Alleviate the Creaks and Squeaks (Chassis Lubrication)

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.

Catalytic Converter Replacement

Many of us have become aware of how important it is to keep our planet’s air clean, and your vehicle has a key component that helps do just that: the catalytic converter.  It’s in the exhaust system, and its job is to superheat unburned, harmful byproducts in the exhaust, so they don’t get spewed out into the atmosphere.

There’s another important purpose the catalytic converter has: it improves your vehicle’s efficiency. 

Most of us don’t give the catalytic converter much thought until it breaks or someone steals yours, something that’s been happening much more frequently in recent years.  The reason people steal them is that catalytic converters use precious metals such as platinum, palladium, and rhodium to do their job. So, they contain valuable materials thieves can sell.

The most likely reason you will have to replace your catalytic converter is age.  The more distance your vehicle travels and the more hours your engine runs, it’s putting wear and tear on the converter.  T

You can tell if your catalytic converter is failing by looking out for these signs:

• Smell of rotten eggs inside your cabin or outside near the exhaust
• Check Engine light is on
• Vehicle power isn’t what it used to be, or fuel economy has plunged
• Vehicle backfires

If you need a new catalytic converter, it can be replaced with an original equipment part if it’s available, or an aftermarket converter can be welded into the exhaust pipe.  It’s not uncommon for oxygen sensors to need replacing as well.  The technician will also check for other problems in your powertrain that may have contributed to your converter failing.

Check to see if an emissions test is required where you live.  If it is, you will have to have a properly functioning catalytic converter to pass it.
