What does the greaseable socket do?

The greaseable socket allows you to periodically add fresh grease. This helps to flush out contaminants like dirt and water that can cause corrosion and wear, extending the life of the ball joint.

How does the cover plate help?

The patented cover plate is pressed into the ball joint. It acts as a seal, keeping dirt and debris out of the socket, which minimizes bearing wear and promotes longer service life for the component.

Do I need to replace these in pairs?

It's generally recommended to replace ball joints in pairs on the same axle. This ensures even wear and consistent handling characteristics between the left and right sides of your vehicle.

Product Details

If you're noticing looseness in your steering or uneven tire wear on your 1990-1997 Mazda Miata, it might be time to replace the front upper ball joints. These components are crucial for connecting your suspension control arms to the steering knuckle, allowing your wheels to pivot for steering while keeping the suspension working correctly. Worn ball joints can lead to sloppy handling and premature tire wear, so replacing them is key to getting that tight, responsive feel back.

Moog builds these ball joints with a focus on durability and ease of installation. They feature a patented cover plate that helps keep dirt and debris out, which means less wear on the internal bearings and a longer service life. The ball stud itself is heat-treated to meet or exceed original equipment standards, helping to prevent early failure. Plus, the Belleville preload washer helps maintain a tight bearing package as the joint naturally wears over time, keeping play out of the steering.

This ball joint also has a greaseable socket. This is a practical feature that lets you flush out contaminants and add fresh grease periodically, which really helps reduce corrosion and wear. It's designed to fit right, so you can expect an easier installation process and accurate steering alignment once it's on your Miata.
