Tighten up loose, wandering steering with the Mevotech Supreme Steering Idler Arm (MK6259T) — the front-right idler arm that supports the center link on your Astro idler arm setup. It's a direct-fit replacement for the 1985-1990 Chevrolet Astro and 1985-1990 GMC Safari, pivoting opposite the pitman arm to keep the steering linkage level and steering response consistent.
On a parallelogram steering system, a worn idler arm lets the center link sag, which shows up as excess play, uneven tire wear, or a vehicle that wanders and needs constant correction. If a failed idler arm is the cause, this unit restores proper location of the linkage.
