Re: S-10 Ideler arm
What brand of idler arm are you using? If it is a cheape type get rid of it and replace it with a moog type arm they are about the strongest one made. I would also reccomend checking your pitman arm. If there is any side to side movement replace it. If this arm is bad it will take out the idler arm. Having idler arms loose on a GM IFS is very common. This is true on the s-10s and the full sizes. They normally last only about 20,000 mi max on a stock vehicle. If you add in a lift and bigger tires it dramatically reduces it life expectancy, espicially on the s-10's.
