My car is making a deep growl noise
while driving straight down the road and when turning to the left. Turning to
the right alleviates the noise. Over time it has seamed to get
louder. We thought it was the wheel bearing or hub but even after we
replaced both, there was no change. Anyone know what's going on? Is it the

i have been fooled by this one way to many times. when a wheel bearing or hub assesembly is making noise, it will sound like it is comming from the other side. i do not know why this is. but one test will prove if and which one. when growling noise occurs, notice, when turning left or right, does noise get louder and quieter as you turn? if so then it is wheel bearing. when turning left the right side will make more noise. when turning right the left side will make more noise. if always the same then, tires or transmission need addressing. the cv axle does not make a growling noise, unless front wheel drive car does not move, it makes a clicking or poping noise. sorry but at least you dont have to replace other axle
If the noise sounds like a roar or growl increasing with speed, may come and go depending on turning left or right then you have a wheel bearing that has failed ( example; loud on right turn=left bearing as it is now loaded)
WHEEL BEARING USUALLY STARTS MAKING A ROARING TYPE NOISE WHICH USUALLY GETS LOUDER THE FASTER YOU DRIVE, SOMETIMES THEY WILL BE LOOSE , TO CHECK JACK UP THAT WHEEL AND GRAB TOP AND BOTTOM OF TIRE AND SHAKE, IF THERE IS MOVEMENT, TRY TO GET SOMEONE TO ROCK TIRE FOR YPU AND WATCH WHERE AXLE GOES INTO CENTER OF BEARING AND SEE IF AXLE IS MOVING WITH TIRE MOVEMENT AND SPINDLE REMAINS STATIONARY, THEN IT IS BAD BEARING, OR SOMETIMES THERE WILL BE NO MOVEMENT, THEN BLOCK REAR WHEELS AND RUN CAR WITH THAT WHEEL IN AIR AND SEE IF YOU HEAR NOISE, GOOD LUCK.
