PITMAN ARM?

what wears out on a solid piece of steel? the conical hole for the draglink tapered end? splines on the sector shaft hole?

2x idler arm/center link/tie rods/BJ wear out

4x4 the drag link/tie rods/BJ wear out...the steer arm & pitman arm are solid steel

only time I have saw a difference was 2x or 4x4 and power or manual steer

not counting the pitman arm/steer arm for 4x4 lift kits.

you can check with them for replacements or lift arms if in need. skyjacker/rough country/JC Whitney
