I have a 97 cherokee and I hear grone from the front driverside wheel area
(sounds like road noise when someone has oversized tires on their truck) when the jeep is in motion . The faster I drive the louder it gets.
I think its a wheel bearing but when I took it to a mechanic to replace it he tells me the wheel bearing is fine , he then tells me the rotor and brake pads are whats making the noise.
Im no mechanic but the rotor explanation doesnt sound right to me
Their is no steering wheel shake when braking so I dont think its the rotor
Dude, he just told you what you thought was a $500 job is actually a $100-$150 job. Mechanics don't often save you money. I'd tend to believe him.
If you're wheel bearing were going (and I had one fail once) when you turn in a certain direction it will get louder. So, if you turn hard left or hard right it should get louder in one direction, but then seem to go away in the other, because you are either putting more stress on the failed bearing or taking stress off of it, depending on which way you turn.
If your pads have failed to the point that they are now laying against the rotor and ground goves into it... they could cause a lot of grinding to. (I've had this happen before as well) Once the pads ware through to the point that the rivets poke through, they start to grind groves into the rotor. Then the rives fail, the pad false lose against the rotor, and now you have a pad with metal spikes sticking out of it, laying against your rotor... even when you're not applying the brakes it's pretty loud.
put one hand at 12 oclock, one hand at 6, and rock the wheel with it jacked up. if there is any play, you have a worn bearing. dont place you hands at 9 and 3 because that type of play is a steering issue
