We just had our 95 Subaru Impreza repaired. The mechanic felt the front timing cover needed to be replaced and we agreed to have him replace the timing and AC belts while he was at it. When he went to remove the crank bolt/pulley he found it loose and the harmonic balancer had been wobbling and damaged the end of the crank. We have just under 88000 miles on the car. Is this normal for a Subaru that has been well cared for and not driven hard? During the winter when parked it is in a heated garage as this is Alaska. Just curious as we are considering replacing the car with another Subaru Impreza or Crosstrek.
