Do newer cars have grease fittings?

In recent years, the design and construction of automobiles have evolved significantly, leading to changes in various components and features. One such change is the presence or absence of grease fittings in newer car models. Grease fittings, also known as zerk fittings, are small, threaded fittings that allow for the application of lubricating grease to various moving parts of a vehicle.

Grease Fittings in Older vs. Newer Cars

Traditionally, older car models were equipped with numerous grease fittings throughout the vehicle, allowing mechanics and owners to regularly maintain and lubricate critical components, such as suspension joints, steering linkages, and wheel bearings. This was a common practice to ensure the smooth operation and longevity of these parts.

However, in more recent years, the automotive industry has moved towards a different approach. Newer car models often feature fewer or even no grease fittings, as manufacturers have opted for alternative lubrication methods and designs that require less maintenance. This shift is driven by several factors, including:

• Improved materials and manufacturing processes that reduce the need for frequent lubrication


• Increased use of sealed, pre-lubricated components that do not require external greasing


• Efforts to simplify maintenance and reduce the overall cost of ownership for consumers

As a result, many modern vehicles are designed to be more self-sufficient, with fewer points that require manual greasing, making them more convenient for owners and reducing the need for regular maintenance visits.

Implications for Maintenance and Repair

The absence of grease fittings in newer cars can have both positive and negative implications for maintenance and repair. On the one hand, the reduced need for manual lubrication can save time and effort for owners, as they no longer need to regularly access and grease various components. This can also lead to cost savings, as the frequency of maintenance visits may decrease.

However, the lack of grease fittings can also make it more challenging to diagnose and address certain issues, as mechanics may have limited access to critical components that require lubrication. In such cases, the repair process may become more complex, potentially requiring the replacement of entire assemblies rather than just the application of grease.

It is important for car owners to familiarize themselves with the specific maintenance requirements of their vehicle, as the presence or absence of grease fittings can significantly impact the long-term care and upkeep of their car.

What car parts need to be greased?

Parts of a car that need to be greased include the chassis components like ball joints, tie rod ends, and bushings, as well as door hinges, latches, and wheel bearings. Additionally, certain drivetrain parts like U-joints and CV joints and brake caliper slide pins require lubrication.
 
Chassis and suspension

• Ball joints: Located where the suspension arms connect to the steering knuckle. 
• Tie rod ends: Part of the steering linkage connecting the steering rack to the wheels. 
• Bushings: Found in control arms and sway bars, which are rubber or polyurethane parts that cushion and allow for movement. 
• Sway bar links: Connect the sway bar to the suspension. 
• U-joints: Universal joints on the driveshaft or half-shaft that allow for changes in angle between rotating shafts. 
• CV joints: Constant velocity joints used in front-wheel or all-wheel drive vehicles. 

Brakes

• Brake caliper slide pins: These pins allow the brake caliper to slide, ensuring even pressure on the brake pads. 

Drivetrain

• Wheel bearings: Found inside the wheel hubs to allow the wheels to rotate smoothly. 
• Gears and splines: Found in components like the transmission and driveshaft. 

Body and other parts

• Door hinges: Lubricate to ensure smooth operation and prevent squeaking. 
• Hood and trunk latches: Keep them from sticking or rusting. 
• Weather stripping: Helps keep moisture and air out and can be lubricated with a product like silicone spray to prevent cracking. 

Do cars have grease points?

No, most modern cars do not have grease fittings on their suspension parts because many components are now sealed and "lubed for life". However, some older vehicles or certain aftermarket and heavy-duty parts may still have grease fittings (also called zerks) that require periodic lubrication. To be certain, always check your owner's manual or have a mechanic inspect your vehicle. 
Reasons for sealed components

• "Lubed for life": Many manufacturers now produce suspension joints, ball joints, and tie rod ends that are sealed from the factory and do not require service.
• Reduced maintenance: This design change aims to reduce the need for regular maintenance, as many car owners were skipping lubrication, leading to premature part failure. 

When you might find grease fittings

• Older vehicles: Cars made before the late 1990s are more likely to have grease fittings on suspension components. 
• Replacement parts: Aftermarket and replacement parts, especially those for performance or heavy-duty use, may come with grease fittings for longevity. 
• Specific components: Some parts, like certain U-joints on rear-wheel drive and all-wheel drive vehicles, are designed to be greaseable and will have fittings. 

What to do

• Check your owner's manual: This is the most reliable source for determining if your vehicle needs lubrication and which parts require it. 
• Listen for noises: Squeaking or creaking noises over bumps can be a sign that lubrication is needed. 
• Consult a mechanic: Your mechanic can inspect the chassis and determine if any parts need grease, especially during a routine oil change. 

Do modern cars need to be greased?

Everybody knows that automobiles require periodic oil and filter changes. However, many people do not realize that joints in the front ends of modern-day cars are permanently lubricated. This means they no longer need to be greased with periodic shop visits.

When did they stop putting grease fittings on cars?

In the 1980s, many auto makers eliminated greasing points because they believed that the quality of grease had so improved it would last the life of the car. But motorists knew better.
