CARQUEST Greaseable Design

• Greaseable design works with the patented domed cover plate design
  and premium boot to keep contamination away from the socket assembly.
   
• Porous powdered-metal bearings hold grease between the ball and
  the bearing.
   
• Grease grooves in the ball or bearing (depending on application) allow grease flow to critical areas to ensure lubricated movement and to keep contaminants and wear to a minimum.
   
• The flow of fresh grease is directed across the bearing surfaces, displacing any accumulated debris away from the ball and bearing assembly.
   
• The grease-relief valve in the boot shuts out moisture and debris, while ensuring proper fill levels by releasing excess grease away from vital brake components.
   

	The combination of powdered-metal gusher bearing, grease grooves on the full-ball stud and grease-relief valve on the boot allows the proper amount of clean grease to fully lubricate the components (left).
