The GMC Yukon Transfer Case distributes engine power to both the front and rear axles, allowing the driver to select between sure-footed four-wheel drive and efficient two-wheel drive. Inside the Transfer Case, a chain or gear set transmits torque through different driveshafts. The high and low ranges magnify force for rock crawling or towing. In its earlier years, GMC models applied a floor-mounted lever that was tied straight to the Transfer Case. Later years combine the Transfer Case with a dash switch and electric motor that engages the gears with a tap. It also engages 4WD high at low rolling speed. There are essentially two styles, part-time and full-time. The part-time one lets the Yukon run in 2WD on dry pavement and locks the front driveshaft on slippery trails, while the full-time or AWD style uses a center differential or viscous coupling to allow the front and rear shafts to turn at different speeds without binding. The differences revolve around driver choice and internal coupling hardware. Nonetheless, both suffer chain stretch, gear wear, and noisy skips that warn GMC owners to fix faults before their Yukon is stranded and the Transfer Case quits.
