If your talking the big cast piece that's part of the steering knuckle, no, its not replaceable, unless you go with an off road companies piece, big $$$. If it's worn bad enough, you can have it welded and machined back into spec.
Otherwise, the keepers, the bolts, the pieces that fall out when you disassemble, there easily replaceable.
Can you post a pix? We can easily identify if its repairable or not
