Why Alignment Matters (Vehicle Alignment Maintenance)

It's one of those things that can happen on a multi-day road adventure or a quick trip to the grocery store.  You hit a pothole, go too fast over a speed bump, nail a curb.  When it happens, you think, "I wonder if that was hard enough to do any damage?"  But things seem ok and you continue on your way.  Keep in mind that any blow to your vehicle's suspension can throw it out of alignment.  It can be a hard knock from the road or from another vehicle, such as being involved in a minor accident.  When your suspension is out of alignment, it means that the wheels aren't all pointing where they should.  And after a while, it can make your tires wear unevenly and cause problems with steering and handling. Let's go back to that pothole or curb you hit hard.  Even though you think there was no damage done, if you wait until you see tire wear, you may need to replace all four tires, not an inexpensive proposition. That's why it's a good idea to make sur ... read more

It's Brake Time (Brake Calipers)

Race car drivers have demonstrated the advantages of disc brakes, so most modern vehicles use them.  Sometimes just the front wheels have disc brakes, but many vehicles now have them all the way around.  A major component of the disc brake is called a caliper.  It works by squeezing brake pads against the disc or rotor, kind of like a bicycle hand brake.  The brake pads themselves are what contact the rotor, causing friction to build and the wheel to slow down, but it's the calipers that apply the pressure to the pads. Caliper design has evolved over the years, and there are two common types.  One is called a floating caliper.  It has one or two pistons on one side of the disc. When you push down the brake pedal, the piston or pistons in your caliper put pressure on that one side.  A mechanism connected on the other side of the disc applies pressure as well, squeezing your disc so the vehicle stops.  Floating calipers are less expensive since the ... read more

The Red Menace (How to Deal with Rust)

Rust.  It's worse if you drive in places that use salt on the roads in winter, or if you spend time driving near a body of salt water.  But any vehicle has to deal with rust after years on the road.  And it's not just that rust can eat away your vehicle's body and fenders.  It can be a real problem around your suspension, drivetrain or any place where there's metal. Rust takes its time.  You don't see it until it's already done its dirty work.  It can wreak havoc with your electrical system.  Sure, vehicle manufacturers do their best to keep it to a minimum, but especially with road treatments like brine around, their task is a difficult one. The one spot everyone notices is in the paint.  You see a little bubbling under the once-smooth surface.  By the time it bubbles, it's well involved in rotting away that spot of your vehicle.  You wouldn't believe how just a little thing can start the process on its way.  A stone chips the pai ... read more

What is a TSB? (Technical Service Bulletins)

If your vehicle had something in its design or production that the manufacturer had figured out had an unanticipated problem, you'd want to know about it. And you'd want it fixed. There is something that can help drivers with just such a scenario. It's called a Technical Service Bulletin, or TSB. Here's what a TSB is. Vehicle design and manufacturing is a very complex process. Aftrer every vehicle is introduced, the more units there are on the road, the more likely weaknesses in parts or design will start to show up. Automakers gather data on the issues and how best to fix them. Then they send out TSBs (usually in the first year of the new model) so technicians will know to look for those problems and what to do about them. There may be more than one cause of a problem with a vehicle so there may be more than one TSB for an issue. A TSB can be issued for anything from failing water pumps to strange noises to smelly headliners. A TSB and a recall aren't the same thing. A recall is issue ... read more
