What condition does not typically cause steering wheel shimmy?

Steering wheel shimmy is often caused by factors that directly affect the wheel's balance, alignment, or the condition of the steering components. Worn shackle bushings primarily impact the suspension system and contribute to an unsteady ride or vehicle tracking issues, but they do not typically manifest as a shimmy in the steering wheel itself.

In contrast, out-of-balance wheels can lead to vibration at certain speeds, resulting in a shimmy felt through the steering wheel. Incorrect alignment causes the tires to wear unevenly and can result in pulling or wandering, also contributing to steering wheel shimmy. Likewise, worn tie rod ends can introduce play in the steering system, leading to vibrations or shimmy during driving.

Thus, while various conditions can cause steering wheel shimmy, worn shackle bushings are less likely to result in this symptom compared to the other conditions listed.
