{Chrysler 300} RE: lower control arm bushing

Now this makes me scratch my head…

A friend who does a lot of racing just email me a document from MOOG in 1999 that is a sizing and cross reference page for control arm bushings with their sizes. My 1969 Moog catalog show that for 1960 to 1964 Chrysler is K-317.

The one for the early 1960’s Chrysler’s is highlighted. It shows the OD as 1.688. If that is the case, then the interference fit is supposed to be .185! Am I brain farting on my math as that is a lot.

The part in the shop is 1.520.

Subject: {Chrysler 300} lower control arm bushing - Problem

Hi All,

This hobby is getting less fun as more and more of the simple things are becoming a whole day affair.

I went to press in my lower control arm bushings on the ’64 and they will not go.

The control arms are all bead blasted, painted and ready to go save putting in the lower control arm bushing and its associated big pin. I tried to use the press and right away it did not feel correct. I pulled it out and tried it by hand with a hammer to get it started and it still did not want to go in.

I have the Chrysler – Miller special tool for it.

I then measure the bore on both control arms, and they are 1.502 to 1.503 in diameter. I then measure the bushing and it is 1.518 to 1.520 inch. The difference is over .015 inch!

I would expect .002 to .004 at the most for an interference fit. But 0.015 inch? It will never go in. WTF?

Of course, if I got back to the seller of the front-end kit, I would get the, “…I have never had anyone complain…” horse dung.

Anyone recently do lower control arms on a ’63 or ’64 and have a manufacturer and part number that works?

Thanks, James
