See if any of these are happening to your vehicle.  You feel it vibrating excessively underneath when it’s running, or you hear strange clunking, grating, or grinding sounds coming from beneath.  Maybe it’s hard to turn your vehicle, or you can hear squeaking when you’re going slow.  Perhaps you feel a shudder when you step on the throttle.  

Any of those could be signs that your vehicle’s driveshaft might need lubricating, and it’s important to have one of our technicians check it out. Your vehicle’s engine puts out a lot of twisting power.  That force is called torque, and the driveshaft is the part that handles the job of transferring all that torque from your engine to the wheels.  If it’s a four-wheel or all-wheel drive vehicle, it will have driveshafts front and rear. 

Some driveshafts have different segments which are connected by couplings called U-Joints.   So that everything can glide along fine, that whole assembly needs to stay well lubricated.  Our technician can inspect the driveshaft and U-joints to make sure there aren’t any broken or excessively worn parts.  

Many manufacturers recommend servicing and lubricating the driveshaft at certain intervals, and it’s important to keep on that schedule.  It’s essential because poor lubrication can lead to a failure while you are driving, possibly causing other expensive parts to fail.  Not keeping your driveshaft lubricated or failing to maintain it regularly is the top cause of driveshaft problems.

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.

When you feel your vehicle vibrating as you're driving down the road, one cause could be something you may not have ever seen: your driveshaft.  It is underneath the vehicle and most drivers don't climb under there to take a look very often.  The driveshaft is a cylindrical part that helps conduct the rotational power from your engine to your drive wheels.  If you have a four-wheel drive vehicle, you may have two driveshafts. 

The drive shaft has bushings, and when they wear out, that's a likely source of the vibrations.  When the bushings are in good condition, they prevent the driveshaft from vibrating.  And if you don't get your vehicle repaired fairly soon after discovering vibrations, they'll continue to get worse and cause other components of the drivetrain to wear out.

The driveshaft is, of course, only one part of the drivetrain.  It includes other parts such as axles, transmission, differentials and joints.  They all work together and need to be maintained properly.  When a driveshaft fails, there can be symptoms other than vibrations.  They include difficulty turning, rattles, clunks and squeaks coming from underneath your vehicle. You may even feel a shudder when you accelerate from a stop.

Driveshafts can fail when they get corroded or damaged by rough roads, curbs and debris. A trained technician with experience working on drivetrains uses specialized equipment that doesn't further damage the drivetrain's other parts.  Sometimes the entire driveshaft will have to be replaced; sometimes the problems can be fixed by replacing individual components. 

Your vehicle's drivetrain was engineered to propel you smoothly down the road.  When time and distance begin to take their toll, have your vehicle looked at by your service facility. They'll know how to properly pinpoint what's causing your problems and restore your vehicle to the reliable, smooth, safe machine its designers worked hard to create.

Some people love 4x4 vehicles, the true 4-wheel drive works of engineering like Jeeps and 4x4 pickups that allow you to seemingly go anywhere on the planet. You can climb up a 40-degree rock trail with some planning and skill (always careful to protect the environment, of course), or you can get through the deepest snow.

But with that added capability comes additional complexity, drive-train components and other systems that less capable vehicles don't have.  And that is why when it comes to 4x4s, you have to maintain them a little differently from those vehicles that spend their lives on pavement.  Here are some of the key things to keep an eye on:

• Transfer case—This transfers power from the engine to the wheels.  A transfer case has fluid in it that needs to be changed at intervals recommended by the manufacturer.  Your service advisor will let you know how often that is and will keep track of your service dates.  You will need to make sure the transfer case seal is working properly.  Otherwise, transmission fluid could get in and cause damage that is costly to fix.  Some transfer cases have an electric motor that shifts it through gears, and its connections are often exposed to the elements, making them vulnerable to damage and corrosion.  Proper maintenance will keep those connections working like they should
• Front and rear differentials—These also have to have the right amount of fluid and should be checked regularly.  Your service advisor can let you know when you need that fluid changed as the owner's manual recommends.  It's important the service is performed correctly with the proper lubricant so it will work the way it is designed to.
• Brake lines—Those 4x4s practically beg to go into wet spots. They also are great machines to conquer snow: road salt, brine and all.  Moisture, salt and brake lines are a recipe for corrosion, so brake lines need to be inspected regularly.  There are anti-corrosion sprays or white lithium grease that can retard corrosion.  Remember, getting there is half the fun, but not being able to stop is no fun at all.

So enjoy your 4x4 and what it can do that other vehicles can't.  Just remember that even though it's tough on the outside, it needs special care to keep it going.  Oh, and remember to take care of the environment when you go off-roading, too.
