Front Lower Ball Joint Problems in your Truck or SUV and a Solid Replacement

Your ball joint’s job is to connect your wheel to your vehicle’s suspension system. As you can imagine, heavy-duty vehicles can be taxing on your joints as they have more weight to support. Whether you are using your truck to haul stuff for work, or your SUV to take the kids to school, you need to have some pretty strong joints. There are some OE ball joints out there that are known to fail prematurely, because of a couple of defects that they were manufactured with, like it being non-greaseable or having a polymer bearing, etc. These are a couple of those vehicles:

Reasons for Ball Joint Failure

After years of hauling wood in your F-150 or taking all of the kids to soccer practice in your Expedition, you’re going to acquire a lot of miles. We know that these vehicles stay with you and your family for a while, and carrying a lot of weight during that time can put more than normal stress on your ball joints. Excessive use of your vehicle without regular maintenance checks can lead to failure in these OE ball joints.

Some of the trucks and SUVs listed above have ball joints that are known to fail because of issues with how they were designed, like a non-hardened stud, an inferior dust boot, and a couple of other problems that will wear down your ball joints and cause failure.

Internal Design Flaws

  • Non-Hardened Stud – Some of these OE ball joints feature a stud that isn’t hardened or heat treated. The heat treating process makes the stud stronger, and is recommended for durability.
  • Inferior Dust Boot – Your usual OE ball joint is going to feature a dust boot that sits high up on the stud, and provides basic protection, but your dust boot can be ripped or torn from too much pressure. If it tears, you will leak grease, causing your joint to dry out, and dirt and debris can enter and wear it down.
  • Non-Serviceable – The OE ball joint is also non-greasable, which means that you aren’t able to flush out contaminants, or keep the joint lubricated. Debris build-up leads to corrosion, which will cause failure.
  • Polymer Bearing – The polymer bearing on your usual OE ball joint is very unreliable, because of the material that it is made out of. When dirt and debris invade your joint, they pile up and cause the bearing to grind down. Once this bearing is worn, your joint is toast.

  • Hardened Ball Stud – One of Moog’s features is that the ball stud has been heat-treated, which is the process that hardens the stud and makes it more durable. Heat treating also makes the stud harder on the outside, and more flexible on the inside, so that when you’re hauling a trailer and someone cuts you off, or you’re taking the kids home and you have to swerve to avoid hitting Bambi, your joint would only bend a bit, instead of breaking off like an OE joint might.
  • Integral Dust Boot – The Moog ball joint has an integral dust boot that sits inside of the joint, so that there is no gap between the boot and your joint. It also features a double fold to ensure the tightest seal, blocking any contaminants from making their way inside.
  • Greaseable – Moog’s design features a zerk fitting, to allow the joint to be greased, and to let out the old grease and dirt. This will extend the life of your ball joints, by making sure that they can be regularly serviced.
  • Servicability – This ball joint includes a zerk fitting, So that the joint is able to be flushed out and greased. This reduces the amount of wear done on the joint and increases its longevity.
  • Metal Gusher Bearing – Another feature of Moog’s problem solver ball joints is the powdered-metal gusher bearing, which replaces that old polymer socket. This bearing is porous, so that grease may flow freely through the joint and maintain its lubrication. Unlike the polymer bearing, it is durable and with the greaseable feature, will ensure that you are getting the most out of your joint.
  • Forged Knurled Housing – The knurling (the textured pattern on the outside of the housing) allows the arm to grip the ball joint. This ensures that you will have the tightest fit, where your ball joint meets the control arm.
