Maintenance Tips
-
Check mounting torque regularly: Re-tighten all bolts after installation and re-check every few months, especially after off-road use.
-
Inspect crossbars & frame: Look for stress points, cracks, or bending after heavy loads or rough terrain driving.
-
Clean after exposure: Wash off dirt, salt, and mud to prevent corrosion and preserve coating finish.
-
Verify load limits: Always stay within manufacturer-rated dynamic and static load capacity to avoid structural damage.
-
Inspect hardware & brackets: Ensure all clamps, feet, and mounting brackets remain secure and properly aligned.
-
Lubricate moving parts (if applicable): Use light, non-greasy lubricant on adjustable components to prevent squeaking or seizing.
-
Check wind noise & vibration: If noise increases, re-check fitment and tighten loose contact points.
-
Roof contact protection: Inspect rubber pads or isolators for wear to prevent paint damage.
-
Routine safety checks: Before long trips, confirm all gear and accessories are securely fastened to the rack.
