+1 to replace all four. May as well get the wet bolt kit while you have it off. Yes go up one rating level. That might add a leaf or different steel just get the rating. I went from 3500 (pair) to ~4000 and it rides better than ever.

This..on last 5er I had, I replaced all four 3500# spring pack's with 4K spring packs, went to MorRyde suspension and replaced old shocks with Monroe severe duty shocks and that took care of all of it..no wondering or worrying,
