Vibration source?

Thanks Jerry. All tires were just rebalanced. I'm looking to use a Currie Johhny Joint to replace this. I think it looks more robust plus greaseable
Johnny Joints aren't available for use as tie rod ends. Currie's (Rock Jock) Currectlync HD Steering Kit does include heavier-duty greasable tie rod ends but they're only usable for that kit.
