Deeza Chassis Parts new innovative patented design completely eliminates the problems of serviceable chassis parts infiltrating dirt, moisture and other contaminants into the internal cavity of the dust boot.

Currently, existing serviceable ball-and-socket type joint chassis parts release excess grease from the boot cavity through a grease relief hole on the dust boot or through an offset opening channel in the upper boot wall. In many current designs, the lower boot walls are not connected to the body of the part leaving even more room for contamination. While all these designs provide for grease relief, they all have the problem of allowing outside contaminants to enter into the cavity of the dust boot when the position of the ball stud changes. The more the ball stud leans away from the center, the larger the grease relief hole expands increasing the risk of contamination which can lead to premature wear and failure.

Deeza’s revolutionary design allows grease to release through a uniquely engineered component placed between the dust boot and the body.  This design feature results in complete protection from contamination, regardless of the location and movement of the ball stud.

New innovative patented design

Revolutionary design allows grease to release through a uniquely engineered component placed between the dust boot and the body. This design feature results in complete protection from contamination, regardless of the location and movement of the ball stud.

 
This unique development consists of a specially designed dust boot with skirt and two Polyacetal components that form the grease relief ports. The apertures on these grease ports are completely closed by the skirt of the dust boot providing an isolated internal cavity.
 
When additional grease is injected into the joint, the grease is forced through specified channels on the bearing. This action lubricates the ball stud. The excess grease pressure bends dust boot skirt providing one-way grease relief route.

During normal operation, your vehicle ball studs lean away from center. Competitor designs 1 and 2 experience expansion and contraction of the grease relief hole in the dust boot. In time, contaminants infiltrates into the internal cavity of the dust boot. This can cause damage to the spherical shape of the ball, which in turn leads to a condition where the ball and the bearing cannot mate compounding the problem. This situation can lead to unwanted noise, premature wear and eventual part failure.
