Steering
Remember : there are many different places where you can have play , to find the problem : wheels aired up to 40 #, grasp the tires @ 9:00 & 3:00 and try to move back & forth , if you feel play , crawl under the truck and move them again while looking for loose parts , often tie rod ends and the horizontal ' drag link ' off the steering drop arm ~ it has heavy springs in it that often break , I highly recommend using used drag link springs , the new ones from China suck .
After these loose points are fixed , then grasp the front tire @ 12:00 and push & pull it , always some play here , look at the gap between the brake drum and the brake backing plate , there shouldn't be play there , if there is , it's time for a routine wheel bearing service where you remove the outer bearing , clean it well with LINT FREE rags , pack with black Moly based grease and re - assemble , snug up the adjusting nut as you rotate the wheel , do not preload the nut , back it off one notch to fit the cotter pin if neccessary & use a new cotter pin every time or be ready to DIE

.
The stering box has a plug on top of it , often a Zerk fitting but never ,
EVER use grease ! use gear oil , the thickest you can find , or fill it with STP engine honey .
To adjust it , you'll need a 90 degree flat blade screw driver and a BOX END wrench ~ DO NOT use an open end wrench here ! .
As mentioned before : when new , these trucks steered *very* easily ~ almost like power steering so if it's stiff , work at greasing it and adjusting things , make sure the tires match size and brand etc. .
