OE Design Flaws

If you're hearing a clunking noise from the front of your Jeep JK or Grand Cherokee then you probably have a loose ball joint. Steering wander and a shimmy in the steering wheel can also be signs of a bad ball joint. Lower ball joints take a lot of punishment and will wear out eventually, but the original ball joints on these Jeeps come up short in a few areas and don't last as long as some other options. Some of these problems are with the design of the ball joint, but there are some external forces that can contribute to premature ball joint wear and failure. Here are some of the factors that can lead to premature ball joint wear:

  • Non-Greasable Design
  • Plastic Liner in the Stud
  • Vulnerable Dust Boot
  • Lift Kits
  • Bigger Tires
  • Off-Road Use

Moog's Solution for Ball Joint Failure

Moog Problem Solver Ball Joints are an OE replacement that basically takes the OE design, improves it, and adds some premium upgrades. This means that a stock Jeep JK running these ball joints will very likely outlast the OE parts, and will be covered by a Limited Lifetime Warranty. In fact, the techs at Moog have said that running a 2? lift and 35? tires should not be a problem for these ball joints, but their lifetime warranty is only valid for stock suspension setups. Here are some of the benefits of the Moog K3185 lower ball joint over the original:

  • Full ball hardened Metal Stud
  • Greaseable Design allows for grease maintenance
  • Integral Dust Boot sits lower and is less likely to be damaged
