includes a special tool to remove the bushing
in the
lug , leaving a larger lug hole.

to the bolt .
42. Place the tip of the bolt and the shouldered end
of the tool into the bushing from either side.

easier to apply the tool from one side or the other.

causing the tool to drive the bushing out of the
lug .

and the tool are not re-used.
