Uniball UCA - A Upper Control Arm with a spherical ball joint that allows for greater range of motion than the stock ball joint, which is limited in it's range of movement.
LT; Long Travel - A 'kit' that has longer UCA's, CV's, Tie Rods. This basically widens the front track to gain wheeltravel. LT suspensions are used for high speed desert running.
TRE - Tie Rod Ends.
CEL - check engine light, sometimes refers tocode that cuased light that can be read by a code reader
DS- Driver's side
DS: Drive Shaft=shafts that carry power and torque from the engine/tranny/xfer case to the axles.
DC DS=Double Cardan Drive Shaft=a pair of joints in a drive shaft that allows the tube to move in various directions and angularities.
Diffs - Differentials: found in the front and rear axles that consists of gears that transmit equal power and torque even if they rotate at different speeds.
EGR = Exhaust Gas Recirculation valve
EWD or WD - Electrical Wiring Diagram, (part of FSM set)
FSM - Factory Service Manual. The "bible" as published by the manufacturer. Used to guide in repairs
Land Cruiser Prado - A 120 series Toyota SUV which the FJ Cruiser shares many mechanical parts and structure.

JDM- Japan Domestic Market- Refers to items particular to vehicles manufactured and sold in the Japanese market.
Items include but are not limited to:
Power retracting mirrors
Dual air conditioning
Adjustible shocks
Winches
and various cool and some gawdy accessories.
LB/FT - pound feet of torque
LB/IN - pound inches of torque
LHD (Left-Hand Drive): steering wheel on the left side, driving on the right side of the road
MAF - Mass air flow sensor
MIL - Malfunction Indicator Light (same as a CEL)
NA - Naturally Aspirated - An engine that is not turbocharged nor supercharged
OBDII - On Board Diagnostics Port available on ALL cars sold in the US 199 and later. Allows a common intercface tool to be connected to read and reset engine fault codes (CEL). Many Autpart stores will read your code for free vs. paying the dealer.

1GR-FE= 4.0 Liter V6 used in the FJ Cruiser
ABS - Acronym for Anti-lock Braking System. This system uses a computer to control your brakes on your car by applying and releasing your brakes quickly to prevent skidding or sliding from occuring.
ATRAC; also A-TRAC - Automatic Traction Control. Uses the ABS system as a traction aid by activating the brakes to "lockup" the wheels momentarily to create traction.
VSC - Vehicle Skid Control. This applies the brakes to modulate high speed manuvers (e.g. a slippery, ice-strewn road) to keep the FJ Cruiser from loosing traction due to excessive speed or sudden loss of traction.
DAC- Downhill Assist Control. This applies the ABS system to 'crawl' down steep, loose terrain with a minimum of sliding or loss of control. Activated by a dash switch while in 4Lo
CDL Switch- Center Differential Lock Switch- Switch installed to allow the Center Differential to be locked when the transfer case is in High. The actual Center Differential Lock is in the Transfer Case.
A-TRAC Switch- Activates the traction control for slow speed, offroad use.
Rear Locker Switch; RR Locker Switch - This locks the rear differential so both rear wheels rotate at the same speed no matter what.

OEM - Original Equipment Manufacturer. (Toyota in this case)
OME - Old Man Emu. An Australian four wheel drive specialty manufacturer that makes all kinds of cool stuff that causes us to empty our billfolds.
PCV Valve - The Positive Crankcase Ventilation valve is an emissions control device that routes unburned crankcase blowby gases back into the intake manifold where they can be reburned.
PM - preventive mantenance
PM - private message
PO - Previous owner
POS - Piece of S#1T

PSI - Pounds per square inch - A measure,emt of pressure.
RHD (Right-Hand Drive): steering wheel on the right side, driving on the left side of the road.
RPM - Rotations Per Minute
SOA - Sprong Over Axle - A suspension lift for a leaf (Vs 120 series coil) spring suspension. It places the leaf springs on top of the axle vs the bottom.
