Last week I had to make a 30 mile run in a hurry to get to the airport. I love this car. One issue came up while driving . I went into a right corner very fast and I heard a grinding noise. sounded like it was the left wheel but not sure .I did it again to confirm and it happened again still I am not sure . This is what I do know that is wrong with the car at this time. One of the coils needs replacement so I ordered a complete MSD set of coils. the right CV boot is torn so I ordered both sides plus the bearings...the car has 124K but kept in really good shape. Could the steering rack be the cause of this noise....Thanks you for the time you took to respond....

 

Left wheel bearing needs to be replaced. When cornering the load shifts to the side opposite of the turn, ie. left turn load on right wheel, right turn load on left wheel. So with a grinding on the left side during a hard right turn, that indicates to me that the left wheel bearing is going out.

 

After investigating the noise we found the left front CV and bearing where bad. I replace both sides and car rides like new...Thanks.
