Noise On Toyota Yaris

[hammerman]

Just started getting a fairly loud humming sound on my 2001 Yaris which has 140k on the clock.

it's between 60 and 70 mph but ive also started getting a vibration or kind or grinding which i feel through my pedals.

The noises/grinding happen whilst the car is in motion and only at certain speeds which tells me it's not engine related.

Any suggestions....i had the O/S front wheel bearing changed last year....could it be that again, there's no squeeking at all, just this humming a vibration/grinding.

Any help appreciated

When changing the Bearing did they check the bearing housing for wear? it sounds very alike a bearing, If you can, jack up the car "WITH SAFETY IN MIND" with the N/S Wheel off the ground hold the Tyre / Wheel at 12 + 6 O -Clock, can you feel movement? that either shows T/R/End wear but can indicate bearing wear, also Spin the Wheel and listen for unusual grinding sounds, try that each side of the car, on a point, if you are doing this at home make sure someone knows what you are doing in case something happens, also check the drive shaft U.Js N/S + OFF/ S.

Does the noise change when cornering?

My guess is a warped (or otherwise damaged) brake disc, with the brake pad binding on the disc - but that's probably because I've just forked out for new discs and pads after getting intermittent vibration and grinding noises, plus a bit of a 'hum', at various speeds ;-)
