    Hi all,

    I had so much luck with my last question (about the rearview window
    rattle) that I'm going to go for broke and try to get an answer to
    another question :)

    In my '02 Elantra VE, when I step on the gas, I'm starting to hear a
    strange sound, like a belt grinding "whine" or "squeal". It is only
    apparent when I am accelerating, giving the car gas. In fact, the
    harder and more quickly I try to accelerate, the more pronounced the
    sound is.

    When the car reaches speed, the noise goes away.

    I'm sure it's something simple, but I know next to nothing about cars,
    except to bring them in for regular tune-ups and services :) FYI the
    car has about 150,000 km on it.

    Thanks for any help y'all can provide!

    It's difficult to give a good opinion without hearing the noise, but
    insufficient belt tension has a reasonable chance of being the cause. To
    prevent noise, the alternator belt usually needs to be tightened so that
    there's nearly no deflection on light to moderate pressure. The power
    steering and A/C belts should have a little deflection.

    This happened to me - but I can't remember what the solution was.... I'd
    check the alternator and/or if the battery is ready to die....

    Power steering pumps can "whine" and their noise would follow engine rpm.
    Does an Elantra have P.S. ?.....if so, you can check the pump's fluid level.

    My 2010 Elantra is making the same sound i believe the sound you're hearing is the differential. not power steering. because power steering will make a whine when stationary or get louder while steering. So basically the transmission needs to be replaced or rebuilt soon.
