My 1997 850 T-5 wagon has been dealership maintained since it was purchased. Shortly before it had 60,000 miles it would occasionally make a growling noise when the brake was applied. You could feel it vibrate in the brake pedal as well. It was rather frightening to say the least! I took it into the dealer and requested the 60,000 mile service plus asked them to check out the brakes. Dealer comments on the service receipt read: Check grinding noise from brakes; we checked all brakes; pads look good about 80%; front rotors have a large lip but we did not duplicate any noise. A few days later, the wagon made the same noise again. Since it only did it every now and then and the dealer had said my brakes were ok, I ignored it. I figured the dealer would have to keep my wagon indefinitely and drive it everyday for no telling how long to 'duplicate' the noise. Now, at approximately 70,000 miles, I have noticed what I refer to as a wah-wah noise when I driving. Its a rythmic noise that sounds like it's coming my front left wheel in particular. It excels and slows with speed. It seems more noticeable when I am making a right turn. I have had my tires checked to make sure there was nothing wrong with them, like balancing, worn, etc. After reading some of the items posted on your site, I am now concerned my front rotors and possibly wheel bearings and complete hub assembly may need replacing. How costly is this on average through a dealer? Do you have any other suggestions? Help!
