i got a 2000 jetta gls 2.0 4 cylinder. in the past few weeks, i have noticed a front end squeek when i go over bumps. when i have it in my garage, i can push down on the hood and get the suspension to make the noise. anyone had this problem or know how to fix it? ive tried spraying silicone all over the suspension and it did not work. any ideas are appreciated. thanks
