely to sit on your pillion seat and eat them slowly. :lol
Re: Possible bearing failure????? - VNA - 16-08-14
Would have thought if the wheel turns OK and there is no play in the bearing (get somebody to hold the handlebar then try moving wheel from side to side - worn bearing will give a click click noise and you'll feel the play) then the bearing is fine.
Had a rear bearing let go on me, can be pretty scary. Limped the 12 miles back home at about 25mph. Sort of felt weird for a few corners, I was thinking - am I imagining that? - then it just let go.
If the front goes you'll be on yer arse before you know it - if you haven't smacked into something coming the other way. If I found play in my front bearing I would not ride the bike till fixed.
Re: Possible bearing failure????? - chunk166 - 17-08-14
Well! There is a bit of play in the wheel,but only noticeable when the calipers are off. I have ordered a set of bearing which hopefully i will get by tuesday & i can fit them in the evening!. I can't have time off work as their short staffed & the public transport is crap so i will have to use my bike but i will be a lot more careful than i normally am. Just need to make a frame up to sit the wheel in when i remove them

To be honest mate, if your bearings are that bad, I'd not ride it at all. There's nothing you can do about it, you might be able to ride okay until they're replaced, you may hit a pot hole and get have them disintegrate, or they may just randomly collapse on you. Without seeing them it's hard to say, but personally I'd be asking mates for lifts or using the public transport, even if it is shit. You have an accident with those bearings, and you'll be screwed, big time.

Well she is all locked up & going nowhere until its done :thumbup :thumbup :thumbup
Re: Possible bearing failure????? - His Dudeness - 19-08-14
Were you riding it when it locked? Hope not!
Re: Possible bearing failure????? - chunk166 - 19-08-14
Thankfully they didn't lock up,but it took me 35 mins to do a 15 min journey last nite coming home from work! So glad these bike have hazard lights.
