Idler arms need replacement
Visitor, 1995 Chevrolet Astro
My astro is allwheel drive. I have two Idler-Arms and by design they operate in a slight bind. Iv'e replaced
both of them at once and the steering is precise again. The steering balls are on the idler-arm not on
the drag link as usual. They'er about $75.00 apiece.
