Noise #3- Driving home today I hit 75-80 on the freeway and I heard a sudden "HOOOOONNNNKKKKK.......HOOOOOOONNNNK" noise sporatically making a verbal appearance...never heard it before today.
I noticed something similar on my new 06 WRX Wagon. I believe the noise is from the tires resonating from the road. I've noticed that when i drive on certain patched or winterized road surfaces that the tire noise get's pretty loud. I also notice this on my lifted jeep with 36in tires. Hope this helps.
