Factory idler arms - unservicable?
#1
The upper pivot bushing on the '71s idler arm has a good 1/4" of play in it, so I purchased a replacement bushing to push into it.

Then I proceeded to remove the lower bolt, and found the following, which looked unlike any other idler arm I'd seen online. No castle nut, and the bolt wouldn't move for anything.

It looks as if there are chewed up threads:

This surprised me, so I went to look at the '72:

Hello...you look familiar.

Same thread oddity and divot at the bottom. Unless I've missed my guess, these are swaged at the bottom, rendering the bushing non-serviceable; correct?

They are not built to be serviceable, the Ford manual says to replace the "complete idler arm assembly".

However, if I had the correct bushing I would probably give it a try, by removing it from the car, and use a nut breaker to remove the nut and then use a die to clean up the threads.

Too much effort and risk taken in trying to service a part that could result in a nasty failure. I'll get a replacement, serviceable idler arm instead.

You'll need a shop press to r&r the bushings. I ground the swedged portion, then replaced the nut and used red locktite to retain it.

Yes, I installed it upside down, and then realized it after the locktite set. Much easier to order a new one from west coast classic cougar.
