wheel bearings?

[gdallas]

strange tone coming from my car, that kicks in roughly about 15-20 mph, and increases pitch as i accelerate. Old man is convinced its a wheel bearing! looking for some advice on whether this is an easy one to fix my self, or whethere i need a garage? im quite handy and like a challenge. is this the part i would need?

Have you tried the old jack up a corner at the time and wiggle the wheel test?

I have not... Could u elaborate please dude?

Also I put 4 new tyres on her about 2 months ago. I can't be sure but I think it's front driver side

Jack up each corner in turn. hold the wheel at ten to two or quarter to three and shake it rapidly a dodgy bearing MIGHT allow the wheel to move slightly and let you feel the worn one.

well the garage confirmed to me today, that it was the drivers side bearing for sure.
