In my never ending quest to basically rebuild the T100 (LOL)Im pretty positive my idler arm is bad.
If you jack up the frontend and grab a tire at 9 and 3 you can wiggle (more than Id say is normal) it a bit and hear a small clunk. The following is newer or good: Steering box, pitman, center and drag links, TRE's. The idler is about 3 years old maybe?
If I take a prybar and place it between the frame and the idler and grab the wheels the clunk is gone. The clunk def sounds like its coming from the idler arm as well. When driving down the highway the more bumpy the road is the more the truck wants to wander as well as vibrate slightly, specially over bumpy roads.
So idler arms bad or what?
