There are 25 car parts that start with the letter J. From Jabberwocky Gear to Junk Yard. Car parts refer to the various components that make up a vehicle, each playing a crucial role in its overall operation and performance. These parts can range from essential functional components like engines and transmissions, to auxiliary parts such as belts and hoses. The proper maintenance and timely replacement of car parts are vital for ensuring vehicle safety, efficiency, and longevity. With advancements in technology, many car parts now include electronic components, enhancing their functionality and enabling features such as automated driving systems and improved infotainment options.

An interesting fact about car parts is that many vehicles contain around 30,000 different parts, and the automotive industry is continuously evolving with new materials and technologies. For instance, lightweight composites are increasingly being used to improve fuel efficiency, while high-strength steel remains a staple for structural components due to its durability.

Here’s what each of the columns in the table means:

Descriptions

Jabberwocky Gear
A critical component that ensures the smooth operation of the ‘jabberwocky’ system, which helps the car navigate uneven terrain and obstacles with ease. Jailbreak Valve”
Jack
A mechanical device that is operated manually or hydraulically to lift a vehicle so that servicing or inspection can be performed underneath.
Jackshaft
A short shaft that connects the crankshaft to the transmission or other power-transmitting components, allowing for a more compact engine layout.
Jam Nut
A jam nut is a secondary nut that is tightened against a primary nut to lock it in place and prevent it from becoming loose over time due to vibrations or other forces.
Jaw Clutch
A jaw clutch consists of two sets of interlocking teeth that can be engaged or disengaged to connect or disconnect the power flow between the input and output shafts.
Jet Pump
A type of fuel pump that uses the Bernoulli principle to create suction and draw fuel from the tank, then pressurizes it for distribution to the engine.
Jet Pump Impeller
The jet pump impeller is a rotating component within a jet pump that uses the Venturi effect to create suction and increase the flow of the pumped fluid.
Jet Turbine
In a jet turbine engine, the turbine blades are driven by the expanding gases from the combustion chamber, which then drive the compressor and generate thrust for propulsion.
Jet Valve
A valve that regulates the flow of fuel from the fuel system into the engine’s intake manifold, ensuring the proper air-fuel mixture for efficient combustion.
Jewel Bearing
Jewel bearings use synthetic rubies or sapphires as the bearing surface, offering extremely low wear and friction characteristics compared to standard ball or roller bearings.
Jiffy Lube
A Jiffy Lube is a chain of automotive service centers that specialize in fast, convenient oil changes and other routine maintenance tasks, often with no appointment necessary.
Jiggle Pin
A jiggle pin is a metal pin with a pointed end that is used to temporarily hold parts in place during the installation process, ensuring proper alignment before permanent fasteners are installed.
Jockey Pulley
Small pulley that applies consistent pressure on the alternator belt, preventing slippage and maintaining the proper belt alignment
Jockey Wheel
A small pulley that applies tension to the alternator or accessory drive belt, maintaining proper belt alignment and preventing slippage.
Jockey Wheel Bearing
The jockey wheel bearing allows the tensioner pulley to freely rotate as the timing chain or belt moves, maintaining the proper tension and alignment of the system.
Joint Boot
A flexible, protective covering that encloses the universal joint or constant velocity joint, preventing the entry of dirt, moisture, and other contaminants.
Jounce Bumper
A jounce bumper is a rubber or polyurethane cushion that is installed between the vehicle’s frame and suspension components to limit the travel of the suspension and protect against damage during extreme compression.
Journal Bearing
A type of bearing that uses a thin film of lubricant to separate the rotating shaft from the stationary bearing surface, minimizing friction and wear.
Journal Bushing
Journal bushings are cylindrical bearings that are press-fitted into the engine block or other components to support the rotation of the crankshaft or other rotating shafts, reducing wear and friction.
Joystick Controller
Input device that uses a stick-like lever to detect the driver’s steering inputs and translate them into signals sent to the power steering system
Juicer Pump
Centrifugal pump that draws coolant from the radiator and pushes it through the engine block and cylinder head
Jumper Cable
Thick, insulated cables with clamps on each end that allow the transfer of electrical current from one battery to another
Junction Block
A centralized connection point for multiple electrical circuits, allowing for the safe and organized distribution of power throughout the vehicle’s electrical system.
Junction Box
Sealed enclosure that houses multiple wiring terminals, fuses, and relays to manage the flow of electricity to various vehicle components
Junk Yard
A facility that collects and stores damaged, abandoned, or used vehicles, which are then dismantled, and the parts are made available for purchase at a discounted price.
