Toyota Repair Problems? Ask a Mechanic for Answers ASAP
Hello, my name is ***** ***** I am a professional here at Just Answer. I have noticed that your question was not getting a response and thought I would see if you still need help with this.I apologize for the delay and I hope I can still assist you with this here.One common cause for the type of noise you are hearing can be caused by a sticking ABS relay which can cause the ABS pump to run. The next time you hear this noise try removing the ABS relay.

Okay, have a look when you can . It is safe to drive with the relay removed you will just not have ABS breaking. The regular break swill still function normally.
With out being there to hear it I can not say for sure. Let see if its the ABS pump running and if not we can try and pinpoint it from there.
Sounds good. Good luck.
Where you able to pinpoint the area the noise was coming from?
At this point you are going to need to wait till it come back and once it dose try and locate the area its coming from and let me know from there. Im not sure what else you can do till then.
