| Noise | High pitched metallic noise | Poor lubrication | Improve lubrication |
| Clearance too small | Correct clearance |
| Poor fitting | Investigate mounting method and seating |
| Excessive load | Examine shaft and housing tolerances for closing effect |
| Low pitched metallic noise | Brinelled raceway surface | Avoid shock loads |
| Regular noise | Rust and damage | Check and replace seals and relubricate |
| Flaking of raceway surface | Improve lubrication and check fitting,clearance and fixing method |
| Irregular noise | Ingress of foreign matter | Check and replace seals and relubricate |
| Excessive clearance | Correct clearance |
| Damege and flaking of rolling element | Reduce loads and/or clearance |
| Variable noise | Variable clearance due to temperature changes | Check fits taking housing material and temperature into consideration |
| Damage to raceways | Improve lubrication and check fitting,clearance and fixing method |
| Heavy vibration | Flaking of raceway and rolling element | Improve lubrication and check fitting,clearance and fixing method |
| Ingress of foreign matter | Check and replace seals and relubricate |
| Excessive clearance | Correct clearance |
| Poor location | Ensure abutment face and fitting diameter are perpendicular |
| Excessive heat generation | Clearance too small | Correct clearance |
| Poor location | Ensure abutment face and fitting diameter are perpendicular |
| Excessive load | Examine shaft and housing tolerances for closing effect |
| Poor lubrication | Improve lubrication |
| Creep | Maintain recommended shaft and housing fits |
| Lubrication failure | Too much grease | Use correct lubricant quantity |
