We have over 167K miles on our (actually, my daughter's) 2000 LS with no suspension problems.
Are you guys that are going through ball joints, tie rod ends, etc. running larger than stock wheels? Lowered? I would posit that the extra weight of the 18"+ wheel size is destroying the suspension components. The heaviest stock wheel/tire weight is ~49#. I know even some 18" wheels weigh ~40# sans tires. With a tire weight of almost 30# that's a lot of extra unsprung weight.
