Re: Towing related? what is the cause for the vibration?
Dragging car as you describe could cause damage to numerous parts of suspension i.e top susp strut mounting , driveshaft . brake flexible hose , track control arm anchorage etc . etc . Sounds like driveshaft c/v has also jumped out and may have been rebuilt / re-assembled with missing needle bearings on joint . Be advised to have a good check on driveshaft .
