The lower suspension arms of the Minor pivot on a steel fulcrum pin isolated by rubber bushes. Failure of the bushes will cause both the pin SUS105 and the eyebolt SUS103 to wear, resulting in excessive play in the front suspension. Bushes are available in rubber SUS104 or polyurethane SUS104WB.
If the back end of your Sprite and Midget has a mind of its own, it may be time to replace the rear spring bushes. The rear end of the springs take eight bushes; four on the springs and four on the shackles. The original rubber bushes were AHA7182 but you can upgrade to polyurethane with SUS104WB.

The front poly bush is part AAA629POLY.
