We sandblasted the LCA before removal of the shaft and bushing. Just Suspension carries the American Muscle line of suspension tools. This tool (bottom left) makes removal of the LCA shaft a cinch. When the shaft is removed, the rubber bushing is cleaned out and the outer shell stays in place. Then the poly bushing and shaft slips in with some grease. The greaseable LCA shaft and poly bushing (top) is a Firm Feel Inc. exclusive product.
