Bear trucks recent trouble

alright ive been using my bears for aaaages on my 9two5 and there great i have 2 venom barrels and ive never had a problem.....i just got my lacey and i thoguht id chuck my bears on for some freeride to try it out...what first happened was i couldnt get any threads on my kingpin to put my nut down. i then probably made it worse and forced it on and it was obviously to tight then it started making this really squeeky noise but not in my pivot cup it was like it was my bushings any help?
