💡 Why does a steering shaft lower bearing fail prematurely in heavy tow setups?
Mechanics confirm that repeated angular shifts fracture the precision ball tracks over time.
- Frequent road impact forces increase metal-to-metal rubbing inside the protective cage
- Unsealed designs trap abrasive grit that accelerates inner race scoring rapidly
- Neglected lubrication cycles allow oxidation to eat away original zinc coatings
- A handy upgrade procedure returns precise rack geometry to factory alignment specs
