: : This week I went on my first tour in my A. Things went fine until we turned off the paved road on to a oiled dirt road. My A immediately started to shake. The shake would first start with the steering wheel and proceed to "feed" on it self until the whole car would shake violently. I had to stomp the brake and slow down to about 5mph to get it to stop shaking. A young fellow that has a reputation of being very knowledgeable found my wishbone? loose and tightened it. NO LUCK. Then they checked my kingpins, they were ok.
James, my car had the same exact symptoms! I wrote tech. editor at mafca... no response. It turns out the would-be "resorer" from whom I bought the car had cheaped out on the radius rod socket and bolt kit. The bolts and springs that hold the lower socket over the radius rod ball were missing the shims/spacers/bushings that keep springs at proper tightness/loosness. Replacing these bolts/springs/spacers with proper ones from a Model A parts house solved my problems! Good luck! --Mike pS Without the spacers, there isn't wiggle room for the radius ball in the socket on rough roads... the radius rods will start to bend and twist sending jello-gelatin shaking through the whole car!
: : The road was a little washboard like, but very little since it was oiled red dirt. Shake would occur about 30 seconds after I would reach 20 to 25 mph.

: : Several folks said their steering wheels shook also on the same road but theirs did not "grow" into a total vehicle shake. Most of the A's just drove on down the road at 30 mph without any trouble.
: : My steering wheel has a little play but it drives on the highway just fine.

: : What about the steering shock I see advertised?
: : Where should I look first?
: : thanks, james shotwell

: ........I went thru the whole 9 yds here abt week or so ago see if you can find it.. There are lots of think that will cause shimmy.. Yes the steering dampers do work but I would like to see you find the real trbl. I couldn't find the trbl and no one else could either on my new 74 ford pu so I put a damper on it and it waas fine. Man said if I hadn'y been so cheap and ordered power steering the cylinder would have dampened it.. ha ha oh well..I run 650-16s so use damper as insurance and also a panhard bar..from AC&R......
