grinding type noise from front

[5_19]

I have about 35000 miles on my 2001, and I have been hearing a noise coming from the front when I go around a curve. How do I know it's just the tire and not the bearings. The faster I go the louder it gets. No noise when going straight . I have never replaced the wheel bearings.~TJ

  You won't like it, but you need new wheel bearings. If it was the tire you would not hear a grinding noise. When the beaings start to go, you only hear the noise when leaning the Valk.

If you are going slow (20-40 mph) and hear it, it could be the bearings. If you are going faster, 50-70 mph, it could be the wear on the front tire, or the bearings. . My front Avon with 14,000 miles roars when I turn left or right. Straight, and she is quite as can be.

It may not be from the front at all.  Sounds like your rear tire may be cupped.  Straight up will feel and sound fine, but countersteering will make noise and you can also feel it in the bars.  You will think the sound is from the front.  Comes from running too low pressure in the rear.  I would not run less than 45 in my rears.

I'll bet it's the left rear wheel bearing. The sound source can be deceiving. If it's truly the front, I'd look at brake pads and front bearings.

Grinding could be brakes dragging. Check the pad wear for any anomoly. Also check your fluids. Easy first step.
But it does sound like a bearing to me.

Bearings easy to check.  Pull the axle and stick your finger in the bearing and turn. If the bearing is bad you will feel it when you turn it.

by any chance,
because most of the metzeler fronts i had, started to make a rolling side when riding slightly on its flanks, (while in a turn, or while riding up a rut in the street) ;only after a couple .000kms, did'nt do it while running straight.

I was told once : "its normal, live with it"
or
"if that tire wouldn't have already 3.000 km on it, we would take it back and replace."

That sounds like a left (outer) rear wheel bearing starting to go to me. It will get progressively worse, especially in corners. Then it will get louder when applying rear brake also. Both cornering and rear breaking will add stress to the bearing, causing you to notice it more. If that turns out to be the culprit, make sure you check and grease your splines too.

Thanks for all the good replies. I have ordered new bearings, seals etc. going to replace to whole lot front and rear, not taking any chances on a 8 year old bike with original bearings. Let y"all know what I find~TJ

Replaced all the bearings and the noice is still there. I do have METZLER front tire, and upon close inspection (very close) it does show sighns of cupping. This will be the last Metzler for me. Thanks~TJ

Mine had a 'grinding' noise while 2 up turning right. Thought it was wheel bearings but ended up being the rear brake pads rubbing the rotor. Do what you want but I took my rear pads off and ran it. Noise was gone, so I new it was the pads. You could try it on the fronts and rears if you want. But not at the same time!  I'm on my second Metz front and never had any probs. Is it a constant grind or does it 'sound' round?
