I have been scratching my head on trying to figure this one out.   
      
   My wife's 2001 Durango has been having an intermittant odd feeling vibration   
   when hitting the brakes at 40mph.  It isn't warped rotors - it doesn't shake   
   the steering wheel.  It is more like driving over rumble strips type of   
   vibration and sound.   
      
   I had taken it to get new tires and they tryed to figure out the problem, but   
   it didn't happen enough for them to troubleshoot.   
      
   I'm thinking maybe swaybar bushings, engine mounts, or something to that   
   effect.  Visually, the only thing I see is a possible weak swap bar link (the   
   rubber part is not tight around the sway bar) on the passenger side.   
      
   Any idea/suggestions welcome.   
      
   Thanks.
