Wheel Bearing Replacement Cost Guide

Most bearing failures are the result of simple wear. Ideally, if the manufacturing tolerances were good and the seals effective, wear is minimal and very slow. Excess wear on the bearings can occur if a vehicle is overloaded; causing the bearings to run hot and break down their lubricant – leading to more rapid wear. … Read more

Serpentine Belt Replacement Cost Guide

The function of a serpentine belt is very simple: it transmits engine power from the crankshaft to the driven accessories. Typically, those would be the water pump, the alternator, the AC compressor, and the power steering pump. Some engines have fewer things while others (such as diesel engines) have more. The serpentine belt is held … Read more

Idler Pulley Replacement Cost Guide

An idler pulley is basically a pulley housing with an integral sealed bearing pressed in. The purpose of the idler pulley is to facilitate the serpentine belt routing – either to route it around an engine obstruction or to wrap the belt around an accessory pulley more fully in a way that improves its bearing … Read more

Universal Joint Replacement Cost Guide

A  universal joint or u-joint is a cross-shaped casting with short even-length arms, and cups with needle bearings fitted onto the end of each arm. It is packed with heavy grease for lubrication and often has a grease fitting to allow regular servicing. The bearing cups press into machined holes in the driveshaft and component … Read more

Spark Plug Replacement Cost Guide

Every gas engine uses spark plugs to fire the air-fuel mixture, as the end-point in the ignition system. A spark plug screws into the cylinder head on each cylinder, and has a pair of contacts on its end. The ignition system coil sends a high voltage spark across the contacts at the appropriate time, which … Read more

Knock Sensor Replacement Cost Guide

The knock sensor is an essential component of the engine management system, there to detect and manage spark knock. Spark knock is what happens when an air/fuel mixture ignites too early, or if the fuel is too low octane (which allows it to burn too quickly), or if the combustion is uneven leading to colliding … Read more

Camshaft Position Sensor Replacement Cost Guide

The camshaft position sensor does pretty much what its name implies – it senses the exact position of the rotating camshaft and it provides that data to the PCM. From there that information is used, along with data from the crankshaft position sensor, to manage ignition and injector timing. In addition to that, on modern … Read more

Crankshaft Replacement Cost Guide

If the engine is the heart of a car, the crankshaft is the heart of the engine. It is the primary moving part to which the pistons and connecting rods attach, which drives the transmission on one end and the camshaft and accessories on the other. To replace the crankshaft the transmission has to be … Read more

Electronic Throttle Body Repair Cost Guide

An electronic throttle body is basically a cylinder that intake air flows through, with a rotating plate in the middle that can open or close to allow or block airflow. It’s a part of the engine’s air intake system, sitting where the carburetor sat on older design engines. The first throttle bodies were similar in … Read more

PCM Replacement Cost Guide

The PCM is the main computer module the vehicle uses to run the engine management systems and control vehicle emissions. The PCM directly controls the fuel injectors and the coils, determining the fuel mixtures and timing based on sensor inputs and it’s basic programming. “PCM” stands for “powertrain control module”, which is used interchangeably with … Read more
