Re: [Chrysler300] 300D Vibration

Look for a belt that is off-center, separated, or run-out too....

A number of Contemporary Historical Vehicle Association (CHVA) members have experienced belt separation problems. one of them cited a management person, "...Coker [is] aware of belt separation problems with radial tires...

  If the problem is new with the tires, I would look there. Typically tire 
  vibration due to balance problems are frequency (speed) driven but the 
  harmonic tends to be around 60-70 MPH on most passenger tires and 
  critical speed increases with tire diameter. 45-50 would be a bit low 
  but still worth checking balance - but FIRST I would jack it up and spin 
  fronts and look for out of round tire or wheel. Best is probably to put 
  a brick or some reference at edge of tread and see if distance changes 
  as tire rotates - probably should be less than 1/8 inch variation. If 
  fronts are good, you could swap rears to front to see if the problem 
  stays same of changes and of course look for out-of-round before you put 
  car back down. Then take it back to where tires were balanced and ask 
  them to recheck - its possible they made a mistake or you threw a weight 
  - but look for large amounts of weights as they tend to indicate tire / 
  wheel problems. Its also possible tires rotated on wheel - the old 15's 
  tend to fit looser than the 14's and I have seen it happen on race cars 
  - typically when too much tire lube was used AND too much HP applied 
  suddenly - but as I said the older wheels are looser fit and would be 
  more prone to such a problem. .
