remove A arm and remove balljoint
remove old bushings & shaft
disassembled
screw in one bushing
screw shaft into bushing
screw in 2nd bushing
next the balljoint
use the grade 8 bolts
install back on truck
tighten everything up & grease
Some tips. Screw in the first bushing all the way into the A arm. then after greasing the shaft, screw it all the way into the bushing, then unscrew it out one turn. Then screw the other bushing into the A arm. Snug them down good. I have seen the bushings tack welded to the A arm, just be sure to tack them so they can be removed later.
There may be other ways to do this, but this is how I've done it over the years. If anyone has anything to add please feel free.....eb
