Last week I had the brakes replaced in my 2001 Explorer Sport...new pads all around, new rotors in the front, and turned rotors in the back. The first time I got on the interstate (60+ mph), I noticed a vibration and a low-frequency noise coming from the front end. The vibration and the noise both increase significantly when I hit the brakes. Also, the vibration gets worse if I am turning slightly to the left (still at highway speed only), but not to the right. The vibration is not constant; it only happens for the first 20-30 minutes after I get up to highway speed, then it goes away and driving feels normal.
I've talked to a few people, and gotten a different possible explanation from each of them.
- separated belt in a tire
- bad bushing
- something wrong in the steering linkages...ball joints, tie rods, etc.
I guess it could be any of these things, but one thing doesn't make sense...why did this suddenly start after I got my brakes replaced?
Any thoughts on what could be wrong?
