problem #4

G8

  • 79,264 miles

Left front wheel bearing ass'Y has been replaced twice because of moan/roaring noise that increases and decreases as speed increases and decreases. Noise becomes noticeably louder as you make a right hand turn - which causes the left front wheel to have an increase in weight bearing. Original replaced @ 78,042 miles. First replacement become so noisy that it was replaced @ 79,264 miles. Noise was lessened, but was still noticeable. Now, the second replacement is so noisy driving it straight down the highway that I am afraid to drive it @ 90,000 miles.
