Hmmm....Am pondering this too for mine
How did the shop figure out it was the idler arm that needs replacement? Just curious, I want to understand how to diagnose it.
I am thinking of changing the tie-rod assembly and am thinking of tackling it myself....So If someone is willing to drop some pointers I am also in the market for some input.
