When im driving at all times mostly when its in nuetral because i can hear it the best, my rear makes this clicking/ticking noise. I don't think its the bearings because i was told that would make a screeching noise or whistle. this noise is like something is stuck in the wheel and it rolls around but there nothing i took off the tire and checked. nothing. i jacked up the rear and spinned the tires to see if i heard it and i could'nt and then i went on to start it up and put it in first and try to hear it while the tires were spinning but still no noise. i'm out of ideas here guys. please help. at first i thought it was in the tires/wheels but it might be in the rear end. please any help would be greatly appreciated.
