Okay guys tried searching but I don't think the threads I found were really what I was looking for. My steering worked fine the entire time I had the truck up until I went wheelin the first time. After that I killed the idler arm and had to replace it, no big deal, easy job. Steering was fine for another 2 months until it happened again (after going wheeling again) so I replaced it last night (wheeling was sunday) with a Moog arm this time. Put it back together and MOST of the vibration is gone but a couple times on my way to work it came back for a minute. I had to get on the gas to get whatever the issue was to go away. Any ideas on what it could be? It's not in the steering wheel itself, so no rag joint. It couldn't be the stabilizer right? Any help is much appreciated. Also if it means anything to you guys when the vibration starts the truck wants to go left every time.
