ive never replaced one. i dont know if i gotta buy an idler arm or just the bushing or what, its got a wobble in it and it scared the bejesus out of me today it just started shaking the whole car after i greased all the bushings, (on a right turn)

 

nevermind, it was fix a flat that caused the problem cant belive the product is still sold,neverthe less i guess it still helps the stranded motorist as it did myself
