i replaced my pitman arm on my '94 C1500, the other day. fine. well, now my steering wheel is off by 90 freakin' degrees . since there are 4 splines that are larger than the rest, the arm can only fit on one way and still point to the center link. plust, i marked the sector shaft before i removed the old arm. i'm thinking the autozone pitman arm may have the splines cut wrong or something. even a few degrees would make a difference, considering how narrow the sector shaft's range of motion is (90 degrees maybe?). i wish i'd compared the splines on the two shafts before i stuck the new one one. ideas? did autozone give me a messed up part? i've done a few pitman arms for friends and family and never had this issue before. i don't feel like ripping the thing back out and taking it back, but i will if i have to. thanks.
