I have developed over the last week a dull whining noise from the front end of my civic, and cant quite locate exactly what it can be.1 ) tyres are budget brand which are ready for replacement soon, no cupping just even wear, but rears are bridgstone and have full tread.2 ) inflated tyres to correct pressure and noise has reduced but is more noticable on rougher roads from 50mph+.3 ) jacked up front end & checked for wheel play & smooth rotation, all is fine but noticed the righthand drive shaft is corroded on the arm towards the cv joint, but no evidence of leakage.4 ) low speed left & right hand turns produce no sounds, no sounds on full lock either, round corners or round -abouts etc5 ) transmission is as smooth as always and brakes work more than adequatly.Any suggestions as this is an annoying whining noise which i aint experienced with worn tyres beforechecked out the wheel bearings last night and confident that they are fine, no play in either direction and rotation is smooth.still concerned about the righthand driveshaft being so corroded near the cv joint as the left hand driveshaft looks fine apart from road gunk on it.Will check the brake pads this week as the noise is fairly noticable at all speeds, and get a trusted mechanic to have a look too, before i start changing components i don't need renewing.
