Need some help pleasee!!! was driving home from work and at the first stoppage, I got this bad vibration. I could hear a little chatter almost little bit of a squeeking (like a pulley). As I continued to drive, I had no issues when when up to 60-80 but when i start breaking, you can feel a little bit of vibration then when stopped, the vibration goes into overdrive (and the car even shut off once). Can anyone give me an idea what imlooking at here before I take it in?
Thanks in advance

 

In addition to what i wrote...in idle it is fine..revs at 900 which seems normal...once i put it in drive or reverse..the severe vibration begins knocking the rpms to about 500 (and also shut it down)...please any input would help..

 

you may wanna check out the dampner...they are known to come apart!
