Driving home tonight I noticed a horrible knocking/rumble from my driver's side wheel. I noticed under the car that something is loose and moving around on my drive shaft. I'm hoping-throgh a bit of google-ing that this is the drive shaft vibration damper? Can anyone help. It's the large red doughnut in the picture that's released itself from its sleeve and end cap. https://ibb.co/rf7DJWs
If it wont just slide back up to the inner piece you can just chop it off, some models didn't even run them
