The bellow protects the steering rack shaft and internal components from contaminants such as dirt, water, and road debris. It also helps retain lubrication within the steering system.
A properly functioning boot ensures smooth steering operation and prevents premature wear of internal steering components.
Function
• Protects steering rack shaft from dirt and moisture
• Retains grease and lubrication within the system
• Allows flexible movement during steering operation
• Prevents premature wear of steering components
Over time, steering rack bellows can crack, split, or deteriorate due to age and exposure to heat and road conditions. A damaged bellow allows contaminants into the steering system, which can lead to wear, stiffness, or failure of internal components. Replacing worn bellows helps maintain smooth steering operation and protects the steering rack from costly damage.
When to replace:
• Cracked, split, or perished rubber boot
• Grease leakage around steering rack
• Steering stiffness or unusual noise
• During steering rack service or rebuild
• Preventative maintenance on ageing vehicles
