Confirm the noise by performing a test drive.
If no noise is heard, no further repair is
necessary.
2.
If the noise is confirmed, attach chassis ears
to the following locations:
- The knuckle where the source of the
noise is.
- The opposite side knuckle to compare
left and right wheel bearing condition.
- Other areas suspected of causing the
noise to compare the sound coming
from the knuckle to other sources.

or similar. Leave enough slack for
suspension and steering
