Moog gusher bearing technology: A deeper look

The powdered-metal gusher bearing in Moog’s ball joints make them last far longer than OE ball joints.

Moog Gusher Bearing: Exactly What You’re Looking For.


Having to Replace Ball Joints all the Time?

Powdered-Metal Gusher Bearing. Maybe you’ve heard this term before, but what does it mean? It’s one of Moog’s innovations. Moog designs all of their products to target flaws in the OE design. One of the design flaws for most OE ball joints is their inability to flush out harmful road contaminants that lead to corrosion and premature wear. This problem leads to several steering problems that can include: shimmying in your vehicles front end, uneven tire wear, and looseness in your steering wheel. If you’ve been experiencing these problems and want to know how DST can help then look no farther because Moog has the solution.


OE Design Flaw

As previously mentioned, ball joints in most cars aren’t serviceable. The premature wear that this causes leads to several problems that can’t be pushed under the rug for very long. If left unchecked for a long time, a corroded OE ball joint will snap. Which will cause you to spend even more time and money on costly repairs? All of that just sounds horrible, doesn’t it? I agree with you, and I want you to avoid that as much as you do.


Moog’s Gusher Bearing

Moog is here to help you avoid this altogether. Moog’s gusher bearing technology disperses the grease evenly across the bearing to help resist the wear that caused your OE ball joint to corrode and fail. This gusher bearing technology also holds the grease between the ball and the bearing to provide greater strength and durability. The serviceable design also allows you to grease your ball joint and keep new lubricant flowing through the ball joint which will flush out the harmful road contaminants that lead to the OE ball joint’s premature wear.


Sealed Dust Boot and Warranty for peace of mind

Moog’s ball joints also come with a sealed boot that shuts out moisture and debris, as well as keeps, contaminants out of the socket assemblies. The powdered-metal gusher bearing in Moog’s ball joints make them last far longer than OE ball joints. The vast majority of Moog’s ball joints come with a lifetime warranty. So if you’re looking for an upgrade on your vehicle that is just strictly better than OE ball joints, Moog is exactly what you’re looking for. Moog also doesn’t discriminate, they offer ball joints for Ford, Chevy, and Dodge vehicles. If you need help figuring out if Moog makes a ball joint for your vehicle then all you have to do is simply contact DST’s customer service team at this link: DST Support.

      Hey, thanks for the story Calvin,

      Yeah that integral dust boot looks kind of funny at first but it has many advantages. Easier installation is a big plus, the encapsulated washer in the dust boot minimizes radial and axial movement, and the boot has more surface area contact with the stud and is more durable than the press-on variety.

      Here is a product bulletin from Moog going into more detail about Moog’s Ball Joints for compression-loaded suspensions.

      Here at DST we love the innovative designs that come from the mad scientists at Moog. Does anyone else have funny stories of dealing with Problem Solver parts at a garage or shop?

    How can these be greased routinely without a zerk

      Hey Sam,

      Most stock ball joints manufactured after the 1980’s are not designed with routine service in mind since the joint is sealed and shouldn’t need more grease. But if you do want to add some grease the easiest way is using a needle to bypass the dust boot. We offer a Grease-Gun-Combo which includes everything you need to get some grease into that ball joint.

      • Attach the zerk needle to the end of the grease gun
      • Stick the needle into the boot
      • Fill with grease
      • DO NOT OVERFILL, putting in too much grease can unseal or “pop” the boot giving you even more problems

      If you’re wanting to grease your ball joints regularly we suggest checking out Moog’s line of problem solver replacement Front Upper and Front Lower Ball Joints which are being constantly improved with features like the Integral Dust Boot or a zerk fitting and grease relief valve for easy maintenance.

      Hope this helps and good luck.

        The idea isn’t that they need more grease, it’s that you’re flushing out old grease with wear particles in it. You want to overfill to the point that most of the old grease is gone, oozes out, then pop the boot back in place.

          Hey, good point!

          If you’re putting new grease in then you want as much of the old stuff out as possible. But sometimes you do want to add grease just to add grease.

          Even the best dust boot can let a little grease escape under the right circumstances (the wear particles door swings both ways). If this happens enough then you might find yourself with a dry bearing that will wear that ball joint down.

          If the ball joint came with a zerk fitting installed then it was likely designed to be overfilled like you’re saying and in that case go nuts with the grease gun.

          But if you’ve installed a grease zerk on a sealed ball joint then be wary of putting too much pressure on the boot. That seal may not have been designed to have a lot of grease pushed into it.

          Thanks for the tip.
