This course will prepare students to diagnose and repair front and rear-wheel drive manual transmission systems, clutches, drive lines, differentials, and CV axles. Various gear designs will be studied, including helical, hypoid, bevel, and straight cut gear systems, and their influence on ratio calculation and torque multiplication. Overhaul practices such as teardown, measurement, inspection, repair, and reassembly will be covered. Four-wheel drive systems, including automatic locking hubs, transfer cases, and electronic drive-train systems, are also explored to prepare students for the A3 Manual Drive Train & Axles ASE Exam.
