2000 K2500 7.4L I finally got the old ones off, but I cannot get enough bolt thread on the new ones to go on. The bolts are the same length. I loosened the sway bar brackets. The frame is jacked up, but I cannot compress the lower a arm and stabilizer bar together. What am I doing wrong? it looks like the new bushings are holding me up. When I took the old links off there was 1 inch of thread showing past the nut. This has to be compressed, but how?
