developed a loud clicking noise from rear wheel area,can hear it when pulling away and when pushing it in gear with clutch out till it rebounds

like something is under tension,also hear it click/knock sound when tightening the rear axle nut up

any idea's? think its a wheel bearing? they are fairly recent aswell,can feel any notchyness in them or any play :(
 
Post a video of it if at all poss. to help get a better idea?

The only things that spring to mind are cush drive play, worn chain/sprockets or over tight chain tension. Rear pads moving in caliper or caliper support bracket moving/worn?

If you've changed the wheel bearings recently I can't imagine it's them, but you do get part failure so best not to discount anything until you found the problem.
 
its like a creaking sound,chain and sprockets are new,i did oil the chain and it made it less loud but its still there
 
When you did the wheel bearings did you do the sprocket carrier bearings too? It may be that the strength of the new bearing have accelerated wear on the sprocket carrier bearings.
 
yh I did all three,could be one failing though or I culd have damaged one installing it but its really annoying

if I hold the front brake on and let the clutch out a little it will creak as the rear suspension/back end rises,but its from the back wheel/hub area,if I bounce the rear suspension theres no noise

also does the clicking if I push the bike backwards
 
Did you put the spacers back in correctly? It's surprisingly common for the cush drive spacer to fall out and for people to not notice during reassembly, which screws the bearing very quickly.
 
Yh,it knocks as I do up the axle nut,like something's under tension,I might just put new bearings in and take it from there
 
Get the rear on a paddock stand and spin the wheel, check chain tension, bearing play and brake pads.

Should be fairly easy to find where the noise is coming from.

If you cant see anything obvious then pull the wheel out and double check everything is there, is located correctly, and isn't damaged or worn.
Then reassemble making sure everything is clean.
Spin the wheel with the axle loose first then tighten gradually to see if/when the noise returns.
 
Creaking sound is what I had on my car...couldn't work out what it was...then the wheel bearing collapsed.

Does the creaking tempo change according to speed or stay constant?
 
that's when you first hear the click sound as you tighten the axle nut,it clunks as you turn the nut,

ill have to get it up on the stand,its a pain balancing the spacers/wheel/axle bolt aswell when your on your own

I dont think its the chain ive drowned it in oil
 
New wheel bearings arrived today,it doesn't seem as loud now but you can still hear it,I'll stick new bearings in and hope that cures it
 
They are sealed,when I took my bike to have two punctures fixed I remember him fully immersing the wheel in a barrel of water,it could be that but if they already had grease in them I can't see how it would affect it

Gotta finish tiling my bathroom first n I'll put em in
 
While your bearings are out check the crush tube isn't damaged on the ends, also check the length.

They'll also be a set way to install the bearings, you'll put one in all the way and the other will go to within a set distance of the crush tube.
Check the manual.

Sorry if you already know that but its critical if you want the bearings to last.

If fact, check the crush tube clearance before you remove the old bearings.
 
you mean the spacer tube inbetween? yh it has a tiny ridge both ends so it wont go too far

I found what it was though

:eek: dryer than Ghandi's flipflop,they were only three months old aswell and was stiff to rotate,yet when it was in the wheel it would turn ok,allsballs bearings,but only one was dried out so I just changed that

out of curiosity I carefully prised out the seal and this is on a brand new bearing,hardly and grease at all

so packed both of them full of grease and popped the seals back in

bottom one is one ive greased up

so note to self,dont let handfisted mechanics emerse your wheel in tubs of water,and when you get new bearings pop off the seal and pack them with grease as the japs must be on a grease ration

tightened the wheel axle nut up and no more graunching,so looks promising,wont be able to tell till tomorrow when I pop out on it
