I am trying to pinpoint a problem with my g8 when I let on and off the gas usuaully above 30mph I will feel a clunk which feels like its in the rear end. I have the bmr street bushings. I also do expierince a loud pop when in 4th or 3rd and low a low speed and gas it. Im assuming the bmr bushings have worn? but if i take the ass off the ground and spin the wheels back and fourth i can feel some amount of play before the driveshaft spins and somewhat hear a clunking sound. So maybe its the diff? I have the geforce one peice driveshaft aswell. any tips and advice would be nice!
