i just reached 150k on my 99 tl. and lately i hear and feel like im driving on rumble strips when i slightly turn the steering wheel to the right. when i hit a pot hole or go over a speed bump, it sounds like something is rattleling on my left driver side. i put the car on a lift and took off the tire. i moved it left and right and it felt loose. i shook it up and down, and it didnt move. i did the same to the right side and it didnt feel loose in any way. anyone know what might be loose or broken?

 

Check the inner and outer tie rod end on left side

 

yep, the wheel shouldn't "jiggle" left to right, probably a worn out tie rod, probably $150 to do at a dealership, $100 at firestone, and $25 to replace it in your driveway if you have knowledge and the tools.
