First time poster. I have a 2001 LS that I bought with 70,000 miles. I have noticed a rattling noise coming from the front end between 30-45 mph. Took it to dealer, and they said the brake pads were missing the anti rattle clips, which was causing pads to move and make the rattling noise. Has anyone had or heard of this problem with their LS. Dealer said not to replace pads until they wear out.
