Lower Control Arm Rebuilding

Thanks for the information. Some clarification please. If using Poly bushings if I understood the bushing sleeve stays in the lower arm. Should they be replaced or are the originals sufficient? Using specialitiy tools from American Racing I got 1 out easy enough. Just wondering if the old one is OK to go back in or should both be replaced before the poly bushings and lower arm pivots go in. Should the pivots be changed also or are the old ones good enough. Now is the time to change them if needed.

Thanks again.
