Hello! I am hoping someone has some advance or direction to take. I have a gx 460 2011. In the past few months I have replaced the rotors, brake pads and tires. In the past few weeks there is a high pitched squeal that comes from the front. It happens when I turn right, go over a bump at low speeds and brake at low speeds. I do not have to be braking and turn at the same time as they happen on their own. I do not hear it when I am braking from a high speed or driving at a higher speed (that I can tell). I would appreciate any help or direction. Thank you for your time in advance.

 

i would suspect a wheel bearing going bad from the symptoms you prescribe. their life is usually around 100K but i have gotten alot longer. If you take your wheel off, and then rotate your hub, and you hear some binding, then that is probably the culprit.

 

When wheel bearings just start "to go" ... the noise is typically variable ... straight, turn left, turn right ... etc ... the noise briefly goes away between these changes in direction but then always returns. Lift the tire side in question and rock the wheel to test for bearing play ... any level of play indicates that the bearing is on the way out.

 

indicator rub, a rock, junk pads, good pads when cold.
The play test above is best for wheel bearing checks. can also go way fast down hill on a curvy road both ways and feel the difference.
Last time I had this I had a piece of gravel between the rotor and back plate.

 

Thank you! In your opinion, is this something easy to find or should I bring it to a shop to look at?

 

can see youtube videos, an improper wear indicator is uncommon, but removing a wheel and spinning the rotor is an easy way to find out. same for a rock. rocks will leave scratches too. can check wheel bearing at same time since you jack up that corner first.
should be able to do all those checks in 30 minutes by yourself no shop needed.

 

I have a similar problem on my gs. Not a break squeal (just fixed that on the right with grease on the shim), but a higher pitched groan when I'm 70 to 100% into a left wheel turn. Heard it might be a backing plate needing to pushed back? Hope this maybe gets you in the right direction if all those others dont prevail. Godspeed Lex Club.
