What is the benefit of a greaseable ball joint?

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

How does the gusher bearing design work?

The gusher bearing is a metal-to-metal design where grease can flow through the bearing surface. This continuous lubrication helps reduce friction and wear, contributing to a longer lifespan for the ball joint.

Does this ball joint come with any hardware?

This product is for the ball joint itself. It's recommended to refer to the manufacturer's installation instructions for a complete list of required hardware and any specific installation procedures.

Product Details

When you're tackling suspension work on your Chevrolet Trailblazer, GMC Envoy, Isuzu Ascender, or other compatible vehicles, a worn ball joint can make steering feel loose and imprecise. This front upper ball joint from Moog is designed to replace your old, worn part and bring back that solid, responsive feel to your steering. It's a key component for keeping your wheels properly aligned and your ride stable.

Moog builds these ball joints with a gusher bearing design. This means it's a metal-to-metal setup where grease can actually flow through the bearing surface. This helps reduce friction and wear, especially when combined with the Belleville preload washer that keeps the bearing package tight as it wears. The ball stud itself is heat-treated to meet or exceed original equipment specs, which helps prevent premature failure. Plus, the patented pressed-in cover plate seals out dirt and debris, further protecting the bearing and reducing looseness over time.

This ball joint is also designed for an easier installation. Moog uses precision tolerances so it fits right and helps make steering alignment straightforward. The socket is greaseable, allowing you to flush out contaminants with fresh lubricant, which is a good practice to extend its life. This part is a solid option for restoring your vehicle's steering performance.
