Yes there's a bearing, but it's the axle tube that transmits torque from the diff over to the trailing arms and whatever else is attached to it. Bearings can't transmit or resist torque. Quote:
The pinion trying to climb the ring gear is exactly the opposite reaction of the torque to the rear axles. And the C-beam counteracts that. If you put enough power down, the C beam doesn't turn into a pretzel, but it does rip the front snout off the diff as the diff tries to twist upwards. Take that C-beam off (and put on a tranny mount) and dump the clutch, and the rear diff will tear loose from it's batwing bushings and rotate upwards into the floorboard. Yes the torque along the driveshaft is 1/3 less, but that is counteracted by the batwing and motor mounts, and transmitted to the frame. Now the dogbones, you could put the car on jackstands and remove them entirely, put the car in gear and punch it, and the knuckles wouldn't rotate at all. The only torque transmitted to them would be the bearing and brake drag, and the slight twisting of the lower camber rods with their glorious binding bushings. |
