Humming in the back
2000 GrandPrixGTP 145000 miles.Well replaced the front left wheel bearing, lower control arm bushing and tie rod end. The shudder is gone now. But still have the humming. Got my wife to drive the car and I got in the back and opened the seat fold down part and put my head in the trunk. Pretty sure it is the left rear wheel bearing. Got the bearing but need to know what the torque spects are for the mounting bolts? Plus spark plug change how hard is it to change the back ones? This is fun. Sure improved the driving.Thanks

Re: Humming in the back
Changing the back side plugs is no fun or piece of cake. A flex socket will help as well as being a contortionist. I had my dog-bone mounts off due to doing other work and that allowed the motor to rock forward a tiny bit and that helped. Be patient and take your time cause it's a real be-ach.
