i took off 891s and put on 600lbs hd iron man 4x4 springs still does it.. annoying.. my links bushings are all good, new 5100s.. im perplexed.. pck has been on there since i got it.. i carry a lot of weight but it shouldnt sway.. id like to know what ppl did to make it go away... wheel scales to see what ea wheel is weighing and see if shock is strong enough.. thats what im thinking.. with added weight the stock rated 5100s not strong enough to keep it from swaying.. i did have some slop, play in the passenger lower rear control arm.. but i welded a washer on ea side to take up any play. but still have swaying issue
