Did a search... two things are going on with my A4.

One is when at a full lock on the steering wheel (i.e. parking...) I get a clicking noise from the front. This is going slow; full lock left or right of the wheel. I am thinking tie rod here...

Second is a vibration that I feel more when accelerating at highway speeds... here I have no idea. Could both be related?

All help is greatly appreciated.

Prolly it is a tie rod.
Vibration might be also caused by your wheels.

I could have the wheels looked at... less than 6k miles since putting on new tires and allginment though...

check your tires and get an alignment. the alignment willtell you if you need to replace any suspension components
