I have a 2002 Tahoe 4WD with 68K miles. I've been experiencing side to side sway when driving at moderate speeds. The Tahoe seems also particularly sensitive to road depressions, getting even more sway. A few years ago I put on 20" chrome rims w/ Yokohama Geolander tires that seemed to improve the handling quite a bit over the stock tires. The tires now have about 38K miles and have maybe another 5K to go. I tow a 5K lb boat and have put on approx. 5k miles towing it. I'm still on the stock suspension and am thinking this might be the problem. Any advice?
