| I guess in more than a year from the original post the problem was solved, but I will still answer just for the record.
Having the same car/model and model year, I experienced the exact same problem two years ago and after a trip to the dealership and $50 later the problem was solved. I suspected ball bearings (which would have been covered by warranty), but they claimed it was rust built up on the rear drum and just a simple scaling was all they had to do.
In the last month I have experienced those simptoms again and this time I decided to check the drum myself and try to scale it. Sure thing it was well rusted and after removing the rust that came in contact with the non-moving parts, the noise dissapeared. It looks like this is a problem affecting some 2002 Corollas.
Hope this helped. |
