GM\'s new Quadrasteer info I found The availability fo GM's Quadrasteer four-wheel-steering option has been expanded to include the 1500 extended cab and 1500 HD pickups. If you haven't experienced Quadrasteer it's worth a look. At low speeds the rear wheels turn opposite the fronts, which cuts down the truck's turning circle considerably. At highway speeds the rears and the fronts turn in the same direction, improving the pickup's high-speed maneuverability. Those of you who tow will really appreciate having wheels that steer near the trailer's tongue. The extended availability of Quadrasteer that reached deeper into GM's pickup truck line also includes some of the General's big SUV's, as 2500-series SUBURBANS and YUKONS XLs can be ordered with the four-wheel-steer option. Quadrasteer reduces the 4x4 sub's turning circle from 44.3 to 35 feet, a 21 percent improvement. (The Quadrasteer availability seems sorr of random --- offered on some big trucks but not others --- but a GM spokesman sxplained that currently it can be fitted only to DANA60 9 3/4-inch axles with leaf springs.) I typed this word for word from a magazine report.
