Help weird pulsating noise from rear
Hey guys, I've got a problem, and I'm coming up blank on an answer. Ok so I've been hearing a pulsating noise coming from the back of the car when I am driving. I thought at first it was u-joints, but I checked them out and they are tight and seem perfectly fine. I then thought that maybe both wheel bearings were bad because I can not tell what side the noise is coming from. So today when I lifted up the car I spun the wheel when it was still on the car and heard a grinding noise. I took off the wheel and spun the rotor, and again same grinding noise. I took off the caliper and pads and the noise stopped. So I know its not the bearings. I checked the pads and they look fine, they are both worn even and no cracks or anything wrong, and they still have plenty of meat left. So I tried to push the piston back in the caliper and it slid right back. I reinstalled the caliper and pumped the brakes to get the pressure back, and then I went and spun the rotor again, and the noise returned. The only thing I did notice was that on the rotor on both sides, the inside is worn down faster then the outside. Can someone help cause I am stumped and Im taking an 8 hour trip in a couple weeks are really dont want any problems.
Thanks guys!
Thanks guys!
