We retained the stock steering linkages with no modifications other than installing the optional BDS dropped pitman arm (PN 083402). Buy or rent a pitman arm puller. Once you have a good deal of tension on the puller, give it a couple of gentle, yet firm, raps with a hammer. The pitman arm should pop right off. If you’re in the salt belt, you may need to grind a groove clear through the factory arm to relieve the tension on sector shaft.
