Support your front steering linkage with the Mevotech Supreme Idler Arm MK6331, built around patented sintered bearings and a serviceable SAE grease fitting. It fits many vehicles, among them the 1988-1991 Chevrolet C1500, 1988-1991 Chevrolet K1500 and 1988-1991 Chevrolet C2500. See the "Vehicles it fits" section for the full list.
A steering idler arm supports the end of the center link opposite the pitman arm and lets the linkage pivot as the wheels are turned. Mevotech's Supreme design focuses on durability and easy service:
A worn idler arm on the 1988-1991 Chevrolet K1500 can cause loose or wandering steering, extra play at the steering wheel or uneven front tire wear. If the idler arm is the cause, this direct-fit replacement for the listed applications replaces it. Inspect the rest of the steering linkage before you replace parts, and have the alignment checked after installation.

What does an idler arm do?
It supports the end of the steering center link opposite the pitman arm. It lets the linkage pivot as you steer, so the front wheels can turn together.

Yes. An SAE grease fitting is included, so the idler arm can be lubricated during routine service.
What are signs an idler arm may need replacing?
Common signs include loose or wandering steering, excess play at the steering wheel and uneven front tire wear. Diagnose the cause first, because other steering parts can cause the same symptoms.
Should I get an alignment after installing it?
