5/13/1999:took car in for 10K check-up. Advised dealer that I was experiencing a frontend shudder at higher speeds or upon acceleration. Dealer rotated tires and found no shudder. 5/14/99:after getting on freeway, experienced a loud humming and thumping noise from fron-end and a vibration in the steering wheel. Braking increased vibration. My husband thought the lug nuts were loose on the tires and got off freeway and checked tires (no problem found). The vibration and noise did not abate even while slowing down to get off freeway.
