Steering wobble @ low speed after right turn

On occasion, I experience a front end shimmy or wobble after a right turn only at low speed. Close the throttle and the car recovers.

Any ideas where the problem cause lies?

Thanks...
 
Make sure the spring shackles are not binding and are lubed. check the wheels for true , roundness, and tightness.
 
Racemo, that low speed shake is not that unusual. I have a centerdoor that did it when I hit a bump at a low speed. Turning the steering wheel hard to the left or right corrects the problem. Tighten the spindle bolts does solve the problem, but I think that is a temporary fix. I did examine the entire front end and have not yet found a real cause of the problem.
One of the parts suppliers told me that the front spring shackles were binding and causing the wobble. I have not yet pulled the shackles for a close examination.
 
Put me down for the tighten the spindle bolts. I have driven my speedster for 7-8 years plenty of miles and about once every season i retorque the spindle bolts . Fixes the shimmy every time....
 
I re-did the ENTIRE front end with the exception of one part. That 1926 coupe at any speed would go into a death wobble. I mean 1/2 turn on the wheel back and forth until you came to a complete stop. Take off from there and she was happy until it decided to scare the crap outa you again. I even did the shock absorber thing from the tie rod to the axle. Replaced all 4 tires and tubes, front wheels, rims and bearings too... Made NO DIFFERENCE. It was in fact the worn out wishbone ball/socket on the pan.
Changed the alignment to a drastic negative caster "At Will". ws
 
Thanks a bunch guys. All your suggestions have good logic. I look forward to performing each one, one at a time. I want to see if I can learn something and assist others.

First try the wishbone ball/socket on the pan as y.m. Bill says. just a tiny bit of movement makes A LOT of difference at the other end, after any changes there you must recheck the toe-in as it changes that A LOT also.
 
Racemo,
Also check that the pitman arm is tight, and check the yoke or U bolts that hold the front spring to the frame.

Thanks again to all.

I do believe I have too much wear clearance in the pan ball socket. The springs on the ball studs are bottomed out and I detect movement when forcing with a large screwdriver.

Cheers :)
