They’re tiny, difficult to maintain without a grease fitting, and found in just about every vehicle out there–you guessed it, we’re talking about ball joints. More accurately, Dynatrac is talking about ball joints, with this special short video seen above.

The stock ball joint’s plastic degrades quickly in off-road usage.

Presenting cutaway stock Dana 60 versions with Dynatrac’s rebuildable versions, the narrator goes apples-to-apples to explain what makes factory ball joints so prone to wear and tear versus why the aftermarket variety can last for such a long time. The inner workings of the stock ball joints are made up of a metal ball pressed into a plastic material bearing socket, which enables “free” movement inside the housing.

As is often the case, the plastic material degrades over time from friction and pressure exerted on it, and eventually the plastic gets loose. This leads to all kinds of noises, from squeaking to popping, and makes for an unenjoyable driving experience.

The plug in a Dynatrac ball joint absorbs impact far better than the stock plastic ever could.

On the flipside, the Dynatrac ball joint features a spherical, heat-treated stainless steel bearing with a Teflon lining for enhanced lubrication. The grease fitting is nestled into the top of the ball joint’s housing, so it won’t run the risk of being torn or popped off from flying debris or random impact.

Reinforcing the part’s overall toughness is its chromoly stem and heat-treated spherical bearing. The plug, meanwhile, maintains a minuscule gap between the stem and housing, the better to allow movement and also absorb shocks so the spherical bearing can keep doing its job.

All this to say that there are great, valid reasons to choose Dynatrac products over just replacing stock parts with stock parts. To find out more, check out the provided information to get you in touch with the off-road experts at Dynatrac.
