i have a couple things that i don't understand on my 2010 ls460l awd hopefully you guys can steer me in a better direction

#1 is i have a humming noise that specifically comes on at 40mph, i notice it up until about 60 mph but i don't know if it drowns out because of tire noise or it disappears.

#2 i got all my rims fixed and even replaced my tires and i still have wobble that i start to feel between 50 and 60 mph, don't know what to do next

#3 my rotors always warp in literally no time, maybe under a thousand miles, and it always seems to be the right front, any ideas?

plz just give me whatever feedback you can I'm all out of ideas

 

We're going to need some more details like, how many miles on this machine, are the wheels OEM, same thing with brakes.

Preliminary assessment, however, breaks down like this:

1. Wheel bearing. See if, while it's humming, turning right or left (like on a freeway cloverleaf exit, or even changing lanes, in some cases), going either way changes the volume. Make note of which directions do what.

2. When you say "fixed", what-all was fixed? Curb rash or rim dents? Did you have it aligned, afterward?

3. If the brakes are stock, yep, that's what they do. We've had people here with brakes warped brand new, just off the lot. IIRC, the car had less than 50 miles on it.

 

It sounds that one of the front tires or both front tires is/are out of balance. The typical sign of unbalanced tires is that the wheels feel warped (shaking/vibrating) at certain speed range (in your case, between 40mph-60mph).

 

Did you solve the problem? If so, would you please share with us what was the problem and how you solved it?
Thank you.
