The chassis supports the vehicle’s weight and houses the frame, suspension system, braking system, and wheels. Many of these parts constantly move when driving. To keep them from grinding against each other and causing damage, the chassis must be lubricated regularly.
Chassis lubrication involves applying grease or oil to the chassis and its connection points to reduce friction.
Regular chassis lubrication is crucial for older vehicles, but some modern models don’t need them as often because they have parts that are either sealed or “lubed for life.”
While a visual inspection will help you determine which parts need lubrication, the following components can always use the extra grease:
Neglecting to lubricate your vehicle’s chassis leads to a lot of problems – some of which can lead to permanent damage.
Driving will become more difficult and clunky due to worn-out or damaged parts, making it uncomfortable and less safe. Rough driving over long periods also leads to permanent damage to the affected parts.
That being said, most vehicles come without grease fittings because they have been greased from the factory. Replacement parts will, however, come with grease fittings.
Unless you have the right tools and know-how, it’s usually best to leave chassis lubrication to a professional who knows what they’re doing. However, if you’re curious about the steps mechanics take to lubricate chassis, here’s how the process usually goes.
Chassis lubrication is usually part of a complete oil change service, which is best done at least once a year. However, there are times when chassis components need lube immediately. Other times, no lubrication can be done because OEM ball joints and tie rod ends frequently come without grease fittings.
Poor steering and rough handling are some of the symptoms of a chassis that need lubrication.
A common sign of a chassis in desperate need of lubrication is if the vehicle becomes difficult to drive. This “clunkiness” could stem from increased friction in the ball joints, which will make it more difficult to steer and control your vehicle. It may not naturally return to center after a turn.
Poor handling usually goes hand in hand with steering problems. If you feel as if your vehicle veers towards one side when driving, have the alignment checked and the front end parts checked.
If your chassis makes noises, it’s usually too late for lubrication. When the boots are gone, the OEM parts that came without grease fittings will need to be replaced if they start squeaking (they need to be replaced anyway if the boots are gone).
Look for the place that’s squeaking first. Sometimes it’ll be a rubber bushing that is worn out and doesn’t require lubrication, just replacement. Control arm bushings are one example of such squeaking that has nothing to do with lubrication. Sometimes just tightening suspension parts where there are bushings will stop the squeaking.
