I am not a profesional. This is just my opinion. I could be wrong.
Are you sure it's a wheel beering? There are other things that can go bad and make noise only during a turn. My experiance a wheel bearing will make noise going straight and get louder as speed increases. More of a Howling noise. But hey my howling can be your humming and it could also be that the bearing isn't that bad yet. Basically what I am asking is have you done the correct Diagnosis and canceled out all possibilty's? For example. If trans fluid is low it can also cause the trans to make a noise during a turn. I am not saying it isn't the bearing. But just double check to make sure.
I would check yor suspension. Could be a number of things. Steering, suspension, ball joints, tie rods, control arms. But it could also be something serious so it's better to have it looked at before it gets worse.
I have heard this many times on my 300m. I know the car is different..but with a rear wheel drive there's not much else it could be right? Steering is very tight and I cant check the tranny. Nearest dealer is 200 miles away. Gonna order the peake tool as I will need to change the oil. If I spin the wheel I maybe won't here anything as it is not that bad yet.
Feels like its coming from the floor on the passengers side. Lots of bearings on Ebay to. cheep ones and expensive ones. Watched videos on Youtube on replacing it..no biggie.
Blow you away story..I bought the car at the dealer auction up here..it was missing a center cap on the wheel. Went on Craigs list to find one. called a guy that had on 150 miles away. He asked where I got it..told him the auction but the car has StCloud Hundai advertising plates on it. It was from St Cloud I said. He asked is it silver? I said yes, He said "thats my car". What a freeky deal. He had an extra cap..and we talked about the car. Head gasket went out and they wanted 4k to fix it, so he traded it there. Now I learned they put a different motor in it. The people there aren't to cooperative to tell me much. Will call them again. Thanks guys for the help..this sight is really helping me know how to work on this thing. Getting prepared
No wobble in the wheel and spun it
cant here anything bad but the calipers are still on. Sounds more like a whine on a right hand turn like its low on fluid but its full. Looks like someone put synthetic fluid in it..its clear fluid. Joints all look tight. little oil on the Rack on the bottom..may be from the engine. all else is clean. Really tight steering like maybe toed in to much. having a chance to drive it again here as the roads are drying up. Should I put some bearings in?
well..I jacked mine up also, spun the wheel, no noise. Then I took the caliper off and spun the wheel, no noise. I have replace a lot of front bearings in other vehicles and was pretty sure of it being a bearing, you just dont know which one. A straight line noise could be a bearing also but vibration would mean its getting very bad and needs attention now. After I got the bearings off and spun them they were definitely bad. Calipers could be hanging up also and warped the rotor. If it hums or makes noise when you turn mostly, I would bet its a bearing. If you plan on DIY its pretty easy except the strut is in the way on mine and had to loosen it and move it up to get to the front bolts. Make sure you put them back in with the extention on the bearing hub facing rear. There are youtube video's also if you want to look it up.
