Looking in my 1960-64 Ford parts book, I verified something I had read online. Sure enough, there was a fairly significant amount of play in the idler arm, and at least 1/8 inch of in-and-out movement at the tire. As Smokey might say, however, I had been asking the car the wrong questions therefore, I jacked up the passenger wheel under the control arm, left the driver’s tire in contact with the ground, and yanked on the tire with a snapping motion in an attempt to avoid any movement at the driver’s tire. A notoriously weak part from the factory, the piece on my car had been replaced in the past, and I never noticed any play during my time underneath the car. When I got home from a recent 100-mile trip on the expressway, I reconsidered the idler arm. I also give both front wheels a hearty shake at 12 and 6 and 9 and 3 almost any time the car’s on the jack. It must be said that I own more home alignment equipment than most do-it-yourselfers, and I keep a close eye on that sort of thing. I’ve driven the car in this condition for a couple of years, but I have noticed that the right front tire has had an odd wear pattern on its outer edge. As I previously mentioned, it was no longer frightening to drive, but also not something to which I’d throw a stranger the keys and say, “See what she’ll do!” Therefore, after driving the T-Bird on pins and needles for a year, I replaced the steering box with (two) rebuilds, new solid mounts, and a new rag joint, in addition to replacing many of the suspension components such as ball joints and bushings. It’s usually worse in one direction than another (right in my car’s case), and the steering gear is usually blamed – something along the lines of the spool valve, etc.
1965 FORD THUNDERBIRD IDLER ARM DRIVER
When referencing a 1961-1964 Thunderbird’s behavior, however, it occurs when a light steering input rewards the driver with a lurid, abrupt lane change that becomes more lurid and abrupt as speed increases. Smokey Yunick, more accustomed to NASCAR Chevelles than slow, heavy cruisers, might scoff and say that oversteer is a loose ass end, or something else comically vulgar.
Those who have followed my previous COAL updates on my 1963 Thunderbird may recall my problems (that those in the Thunderbird world label “oversteer”) with the steering system. Unfortunately, we all fall into this trap once in a while, and that statement definitely includes DIY classic car owners and perhaps even the engineering staffs of Big Three automakers.
It’s been awhile since I’ve read Smokey Yunick’s entertaining, colorful, and seemingly endless autobiography, but I recall his depreciating those who relied on what he called “cut and try” methods in lieu of analytical thinking and the use of data.
