Idler bushing help

So I hear this knocking sound in the steering... I jack up da truck and the idler bushings on the pass side are gone.. the arm that goes up into the idler arm bracket is basicly floating.

I searched the internet and cant find that bushing for the top and bottom. Anyone know where I can find em or ideas as to why they disentigrated to dust? LOL

youll just have to buy a new idler arm.

Dats what I did... Went to da local parts store and dropped 119 bones a whole new idler arm and slapped it on... took a whole 20 min to change it! I am rollin again! ROFLMAO! Dats why I love B22's, theyre so damn easy to be sleezy!
