Question: do all toyota 4runners have 4 wheel drive

Answer: No, Because the drive train was still developed from the same source, the available engines were identical: The same 2.4 L four-cylinder (22R-E) and 3.0 L V6 (3VZ) engines were available in rear-wheel-drive and four-wheel-drive layouts. The new 4Runner used the independent front suspension that had been developed on the previous generation. The older style gear driven transfer case was phased out on the V6 models and they now had a chain driven case. The older gear driven case was retained on the 4-cylinder models.
