There are very few places where the chassis and steering can or should be greased. Most modern vehicle use factory-lubricated sealed joints. Normally only the lower ball joints and the outer tie rod ends can be lubricated and even then, often the factory components are sealed and only aftermarket replacement items will have grease fittings. Where possible, lubricate the chassis lubrication points every 7,500 miles (12,000 km) or 12 months with a quality chassis grease. Lubricate the transaxle shift linkage, park brake cable guides, under body contact points and linkage with white lithium grease.
