Why does the steering wheel make noise when shaking in place in the Elantra?

[DelMaggie]

Elantra steering wheel noise when shaking in place can be caused by the following reasons: Noise from the shock absorber plane bearing: If a clicking sound occurs when lightly shaking the steering wheel in place, it is likely due to insufficient lubrication in the shock absorber's plane bearing. To confirm, open the hood and listen for the noise from the top of the shock absorber mount. If the noise is indeed from the plane bearing, applying some grease may help. If the noise persists after greasing, replacement is necessary. Noise from the stabilizer bar: If the noise is not from the shock absorber, check for looseness or damage in the stabilizer bar bushings. Loose or damaged stabilizer bar bushings can cause noise not only when turning the steering wheel but also when driving on uneven roads. Looseness can sometimes be fixed by adding shims, but damaged bushings must be replaced.
