Chrysler’s strong and simple front suspension remained virtually unchanged from 1962 to 1976. The basic layout for all the A, B, C, and E body cars is the same…the only differences are size differences. IE: some ball joint assemblies, torsion bar lengths and diameters, upper and lower control arms, strut rod bushings and tie rod ends. By 1973, the A body had all the same ball joints as the B-body. This standardization means that parts swapping is easy and the relatively long production runs mean that most of the parts are easy to get over the counter; in-stock or special order. I like dealing locally, and my parts suppliers here in the S.F. Bay Area can get me everything I need in Moog parts today, or within 48 hours. Check out your local jobber or NAPA and see what they have.
The one item that most frequently wears out is the strut rod bushing at the front of the K-frame. There is a bushing on the front and a bushing on the back side too…the one on the backside usually wears out first and is hard to spot.
Many times I have seen a brand new bushing on the front (easy) side of the K frame and in back is a shredded, pathetic little donut of rubber. If the vicim of such negligence is lucky, no harm has been done, yet. Most of the time the strut rod has begun to eat away at the K-frame, or bend, or get horribly notched, or all three. Shady repair shops try to get away with replacing just the front bushing because the procedure, by the book, looks menacing and they just don’t understand the whole torsion bar deal.One thing that mystifies a lot of people is the torsion bar. Think of it as a very long spring and you’ll get it. It works by twisting. With the ride height adjuster screw backed all the way out and the suspension in full droop the bar is easily removed. There are two ways to get it out and I am going to show you the easy way. By showing you this method you also learn how to replace both sides of your strut rod bushings without disassembling the front end hardly at all. You won’t even have to pull the shock absorber…well, in most cases.
