For New Owners/Newbies On this page, the underside and the underhood of a TJ are shown and some major parts were named. I explained what they do in a nutshell. If you learn them, they will help you understand the technical information available on www.DailyDrivenTJ.com.
Underside
Under the hood
Transfer of Power Engine -> Transmission -> Transfercase -> Axle -> Wheels
Anti-Sway Bar and Anti-Sway Bar Link Keeps the body square with respect to the axle. It is also called anti-roll bar. Without it, the Jeep's body will lean/sway significantly more during curves and/or turns.
Axle/Differential (Front and Rear) Turns the wheels. Differenctial allows different speed of wheels tied to an axle. Ex. When the jeep makes turns, the outer wheels spins faster than the inner wheels, the 'open' differential makes the transfer of power smoother by transfering all the power to the wheel with the least traction. This often creates problems during offroading. To overcome this issue, 'lockers' are installed to lock the differential which eseentially locks two wheels (left and right) to spin at the same rate either going straight or turning (or even when one wheel is air-born).
Brake Caliper Holds brake pads and pushes them against the rotor/disc.
Catalytic Converter It converts carbon monoxide into carbon dioxide.
Control Arms Holds the axle under the frame rail while allowing vertical movement.
Drag Link Connected to steering knucles on both side of the axle and drags the wheels left or right.
Driveshaft (Front/Rear) Transfers power from the transfer case to the front and rear differentials.
Exhaust Pipe (As labeled in the picture above) Routes exhuast gas toward catalytic converter.
Emergency Brake Line This is a physical line similar to bicycle brake, just tad bit thicker.
Fuel Tank In TJs, the fuel pump assembly containing fuel level sending unit, the pump, filter is one piece and stays in the fuel tank.
Muffler Muffles the exhaust noise.
Oil Pan Holds Engine Oil.
Power Steering Gear A component of power asisted steering system that actually steers.
Pitman Arm A connection between the drag link and the power steering gear.
Radiator This keeps the engine cool. Automatic transmission vehicles often have transmission cooler built into the factory radiator.
Skid Plate Protects catalytic converter and transfer case.
Starter Starts the engine. Spins against flywheel when engaged.
Trackbar Centers the axle under the jeep (left & right), attached to the frame rail.
Transmission This is where the gear shifting occur.
Transfer Case This allows 4 wheel drive.
