I've got a '99 4X4 and the right sawy bar link snapped. I ordered ACDELCO replacement parts kit (2 links) figuring that if one snapped the other can't be far behind. I was able to get the link and bushings in place but can't compress the bushings enough to thread the nut. So far the end of the link is flush with the bottom of the lower bushing washer. My question: Is there a special tool or secret to compressing the bushing to thread the nut?
