@Xulfiqar and other experts, question in issue concerns gov owned corolla 148000km driven
it was sent to a toyota dealership(i wasnt present) 7000km ago for wheel balancing, alignment and brake service, ever since it returned there is a extremely loud roaring sound from all 4 tires at above 30km/h speeds and it increases the faster the car goes, its not the engine as sound is present even in neutral.
i thought maybe they didn't rotate the tires right or something and didn't bother about it. the sound hasn't increase dover 7000km but stayed constant.
somebody who had a ride in the car today said that wheel bearings should be checked and its dangerous, the car has michillen tyres and i today checked back to back with another corolla which had eurostar tyres and even the euro stars were quieter.
can it be wheel bearing issue? if so why did it suddenly appeared after alignment, brake service and although very loud roar, it hasn't increased in 7000km, the tires are 2014 manufactured and no cracks or rot and are fairly less driven, i have checked for binding brakes but they are fine as the rim and adjacent area dont get hot even after a long drive.
