If your vehicle creaks and squeaks when you drive down the road, it may mean that some of the metal parts are rubbing against each other and need to be lubricated.  Those could be parts of the suspension, steering system and the drivetrain. 

Years ago, most vehicles had to have their chassis (what you think of as the frame) regularly lubricated.  Newer vehicles are made with what some call "lifetime lubrication," but there are still parts of the chassis that need to be maintained with lubricants.  Your service advisor can help you know when that needs to be done.

In your owner's manual, the vehicle's manufacturer lists components that need regular maintenance. Things like u-joints, steering joints, sway bars, bushings and joints in the suspension. Some of them may have that "lifetime lubrication," while others may not. When you bring your vehicle in for service, a technician will look for any parts that have grease fittings.  They will inspect these components, clean the fittings so dirt and other contaminants won't be forced into the part and then lubricate them with a lubricant that meets the manufacturer's specifications. 

Sometimes a chassis lubrication is done at the same time as an oil change.  That's also an ideal time for the technician to check other parts of your vehicle that may need attention.  That could include greasing other parts such as the fuel door, trunk and door hinges, suspension springs and door latches.

Times have changed since the days when a "lube" job was synonymous with an oil change. Depend on your owner's manual and advice from your service advisor to know when "grease" is the word—and appropriate for your vehicle.
