How Often to Replace Shock Dust Covers: Risks of Cracked Boots
Why Dust Covers Matter
The dust cover protects the piston rod and oil seal from dirt and moisture - the first line of defense for strut life.
Replacement Interval
- Recommended: Check every 40-60k km or 3 years
- Harsh use: Gravel roads, shorten to 20-30k km
- With struts: Replace together with shock absorbers
Risks of Cracks
- Dirt reaches oil seal, rod wear, oil leaks
- Moisture causes rust and noise
- Lost cover means fast strut failure
Inspection
Lift the car, squeeze the boot to check for cracks or stiffness. Replace immediately if cracked - cheap insurance.
