95k on one original wheel bearing, other went to 160k. Factory uca ball joints were still good when I did the lift at 90k. Right lca ball joint is still original with 200k on the clock and still going. Left lca ball joint was replaced at 185k. Original idler/pitman arm made it to 90k (front end was leveled on 33s) and never could get them to last till I put the exaxt kit on. After that, pitman arm lasted 50k and idler arm now has 75k on it with no slop
