Ford Mustang (1999-2004) Service Manual: Bearings - Inspection

NOTE: If any of the following conditions exist, install a new bearing.

1. Inspect the bearing for a bent cage.

2. Inspect bearings for galling (metal smears on roller ends).

• Galling is caused by overheating, poor lubrication or an overload situation.
• If galling is found, install a new bearing and inspect the seals.

3. Inspect the bearing for brinelling (surface indentations in the raceway).

4. Inspect bearing for cracked inner race.

5. Inspect the bearing and raceway for etching.

• If etching is present, inspect the seals.

6. Inspect the bearing for heat discoloration (dark blue).

• If heat discoloration is evident, check the bearing and race for loss of temper. Draw a file across the component. If the file cuts the metal, there is a loss of temper.

7. Inspect the bearing for fatigue spalling (metal flaking).
