IS300 squealing
Hi all,
I'm new to this site, but not to working on cars, but this problem with my 01 IS300 has me stumped.
I was getting the constant squealing while driving thinking it was the wear tab on the front pads. I knew the pads were really low, so I got new pads and rotors. I had to replace just the pads and turn the stock rotors since my new rotors took forever to ship and it needed new pads bad.
Well, even with the new pads it still squealed. It started at about 20 MPH up to 40 MPH where the wind noise with the window down is louder than the squeal. It does it even without my foot on the brake, and the tone doesn't change when I do step on the brakes. So I figured maybe for some reason one of the shims was rubbing on the rotor.
When I got my new rotors I took it apart again and checked for anything rubbing but there was nothing. I thought maybe the pads were just vibrating in the shims on the bracket so I lubed the sliding points up too. I took it for a drive with the new rotors and no squeal. Hmmm. The next day I noticed the squeal again, but I noticed it only started after driving it for a bit, like whatever it is has to warm up.
It really sounds like a piece of thin tin riding across the rotor as it's turning, but there's nothing there touching it. Anyone ever hear of this problem or had a problem like it? I'm hoping it's not a wheel bearing but I've never had a wheel bearing make a noise like this. It's not super loud, but loud enough to hear while driving slow, especially when driving next to a break wall at 40. The "EEEEEEEEEEEEEEEEEEEEEEEEEEE" is really annoying.
Thanks,
Nate

Do you have a 5 spd manual by any chance?
I am asking because the symptoms you described point towards a faulty clutch release bearing.

No, it's an e-shift. It's not engine speed specific, it's wheel speed specific.
Usually release bearings start to rattle and chirp. This is a constant "EEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEE!" above 20 MPH, just like the wear tabs on the pads normally sound like.

Did you ever find an answer to this problem? I'm having the same issue.
UPDATE: Not long after this post, I went and got my brakes checked. They told me I was in bad need of replacing by rear brakes, which I thought odd since I didn't hear any noise whenever I applied my brakes. Still, I got it done and the issue was resolved...THE END.

yeah mine has the same squeel on the right side too! i replaced my left bearing and my brakes at the same time and although it fixed those it still has a squeel that i thought was apart of the bad bearing but the bad bearing was only on the left side not the right side.

I just recently bought my 2002 IS300 and this issue started happening when I replaced the tires. It is only when I make a right turn. I checked all the rotors, replaced all the pads and lubed them. This noise is driving me nuts. It sounds like its coming from the rear but at this point it could be at the front. the previous owner installed slotted and drilled rotors and poorly painted the calipers. I also had to change the tires because the previous owner had different tire size all around. he was mixing 235/45 with 215/40 randomly around the car. could that have messed up anything?

im having the same issue . Its pissing me off. when i drive it squeaks , i could be in park and itll squeak . i noticed when i hit the gas it squeaks on idle between 500rpms but this noise is decieving and it sounds like its coming from the back. Why would it start when i accelerate on park tho? any ideas? i figure this may be messing up my MPG. im getting horrible gas mileage.
