MOOG 81-87 Isuzu Pickup Front Upper Ball Joint

If you're working on the front suspension of your 1984-1991 Isuzu Trooper, this Moog K9042 front upper ball joint is a solid option. Ball joints are critical for connecting your control arms to the steering knuckle, allowing your wheels to pivot for steering while also handling suspension travel. A worn ball joint can lead to sloppy steering and uneven tire wear, so replacing them is key to keeping your Trooper handling right.

Moog builds these ball joints with a powdered metal gusher bearing design. This allows grease to flow through the bearing and onto the stud, which helps reduce friction and adds strength. The socket is also greaseable, meaning you can flush out contaminants and wear with fresh lubricant, extending its life. The housing is forged and has a larger cross-section in key areas, giving it more material for added strength. Plus, the hardened ball stud is made to handle the loads your suspension endures.

The dust boot on this ball joint has a patent-pending design with a Belleville washer to help manage both axial and radial movement. It also features a larger grease reservoir and a pre-tapped hole for a grease fitting, making maintenance more straightforward. This makes it easier to keep the joint lubricated and protected from corrosion and wear.
