72 Duster Resurrection
The uppers in this kit i screen shotted come with new press in outer shells only because it looks like that one LBJ upper arm already had the old ones completely pressed out. Its a shame they did that. Prothane sells a kit where you burn the rubber out leaving the outer shells intact, then just grease up and hand press in the new poly inserts and inner sleeves. Its much cheaper. Like half the price.
The lowers in this kit are just the poly inserts just like the uppers could have been if the shells werent knocked out. Basically using a good gas torch, you heat up the rubber bushing releasing it from the lower control arm mounting shaft pin, and releasing it from its outer shell. Then remove just the rubber part of the bushing from rhe arm. Yes this is messy and smelly, so do this where you dont care about a mess, and away from any fire hazards.
What you end up with is a lower control arm with the pressed in outer shell from the old bushing still intact pressed in the arm, and the mounting shaft pin. When it all cools down simply grease up the polyurethane insert and press by hand into the lower control arm, and grease and reinstall the mounting shaft pin, and reinstall the lower control arm in rhe car.
