1. An SUV manufactured in a different country than the one in which it is sold
   An SUV designed and manufactured by two companies
2. A large SUV that rides like a compact car

1. Inside the engine
   Inside the transmission
2. Inside the power window mechanism

The automatic transmission owes much to the planetary gear system. It uses planetary gears to change gear ratios without having to shift different gears.

1. A small metal disc that expands and contracts in a vehicle's air conditioning system to regulate freon pressure
   A small round plug that acts as a safety "valve," popping out if the coolant in an engine freezes, preventing the engine block from cracking
2. A metal valve found on the underside of a vehicle's body to allow ice and snow to escape, preventing rust and corrosion
   A small aluminum plug found in the radiator for emptying frozen coolant

Freeze plugs — also known as core plugs — are small metal plugs that are found in an engine block's channels that carry coolant. If the coolant somehow freezes, because it is too diluted or only water has been used, freeze plugs are supposed to "pop" out of their channel to allow the excess pressure of expanding frozen water to escape. In theory, this will prevent an engine block from cracking due to that excess pressure.

1. Engine mounts
   Suspension system
2. Trunk hinge
   Leather softener

Jounce is associated with a vehicle's suspension system. Specifically, it refers to the motion that compresses a vehicle's spring, strut, or shock absorber. When you go over a speed bump, the first motion compresses the suspension components. That first motion is jounce.

1. The three types of engine mounts
   The different valve timing adjustments
2. The alignment of your vehicle's front end
   The three ways to adjust your headlights

Caster, camber and toe are adjustments to a vehicle's front end. Toe is the difference in the distance between front tires, front to front and rear to rear. Camber is the tilt of a tire in relation to the ground. Caster is the angle of the steering mechanism of a vehicle offset from its vertical axis. Whew! All of these adjustments affect how your vehicle handles and how its tires wear.

A beater car (or truck) is a vehicle that has no redeeming value other than to get you from point A to point B. It is not pretty and probably needs lots of work (body and repairs). There are additional words to describe beater cars, but we can't use them here. Just sayin'.

1. Inside a manual transmission
   As part of the exhaust system
2. Beside a heat exchanger in the cooling system

1. Joule and ounce
   Juke and flounce
2. Jolt and bounce
   Jump and pounce

Jolt and bounce equal jounce. Engineers are a funny lot. Not much at concocting words, eh? Some would argue, however, that the word existed long before it was used to refer to vehicles.

1. The bonnet
   The deck lid
2. The front flap
   The upper lift

Bonnet is another term used for a vehicle's hood. In simple clothing terms, a hood and bonnet are nearly the same thing. Hence their interchangeability when referring to the hood of a vehicle.

A rumble seat was a seat located where the trunk is today. The reason for its name is pretty self-explanatory.

1. There is no separate frame from the body
   The body is cast from a single sheet of steel or aluminum
2. The fenders are welded to the body, rather than attached with screws, nuts and bolts
   The front and rear bumpers are made of rolled steel or aluminum

A vehicle with a unibody construction has no separate frame from the body. The metal structures are formed in a way that when welded will provide the necessary structural rigidity to the body and support to the vehicle's mechanical components, like the engine, transmission, axle structures, etc.

   They're talking about an axle that is not being driven by a power source, such as output from a transmission or a transfer case.
2. What they're really referring to is the center shaft of a turning pulley.
   They're pointing out the main shaft that runs through the center of a transmission.

A live axle is an axle that is being driven from a source of power, such as the output from a transmission or a transfer case. This is opposed to a dead axle, which is not being driven, but is free-wheeling.

1. One of the main metal shafts that connect the wheels to the power source, like a transmission or a transfer case, sometimes called an axle
   The main metal shaft that connects the transmission to the rear axle to move the rear wheels
2. The main metal shaft that moves the intake and exhaust valves from open to closed, repeating this several times per second
   The main metal shaft connected to the piston by a connecting rod that takes the piston motion and transforms it into a spinning motion to power a vehicle's motion.

The crankshaft runs the entire length of the engine, taking power input from the pistons and transforming it into a spinning motion. This is usually connected to a transmission and forms the motion that eventually is transmitted to the wheels to make a vehicle move.

1. Nope, the camshaft is the main metal shaft that connects the transmission to the rear axle to move the rear wheels.
   No way! The camshaft is one or more metal shaft(s) that moves the intake and exhaust valves from open to closed, repeating several times per second.
2. Yup! Just another word for the main metal shaft connected to the piston by a connecting rod that takes the piston motion and transforms it into a spinning motion to power a vehicle
   One of the main metal shafts that connect the wheels to the power source, like a transmission or a transfer case, sometimes called an axle

An engine may have one or more camshafts. These move the intake and exhaust valves open and closed to properly aerate the combustion chamber and allow exhaust gases to escape.
