Inspect For Grease Leaks And Damage

WARNING: This page is about a different car, the 2015 Mitsubishi Lancer. However, it is still accessible from the selected car via links, so may be relevant.

These components, which are permanently lubricated at the factory, do not require periodic lubrication. Damaged seals and boots should be replaced to prevent leakage or grease contamination.
Inspect the dust cover and boots for proper sealing, leakage and damage, and replace them if defective.
