Steering wheel vibration question

[Brian83]

So I have a steering wheel vibration I'm trying to track down. It's an up and down vibration that's worse while accelerating between 20-40mph. And by vibration I mean the steering wheel jumps up and down. I've checked everything on the front end and it's tight, new tie rod ends, unit bearings spin smooth, new axle u joints. Rebuilt the front drive shaft a year ago. MC track bar a year ago. Adjustable LCA, factory Uppers. Any suggestions on what would be causing an up and down vibration? Nothing side to side at all.

Have your tires been balanced recently? Out of balance tires can cause excessive vibration both horizontally and vertically

I'm running CounterAct balance beads. And would a tire out of balance cause localized vibration like that vs shaking the entire jeep?

At certain frequencies it could. As you accelerate, you likely go through one or more periods of resonance, and it just happens to resonate through the steering column.

If the balance beads aren't distributing right away, that could potentially be a cause. They might start out as a clump but then distribute as you accelerate causing it to smooth out. Are your tires also balanced with weights?

Is the vibration mild or violent? High or low frequency? Is it visible or only noticeable by feel?

Loose motor/trans mount man. Likely it’s the front left motor mount under the steering shaft.

Sorry for reviving an old thread.

Did you ever get this figured out? I have the same issue after installing an SYE kit, new driveshafts and both front and rear UCAs.
