Dentro de los muchos que hay en este foro no encontre uno con estos términos (eso si, estos estan en inglés), ojala les sirva.
2WD
2WD is the normal transfer case position selected when driving on the street and highway.
2WD Low
2WD Low is an optional low range kit for the NVG 231 transfer case that disconnects the front drive output inside the transfer case offering the slow control of 4WD Low with the turning capabilities of 2WD. This is particularly useful when on tight trails that have limited turning radiuses.
4WD High
4WD High can be selected for all wheel traction at higher speeds (20-45 mph).
4WD Low
4WD Low is selected for slow moving traction and control. This is the gear generally selected for trail driving and rock crawling.
ABS
Anti-Lock Brake System is a factory installed option on many vehicle which uses wheel rotation sensors to provide input to the vehicle computer and a control box. The system is designed to prevent wheel lockup during panic stops and when slowing down on slick surfaces.
Air Down
To lower the air pressure in the tires to improve off-road traction.
Anti Sway Bar
The anti sway bar (commonly referred to as ‘sway bar’) prevents body roll and keeps the vehicle from swaying back and forth at highway speeds, this gives car-like handling characteristics. When off-road the sway bars will reduce articulation unless they are disconnected
Approach Angle
When viewed from the side of the vehicle, this is the angle between the ground an a line running directly to the lowest hanging part on your vehicle (usually the front bumper). This is the maximum angle that a vehicle can climb without hitting the front bumper or other component.
Articulation
Articulation refers to suspension flexibility that allows the vehicle tires to remain in contact with the ground while driving over uneven terrain.
Axle
The completed assembly of differential, shafts, bearings and seals necessary to transfer power from the driveshaft to the wheels.
Ball Joint
Ball joints mount the steering knuckle to the axle assembly inner C-Yoke, or to the IFS control arms. Ball joints allow the knuckle to pivot when steering the vehicle.
Back Spacing
The measured amount in inches from the inside mounting surface of the wheel to the inside lip of the wheel. Less backspacing means the wheel will stick out further from the vehicle.
Budget Boost
An economical way to lift your vehicle by using spring spacers or shackles.
Bump steer
Bump steer is when a vehicle pulls or shoots off to one direction as the suspension is compressed or extended (when going over bumps in the road).
Cat/Catalytic Converter
An emissions control unit in the exhaust system that helps to reduce harmful vehicle emissions.
CB Radio
Citizen’s band radio allows an easy and inexpensive way to contact other vehicles when off-roading or in a convoy. They help to keep groups together and can be used to call out for help in emergencies.
Center of Gravity
The center position of balance of the vehicle from front to back and from the ground to its highest point. A lower center of gravity increases vehicle stability.
C-clip
The C-clip is used in Dana 35 and Chrysler 8.25” rear axles. The C-Clip is a retaining clip that holds the axle shaft into the differential carrier inside the axle housing. If the C-clip breaks or the shaft breaks, the axle shaft will be able to slide out of the vehicle. This can be very dangerous in off-road situations that are off camber, or vertical.
CJ
The CJ was the original open top four wheel drive vehicle capable of traversing just about any terrain imaginable. It first was introduced to the civilian market in 1945 and went through several model changes, some of which are the CJ-2A, CJ-5, CJ-7 and CJ-8. The last CJ model was produced in 1986 when it was replaced by the YJ Wrangler.
Coil Springs
An alternative to leaf springs for achieving desired vehicle height. Coil springs consist of multiple wraps of steel wire of a specific load rating.
Control Arm
The control arm is what holds the axle underneath the vehicle and keeps it located correctly under torque.
Crawl Ratio
The final low range ratio of your vehicle in 4WD low. This can be found by multiplying the transmission first gear ratio, transfer case low range ratio, and the axle ring & pinion ratio.
Curb Weight
The actual weight of a vehicle when loaded with fuel, driver, and passengers.
CV Drive Shaft
A common term used to describe a driveshaft with a double cardan joint to reduce vibration at steeper driveshaft angles on lifted vehicles.
Departure Angle
When viewed from the side of the vehicle, this is the angle between the ground and a line running directly to the lowest hanging part on your vehicle (usually the rear bumper). This is the maximum angle that a vehicle can descend without hitting the rear bumper or other component.
Differential
The differential transfers power from the driveshaft, through the axle shafts to the wheels. There are many different types of differentials such as; open, limited-slip, locking, etc. See Locker and Open Differential for more details.
DOM
DOM is the abbreviated name given to a specific type of steel tubing. Drawn Over Mandrel refers to the process that is used to manufacture the tubing. DOM tubing has superior strength and dependability characteristics compared to other types of tubing; specifically DOM is seamless.
DOT Approved
The Department Of Transportation must approve certain safety features of products (such as brake lines) if they are to be used legally on US streets and highways.
Drag Link
The drag link connects the pitman arm to the steering knuckle and enables the vehicle to turn via the steering wheel.
Drivability
This refers to a vehicle’s ability to drive under certain conditions, such as highway, off-road, gravel, dirt, etc. The main issues that are pertinent to drivability are: handling, steering, and ride quality. Depending on the modification, some aspects of drivability will be altered.
Driveshaft
The driveshaft transfers power from the transfer case to the axles.
Driveshaft Angle
The driveshaft angle is the angle that a driveshaft must be at to connect the transfer case to the axle. On lifted, short wheel base vehicles (SWB) the driveshaft angle can often be quite severe.
Full Float
An axle design where the vehicle weight is supported by a spindle and wheel bearing assembly. The axle shaft is used only to transmit power to the wheel through a drive flange or lockout hub assembly.
GVWR
Gross Vehicle Weight Rating is the maximum amount that the vehicle can weigh with full fuel, passengers and gear. This number is provided by the vehicle manufacturer and must not be exceeded.
High Center
High centering happens when all four wheels are off the ground and the vehicle is resting on its center skid plate. A high clearance skid plate like the TeraFlex BellyUP can help to reduce this problem.
