SOLUTION: PROBLEM: BULLETIN: 27013–R • Greaseable design works with the MOOG sealed 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 ball stud 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 sealed boot shuts out moisture and debris, while ensuring proper fill levels by releasing excess grease away from vital brake components MOOG ® Greaseable Design Premature Failure/Excessive Play/Joint Separation • Non-serviceable socket design is unable to flush away contamination entering into the socket assembly. • Contamination remains in the assembly, causing corrosion and accelerated wear.
