These are some of the frequently asked questions about driveshaft, axle and drivetrain noise.
Oxygen Sensor Heater Codes
An oxygen sensor code related to the heater circuit can be difficult to cure.
Dumb Thoughts About Smart Cars
Only 2 percent of accidents are due to vehicle component failure of degradation.
Porsche Tech Tip: TPMS
Porsche TPMS systems use four antennas mounted in the wheel wells and a designated module for the tire pressure. The sensors use a 433mHz frequency. On most models, the menu will have the option for two sets of tires and sensor IDs for summer and winter tires.
Electric Power Steering: Mating Electrical And Mechanical Diagnostics
Most electric power steering system modules are on the high-speed CAN network with the engine control, ABS and transmission control modules. Some vehicles will also include the body control module and other modules that are critical to the safety of the vehicle. These modules share a lot of data to make sure the driver does not notice when the electric power steering is working.
Alignment Specs: 2006-2010 Volkswagen Passat And 2009-2012 CC (B6 Platform)
The VW B6 Passat for 2006 was an entirely new design. It was followed by the coupe CC in 2009. The complicated four-link front suspension from the B5 platform with four ball joints was replaced with a cast-aluminum lower control arm and a MacPherson strut. In the rear, the Passat received an independent suspension with a trailing link design.
Measuring Brake Pedals And Pads
On a mechanical level, it is easy to understand how brakes work. We all understand that brake fluid transfers force from one hydraulic component to another. But, how does this apply to how a brake pedal feels? This is where math is required.
What DOT Really Means: The Do’s And Don’ts Of Inspection And Replacement
Brake hoses are the most government-regulated components on a vehicle. Anyone making brake assemblies must be registered with the Department of Transportation (DOT). All aftermarket hose, fittings and complete hoses must conform to FMVSS 106 and SAE J1401. These tests are demanding and often exceed what a vehicle will see in the real world.
Air Ride Leak Detection
To the untrained technician, a winter air ride problem might lead you down the path that there is a leak in the system. However, chances are there are no detectable leaks. These types of faults are usually set by parameters from the air ride module for a specific action to cause an expected result.
Brake Job: Jeep Wrangler
The Jeep Wrangler JK can be deceiving. If you look at the brake pads, rotors and calipers, it looks like just about every other truck. When you look at the front and rear suspension, it looks dated with a front live axle. But, don’t underestimate the JK because it has one of the most hydraulically sophisticated ABS and stability control systems on the market.
Alignment Specs: 2008-2017 Chevrolet Traverse, Saturn Outlook, GMC Acadia And Buick Enclave
The 2008-2017 Chevrolet Traverse, Saturn Outlook, GMC Acadia and Buick Enclave are all based on the Lambda platform and represent a large portion of GM vehicles. These vehicles can be front- or all-wheel drive.
Jeep Tech Tip: Lower Control Arm Cold Temperature Squeak/Creak Noise
The customer may describe a creak or squeak noise coming from the front suspension. The noise is typically more noticeable during cold temperatures below 40 degrees. The noise may go away when the vehicle warms up.
