1970 Sportsroof 302 2V, Dearborn, built June 17, 1970, power steering, A/C
I see that NPD sells upper and lower bushings for 1970 idler arms. Does it work well to replace these bushings and use the original idler arm vs. a complete replacement? I am trying to keep the original parts where possible.
As far as evaluating the condition of the bushings, my idler arm has no up and down play in it, but the bushings are weather cracked. Does the “return to center” bushing issue apply to power steering idler arms? If so, which bushing is supposed to be so stiff you cannot turn it by hand? I can turn my upper bushing (the end that attaches to the mounting bracket) by hand. Or is it the bushing on the other end that is supposed to be very stiff?
Also, the threads past the nut on the end of the mounting bracket that contains the upper bushing has raised marks that appear to prevent the nut from being removed. Can the bushing be replaced without removing these raised spots on the threads?
Thank you,
Barry
