Trickle Down Technology

Recently, Nissan introduced the latest version of its Leaf, the company's electric car. It has many new features, including something called e-Pedal. It allows the driver to let up on the accelerator and, unlike a gasoline engine car, the Leaf doesn't just slowly lose speed; letting off the throttle pedal brakes the car in a very controlled way, using regenerative and sometimes friction brakes. With practice, a driver can go for a fairly long time without touching the brake pedal.

Another system, similar to those found in self-driving vehicles, can steer the car to keep it in the center of the lane using a camera and radar. It literally watches the lane markers and, of course, doesn't work well in snow that obliterates those markers. But the technology is impressive and can greatly reduce fatigue on long trips.

In fact, much of this technology has "trickled down" from research on autonomous vehicles, such as adaptive cruise control that slows down your vehicle (even to a stop) if the vehicle in front of you decelerates or stops. And we can expect these features will eventually find their way into all price levels of vehicles if the past is any indication.

There was a time anti-lock brakes were only found on premium vehicles; now they are on nearly all new vehicles. Traction and stability control are also prevalent, helping drivers reduce slippage and maintain control, thanks to computers.

With SUVs and trucks so popular, rear backup cameras help drivers see behind their tall back ends, reducing injuries, deaths and property damage. Bumper sensors and cameras allow drivers to be visually and aurally aware of their surroundings with 360° protection.

Many of these features improve our vehicle's safety and efficiency, and we can expect new technologies to crop up in the future. But just like the mechanical systems in your vehicle, it's important to maintain the electronic and computerized systems. Technicians at Lakeside Certified Auto constantly train to keep up on these latest developments. Make sure all your vehicle's components are maintained in top condition.

When Metal Meets Metal (Wheel Bearings)

What part of your vehicle has little metal balls inside that are lubricated and allow you to cruise on down the road?  They are wheel bearings, and automotive designers might argue they are human beings' second greatest invention of all time (the first is, of course, the wheel!).

You have a wheel bearing at each wheel.  They allow your wheels to turn freely, minimizing friction that would ordinarily slow you down when metal meets metal.  When one of your wheel bearings starts to go bad, it lets you know. A wheel bearing does its work quietly when it's in good health but starts getting noisy when it isn't.  People describe the noise differently.  Sometimes it sounds like road noise, a pulsating, rhythmic, sound.  That pulse speeds up when your vehicle speeds up. 

Here's what's happening when you hear that sound.  As mentioned, the bearing has these little metal balls inside a ring.  They have a lubricant inside to reduce friction between the balls; modern wheel bearings are sealed and they're intended to do their job without any maintenance. 

Wheel bearings take a beating; you hit some rough potholes or go over some uneven railroad tracks. Sometimes water can get into a bearing and reduce the ability of the lubricant to do its job.  Time starts to take its toll, too. When the lubricant isn't reducing friction like it should, the bearing can heat up. One of those little balls can start shedding pieces of metal and soon those shards start grinding up the other balls.  Friction takes over and soon your wheel isn't turning smoothly. That's what's causing the sound.  If a wheel bearing is not fixed, it could eventually seize up completely, and you can be stranded.

It's a lot easier if you heed the early warning signals, that pulsating noise.  Now, sometimes a similar noise can be caused by a bad tire, but in either case, it's important to have it checked out. Our Lakeside Certified Auto technicians will be able to tell you fairly quickly what the problem is and offer a solution.

Wheel bearings generally don't fail often and usually last from 85,000-100,000 miles/140,000km to 160,000km. But consider them a long-term maintenance item that, once fixed, will keep you heading smoothly to the next destination.
