Front suspension rebuild

  • After rebuilding front end the drag link is making contact with starter when turning wheel all the way to right. Replaced all tie rods, drag link, Idler an bracket an had front end alignment, any suggestions on possible cause.

  • 1st thing to come to mind is compare old and new idler arms and the center link for shape, bends, etc.

    did you do the work or someone else? Could it be upside down or wrong application?

  • I did the work, followed all torque specs, assembled according to manual, was supposed to be assembly line originals, purchased from J. D. Larson ( all classic motors)

    Maybe the wrong idler arm, people say Manuel an power are the same what’s your opinion on that.

    Manual and power steering idler arms are definitely different, however the pivot mounted on the frame is the same. There is no way to invert the drag link as it would not fit onto the pitman arm upside down. The power steering idler arm has a much larger bushing to help the steering return to center after a turn but the offset is the same. The tie rod ends on the passenger side are the same for both manual and power steering.

  • Which idler arm has metal teeth, power, manual or both.

    I will need to check when I return home, but I believe that both have the teeth.

  • I checked my NOS idler arms that I have in stock. The manual steering arm does not have the teeth but the power steering version does.

  • Thanks Fred,

    The idler arm that I was using has teeth, I have one without teeth, hopefully that fixes my problem, I will post results.

    Being as you have both idler arms, it will be easy to compare the bushings. The power steering version has a noticeably larger bushing than the manual steering version.

  • After changing to manual steer idler arm everything turned out fine, I’ve been told the power steering idler arm should have worked but for some reason it presented a problem.

    Any way all is fine now, going for alignment soon I’m thinking or should I say trying for 2positive on caster, .5 or .75 negative on camber an 1/16 - 1/8 on toe in. I’m open to suggestions if anyone knows a better setup.

    Thanks,
