I have been chasing a vibration in the front end of our 97. It is when you put the brakes on so I figure warped rotors. I have changed them, brand new, and the vibration continues. I have had the struts changed, all in ones, and last week even had the front tires checked for balance. When I changed the brakes I checked for play in the hubs and did not seem to find anything. I once had a Subaru that the rear brakes were shot and it vibrated when I braked. I guess because of the fronts were working so hard. That is my next try. Any suggestions would be appreciated. Thanks. Jim
