Features:

  • Engineered to retain socket torque and smooth articulation over the life of the part, to maintain tight steering feel
  • Exclusive powdered-metal bearing design allows grease to flow through the bearing to the stud for reduced friction and enhanced strength and stability
  • Patented cover plate maintains low deflection and consistent socket torque
  • Greasable design for longer service life
  • Belleville washer maintains pressure on bearing to eliminate looseness and extend bearing life
  • One-piece forged housing for unequaled durability and strength
  • Premium polychloroprene sealed boot with a grease-relief valve
  • Full-ball hardened stud for consistent stud articulation throughout the life of the stud
  • Grease grooves for full lubrication between the housing and the ball stud

Your vehicle's ball joint is a flexible joint with a ball and socket type of structure that allows the steering knuckle to move up and down and pivot in response to steering input. The ball and socket typically wear from use and lack of lubrication, resulting in excessive up and down play along with possible noise, shimmy and alignment problems. MOOG Problem Solver parts are designed to do a better job than OE parts.

The unique design of MOOG ball joints along with MOOG's exclusive patented technologies ensures improved performance and long-lasting service. The greasable design of the joints allows lubrication to reach the bearing surfaces while flushing out contaminants. In addition, the ball joints feature a one-piece forged housing which provides unequaled strength and durability. The patented cover plate and Belleville spring maintain socket torque over the life of the joint, for tight steering feel.

MOOG’s reputation as “The Problem Solver” can be traced all the way back to 1937. That was the year the company first produced a front-end replacement part recognized by mechanics as outperforming the factory original. As years passed and MOOG® continued to innovate, the company became known for its ability to consistently develop “problem solving solutions.” Today, hundreds of innovations later, MOOG is recognized and respected throughout the automotive industry as The Problem Solver. It continues to earn that reputation by providing not only problem-solving parts, but award-winning technical support and training materials also.

Great Product
When I bought these upper ball joints I made a mistake. And I write this to keep others from making the same mistake I did. If you are a DIY kinda person, make sure your upper ball joints can be pressed out before buying. You may find you need to buy a control arm with ball joint. Which is the problem I ran into. If it has a snap ring on it. It can be replaced.

Just What My Old Pick-Up Needed.
The K9609 ball joint has made my old pick-up drive more smoothly. The old ball joint must have been more worn than I thought. It was an exact replacement of the original ball joint, just as CARiD indicated. Replacing the lower ball joint was more difficult than replacing the upper joint.

Exact Replacement Made The Job Easy.
The K9022 ball joint was an exact replacement for the failing ball joint in my old pick-up. That made the replacement very easy.

Problem Solved
I had play in my front end. To make sure that I eliminated any steering linkage, I purchased Moog problem solver outer tie rod ends, inner tie rod ends, Idler arm bracket, idler arm and pitman arm. I purchased everything from CARiD at about half the cost of the chain auto parts stores and about the same price as the part store "economy" parts. I read that the Moog problem solver parts were better and I certainly agree. With the original part, if the thin rubber boot that holds the grease fails (or if a careless lube guy blow out the boot by over-lubing) the joint loses lubrication and is exposed to dirt and other contaminates. When this happens, the joint WILL fail. However, Moog redesigned each part, eliminating the rubber boot of the original. With the Moog design, the grease is held inside the metal casing of the joint. There is no rubber boot to fail. In its design, Moog eliminated the weakest link in each suspension part, the rubber boot, and created a part that could actually live up to a life-time guarantee. Now, some people might not need this extra protection because they trade cars every few years. But if you are reading this, chances are that you are like me; trying to squeeze every mile out of your current vehicle. If so, get Moog's problem solvers, do the job once and don't worry about it again.

Fit my 2000 Ford Excursion
Drop in replacement for the OEM ball joint. These have the grease fitting. If you grease them at the same time you do the oil changes you should get good mileage out of them. (if this is the top ball joint the U-Joint will hit the fitting, however, you can take the plug out and still grease them and reinstall the plug) Moog was the other ball joint used. I don't remember which was the top and the bottom, but they are obvious once you get them.
