OK, here's the deal... I installed a new NAPA track bar thinking it would solve my clunking issue. I didnt. . now, it's getting worse... much easier to make it clunk. It now makes the noise going straight, over the slightest imperfection in the road, while turning and at any speed (4mph included!) . I'm getting scared to drive it, not knowing what the culpret is. My next guess is the steering box, as I can feel the knock comming up thru the steering column. Underneath, nothing is obviously loose... . I put a wrench on everything I could, including the Ranchos. Best guesses, guys?? I have a TDR meet in one week, and I wont drive this thing til it's fixed! HELP!!
