my car now have a seem like a whine noise only at speed 50kmh, not a grinding or squeaking noise..noise like a belt whine (woo sound) but only when the car move, no whine in idle, only sound at speed 50kmh, after that speed no whine sound
check auto tranny fluid level - optimum, not dirty or smell burn (still red color)
check EO level - optimum
checking v belt - not loose and not so tight (no whiny sound when idle)
checking coolant - optimum (no leak)
no trasmission jerking, stiff or stuck, acceleration smooth
turn ac on /off also got sound
sound only at speed of 50kmh, below and above the speed no whine sound
recent services: EO and oil filter change, air filter and spark plug (from toyota SC) last month
mileage: 120,000km

nope, but the sound only when i press the gas, if i let off the gas pedal no sound.. so i don't think its a wheel bearing
I guess is tyre...
