Default Should I Replace My Idler Arm?

I have the engine out of my '74, gonna drop in a fresh one after the holidays. "While I'm At It" syndrome has kicked in; I want to replace at least the a-arm bushing and tie rod ends, and lop a half a loop(maybe a full loop?) off the coil spring. I figure I'll call Wilcox and get a complete USA made front kit. How can I tell if the idler arm needs replacing as well?

They are easy to change at any time..so that's the good part. I'd inspect it for play. If there is ANY movement in it or tie rods they need changed.

The idler arm takes a lot of abuse and some headers are real close to it and bake the lube.

Yeah it has headers. I'll just go for it.

Default Agree

Agree, I always buy the whole front end rebuild kit for a couple of hundred, plus a little more for the deluxe kit and be done with it. Likely have replaced some good components this way, however, you are not saving much money doing this piecemeal. While you have it all apart, it makes too much good sense to me to go back all new since the extra money is nominal I think given the labor is significant. My 2 cents.

BTW, for what it is worth, cutting one coil off the bottom of the spring on my 68 454 lowered the front about 1-5/8". Easy to cut too much. Hope this might help.

Thanks, I'll do a half coil and drive it a bit first. I want to come down about 2" but I'll sneak up on it.
