Check that the roller bearing has been installed in the drive shaft just behind the speedometer gear. If this bearing is missing, the drive shaft will be whipping around inside the torque tube creating the up/down motion you describe. If missing, you will have to remove the rear spring shackles and disconnect the universal joint to install the roller bearing and thrust washer. Ed

What's involved to check for this bearing? What do you need to do or dismantle to see if it's missing? Wouldn't you hear some noise from the shaft flopping around inside the torque tube? Thanks.
