Is my wheel bearing about to grenade at 3700 miles?!

[Stephen.G.Fiddes]

So the last few rides, Ive noticed some front end noise. Its a small squeak/ chirp. At first I thought it was the brakes, but as I was going downhill in my neighborhood, I shut the engine off so I could hear better, pulled the brakes, could hear the standard brake noise (scraping metal, as it should be, not squealing) but the chirping never went away, no matter the brake pressure. The chirping did change with the speed of the bike tho.

Id much rather have my front wheel not lock up on me as I'm going down the road, but wanted to check here to see if anyone else had experience before I call the dealer for warranty. Ive never had a wheel bearing on a bike go bad so I'm not 100% sure what the symptoms would be, but I'm pretty sure thats what it is.

 Put it on the centerstand and get the front end off the ground and feel it during rotation. Generally but not a hard and fast rule, if you can hear it making noise it surely is going to fail in the very near future, same goes for if you can feel any roughness in the rotation. If you have to, remove both calipers and you should be able to isolate it better and more accurately.

Occassionally parts are bad, so it is definitely possible to get a bad bearing and surely warranty would cover it.

Otherwise I would immediately get in touch with the dealer and have them pick it up if need be.

Having a bearing fail, especially a front is not a good thing to contend with. So if it is suspect I would not continue to ride it

I had a squeak going on as well after buying a used 2008.  The front axle and pinch bolts had been tightened by a gorilla.  After checking the bearings and seals, all I did was torque them as specified, and everything is totally silent with no binding and I have not had a problem since.   

[Stephen.G.Fiddes]

I guess I'll pop the front wheel off and actually feel the bearings... Was hoping to avoid that but now that other possible culprits have been mentioned, I'll have to check those first before I schedule time at the stealership.

if it has ABS, make sure to look at the sensor rotor, and the probe on the fork. If that is loose, it will rub the rotor....

[Stephen.G.Fiddes]

Finally got to looking at it, started by just spinning the wheel.... Noticed a lot of brake rub... is this normal? I don't remember my 650 rubbing this much... A little is understandable but this seems a bit excessive...

EDIT:  Upon further inspection (Without removing the wheel cause I need to buy a new tool to do that... Oh darn...) I didn't find anything to be super concerned about... I'm still a bit concerned about the squeak I've heard, but the wheel spun fine with the brake calipers removed, and slow turning and listening closely didn't sound abnormal... The ABS Sensor and all the associated peripherals looked good.

Some brake noise is normal.  The only way to really check it is to remove the pads, I would think.  Just put them back in the same place and position.  They're easy enough to remove by pulling the pins...but be careful, you only have about 5 seconds.

I pulled the entire caliper off (Good thing too cause the caliper bolts on the right side weren't as tight as they should have been) and inspected the pads.  Only one showed any damage around the edges (it was missing a small piece right at the wear mark line.  No associated damage to rotors) and all of them were clean.  Rotors were good.  I've pretty well ruled out anything brake related.  I'll give it a good listen tomorrow too when I ride, see if I can come up with anything... I'll also pick up a big hex tool if I can find one so I can pull the wheel off too.

I was dissapointed to see that kawasaki used the same brake pads on these, that they used on the 04-05 ZX-10, which are the most expensive brake pads to buy!!! (well, for a Japanese bike) (swapped a zx-10 front end onto my old 650)

So....how was the wheel spin with the calipers off? Still dragging? Any noise?

[Stephen.G.Fiddes]

Wheel spins great without the calipers. No dragging, no funny noises, spins freely.

I expect some brake noise (albeit, not quite as much as there is, but i dont think its a huge deal)  but I'm still confused as to what could be making the squeak/ chirp... Its definaltely not the brakes, and without taking the wheel off, it doesnt seem like its the bearings either.  Not completely ruled out, but doubtful.  Theres not much more moving parts up there...

[gPink]

My money's still on a brake squeak.

[Stephen.G.Fiddes]

Even though when I apply the brakes the squeak doesn't change? Only time it changes is with speed.

From fhe video, I think the brakes are dragging too much. Look in the calipers and make sure the leaf springs are installed correctly. You may need to remove pads and springs to inspect. Bleed the brakes. Hope it fixes it.

You can buy a tool specifically for removing the front wheel or you may have a spark plug socket that has the correct hex and use that.  Put it in the axle hole, then put your socket wrench extension in from the spark plug side and you can turn the axle nut.

If you didn't hear the squeek with the brakes off and spinning the wheel it probably isn't the bearings.  Did you try moving the wheel side to side to check for looseness in the bearings?  Grab the bottom of the wheel and push/pull it sideways.

It is a new bike.  Personally, I wouldn't go too crazy with removing and messing with things without first taking to the dealer, since it is under warranty.  Or at least don't tell them what you did (some might use it as an excuse to harass you).  Hopefully you have a good dealer.

But won't they charge me an idiot fee if it ends up being nothing?  (IE: Charge for the hour it takes them to take the wheel off and put it back on, or to tell me it is just the brakes...) If Odds are they won't charge an idiot fee, then I might just take it in...  If the dealer is good enough for Jay, good enough for me... haha

It could be just nothing, but it could also be something.  If it's something I can check for free, I'm apt to do that, because of how much I ride, and the fact that it's my only transportation. Basically all I care about is the wheel bearings at this point.  If it's not them, then there's nothing else up front that could make that noise that's going to kill me.

I've put over 1000 miles on it in the past 2 weeks, and have another 250 mile trip on Monday, and my schedule hasn't even filled up for next week yet, so I don't know whats in store for riding the rest of the week...  And to think I'm not even that busy yet...


And thanks to the gentleman for the tip on the spark plug socket... I'll give that a try when I find my brain...

I suppose anything is possible, but I don't think a reputable dealer would.

I guess I'll give them a call.

This is what my rear bearing on the GTR looked like after 25k miles. When I took the black seal off, the red cover was already loose
