Hey all i have been researching quite a bit on what this possible noise can be. I have a 97 Grand Cherokee 2wd only. When i get to over 10 mph it makes a swooshing noise. Like the one from the night rider car. It's constant with both acceleration and deceleration. Checked videos thinking it was the pinion bearing and it doesn't sound anything like that. i did the rear brakes a while back but i'm pretty sure the noise was constant before that. Any help would be appreciated in figuring out what i'm getting into.
