ASE PS2 Test Preparation Guide: Driveline Components
● CONSTANT VELOCITY (CV) JOINTS — Used mostly in front-wheel drive (FWD) cars but also many four-wheel drive (4WD) and All-Wheel Drive (AWD) vehicles that allow the operating angle of the joint to change without affecting the speed of the shaft or wheel. Basic types include Rzeppa, crossgroove, double-offset and tripod. Rzeppa, crossgroove and double-offset
ASE PS2 Test Preparation Guide: Automatic Transmission/Transaxle
● AUTOMATIC TRANSMISSION — A transmission that shifts itself using engine RPM, load and other inputs to regulate shift points and gear engagement. Late model automatics have electronic/hydraulic controls operated by the Powertrain Control Module (PCM) or its own Transmission Control Module (TCM). Most late model automatics have five or six gears (speeds), though some
What’s Your Belts & Hoses IQ?

ASE PS2 Test Preparation Guide: Automatic Transmission/Transaxle
The major components of an automatic transmission are the torque converter, pump, clutch packs, gear sets, valve body, shift solenoids, control module, filter, fluid and fluid cooler.
ASE PS2 Test Preparation Guide: Drivetrain Components
The major drivetrain components include the driveshaft, universal joints, differential and axles on rear-wheel drive (RWD) cars and trucks, and the halfshafts, constant velocity joints and hub assemblies on front-wheel drive (FWD) and all-wheel drive (AWD) vehicles, and transfer case on four-wheel drive (4WD) trucks and SUVs.
ASE PS2 Test Preparation Guide: Fuel System
The major components in the fuel system include the fuel pump, fuel filter, fuel lines, fuel injectors, fuel pressure regulator, throttle body, fuel tank and gas cap.
Brake Fluid Q&A
By Andrew Markel Editor, Brake & Front End 1. What are the fundamental differences between synthetic fluid and conventional DOT 3 and 4? Simple, it all comes down to the base stock. Both synthetic and conventional brake fluids start from the same “polyethylene glycol” stock. But to make synthetic brake fluid the manufacturer will “synthesize”
Bearing Q&A: The Ins and Outs of Bearings
On a typical passenger vehicle weighing around 3,400 pounds, each pair of front-wheel bearings, as well as the rear-wheel or axle bearings, support around 850 pounds, depending on the weight balance and driveline configuration.
