I have a 1996 Pathfinder 4 wheel drive with 120,000 miles on it that has a "sway" problem. The sway can occur at any time but usually on the highway (at any speed). The body starts rocking side to side and if the speed is maintained, it gets gets worse. Letting off the gas or increasing speed will make it stop. The truck has new shocks and struts (adjustable suspension feature) but the problem has not improved. The front end was just aligned and checked for suspension wear. Tires have been balanced and rotated. Has any one else exhibited this problem or have any ideas?
