so i have a 2004 4 door 4x4 blazer and it keeps killing idler arms. i am also getting a vibration or shake at 60-70 mph. i know the shakes are a common problem with this truck but im just wondering if anyone has found a answer. now with the idler arm slaughter, i just dont get it i got it aligned after i put it on but it only last a week,any insight on this matter? thanks in advance

 

Improperly installed, off brand parts, something else must clearly be worn out to be causing part failure so quickly. Check the pitman, tie rods. I had no shimmy or issues on my S10 after/before lift. I know our gear boxes are junk but that wont cause that part to wear out so fast. Do you have pictures of the arm?

 

your truck is amazing!
