Hello everybody I need help
I have found a part in my car steering assy. that it is obviously worn but I don't know the correct name for it to order a replacement I'd click on fast lane and they don't have a picture of it. I had the car on jacks because my steering wheel is shaking after 40 mph,I shook the tires while a friend held the steering wheel and there is side to side play on both front tires ,more so on the passenger side,remove the tire pass.side and check the tie rod ends and they are solid follow the tie rod to this part that is like an anchor to the chassis and connects the tie rods and the steering damper together on the passenger side of the vehicle this part obviously allows movement side to side for steering but is also moving up and down inside the bracket and I know that is not right and that is what moves when I shake the tires while holding the steering, what is this thing,what is it called I want to order the right part
thanks for your help

Idler arm is bolted to the frame and the other end is connected to the tie rods

Another question
Is it normal for this part to wear at 52,000 miles,I notice some surface cracks on the lower control arm bushings but thank God no play or sign of missaligment,also very small play in the wheel bearings, wich I adjusted ,the grease was that pretty green stuff so no sign of overheating or wear.Hope the Idler arm is the culprit cause I just order one repair kit for it and a new steering damper,there was a little oil on it.
Thanks again for the response
