Out of Joint (CV Joint and Boot Replacement)

If you have a front-wheel-drive vehicle, it has components called CV joints which enable you to turn your wheels smoothly. The CV stands for “constant velocity.” In essence, it’s a set of gears that connect a shaft that allows power from the transmission to be sent to the wheels.  When you turn the wheels, no matter what angle, the input velocity rotation will be equal to the output. Thus, the name, CV (constant velocity) joint. Other vehicles with 4-wheel drive and all-wheel drive also use CV joints.  

If one of your CV joints isn’t working right, you may find your vehicle difficult to handle.  If one breaks, your vehicle may stop moving.  So, it’s important that CV joints be in top working condition.  The joints need a lot of lubrication, so they are surrounded by grease.  There’s a rubber enclosure around them called the boot which holds the grease in and protects CV joints from the elements. 
 
The biggest problems come when one of those rubber boots cracks.  Water and dirt can then get into the joint, causing it to wear down and lose all its vital lubrication.  It’s important to have your CV joints inspected regularly so a technician can spot cracks before the CV joints are ruined.  Sometimes just the boot can be replaced before any major damage is done.  But when the joint does go bad, it must be replaced.  

Signs your CV joint needs changing out? You might hear a clicking sound when you turn if the CV joint is worn out. You might notice some thick, black grease around your wheel or on the pavement where you park your vehicle.  You might also feel your vehicle vibrate when you’re going fast.

If you suspect you might have a bad CV joint, bring your vehicle in so a technician can determine what’s going on.  Keep your CV joints in good shape and reduce the risk of them seizing up at an inopportune time so you can avoid being stranded.

Muffler: Victim of Winter (Muffler Repair)

So you almost got through the winter until, one day, your muffler started sounding like a dragster, loud and obnoxious.  It's not surprising.  All that road salt and brine can cause rust to punch holes in a muffler, and that should raise a big, red warning flag about the safety of your vehicle.

One big concern is carbon monoxide, a poisonous gas that can drift into your cabin if your muffler is leaking. You've probably heard about people whose home furnaces have leaked carbon monoxide and overcome families inside.  Carbon monoxide can first cause you to feel dizzy and nauseous.  It can even render you  unconscious—even kill you.  So if your vehicle's muffler is leaking that gas, well, it's nothing to mess around with.

Oh, and how about that noise? You may get a ticket since many municipalities have laws against noisy exhausts. 

Your muffler may be making a clunking or rattling sound when the engine's running or it may be spewing thick exhaust smoke.  All of these symptoms are telling you to get to your vehicle service facility soon.  A technician may find it's the muffler or another part of your exhaust system that is coming apart or is busted. 

Sometimes the repair can be as simple as replacing a section of pipe or clamps, but sometimes you'll need to replace more components.  Your service advisor can recommend several different options to try to help you meet your performance and budgetary needs. 

You'll drive out with a vehicle that doesn't sound like a teenager trying to hotrod the family car, is a whole lot safer and sounds a lot less obnoxious in the process.

More than Pads and Rotors (Brake Caliper Replacement)

You might be familiar with brake pads and rotors, two components of your vehicle's brakes that have to be regularly serviced.  Here's another important component of your brakes: the calipers.

Calipers are used in disc brakes, the type of brakes now found in most recently manufactured vehicles.  A caliper is the part of the brakes that squeezes the brake pads against the discs, or rotors, which turn with your wheels. 

There are different kinds of calipers, but the basic principle is the same.  You press down the pedal, brake fluid activates a piston or pistons that squeeze the brake pads against the disc and the friction slows down your vehicle.

While modern vehicles have a warning system to let you know it's time to get your brakes checked, your brake light usually goes on when your fluid level is low or your fluid pressure is low.  But you may have to look out for signals your calipers are the problem. 

If your vehicle pulls to one side when you brake, that could be a sign that one caliper isn't working right.  If you smell a burning odor coming from a wheel after a trip, there might be too much pressure from a caliper.  Grinding or squealing when you brake is another signal that it may be time to bring in your vehicle so we can check your brakes.

One way to minimize brake issues is regular inspection.  Have them periodically looked at when you bring in your vehicle for an oil change.  The good news is brake issues are more likely to be caused by pads or rotors wearing out.  Calipers last a lot longer, but even they will need replacing every so often.

H20 No! (Driving Through Standing Water)

In a year marked by unusually heavy flooding in North America, drivers are very aware of the possibility they may find themselves driving where water has come over the road.  It can be a daunting and frightening situation.  Flooding waters can move quickly and unpredictably, so you have to keep your wits about you when you encounter that situation.

Here a sample of one vehicle manufacturer's guidelines on what to do.  First, the vehicle is designed to go through some water, but you must be careful.  Never attempt to drive through water deeper than the bottom of your tires.

You can get out of your vehicle to check the depth of the water, but you can never be sure that you aren't going to drive into a spot where the road has washed away.  You can't see below the surface of the water, and suddenly you could find yourself in a place where the road drops off unexpectedly.  In swift moving storm runoff, your vehicle could literally be floating away with the current, putting your life and those of your passengers in mortal danger. 

Never go more than 5mph/8 km/hr when you drive through standing water.  That minimizes the waves you create.  If you DO find yourself in water that is touching your drivetrain components, that water can damage them.  And if you get water in your engine, it can lock up in seconds and stall.  The potential damage can be catastrophic.

You may have found yourself driving in water deep enough to reach your drivetrain components, and it's essential that you have a technician check the fluids to make sure they haven't been contaminated.  That includes engine oil, transmission and axle.  Driving with fluids contaminated with water can severely damage those components. 

The bottom line is to avoid driving through water at all if you possibly can.  Check your vehicle's owner's manual to see if there are specific guidelines for driving YOUR vehicle in standing water.  It's information that could save your life.
