Design: Housing material for ball joint includes steel type and plastic type of ball socket. Steel type collocates with M to M ball stud and steel bearing, and uses grease nipple to lubricate continuously. On the other hand, plastic uses mirror polished ball stud and plastic bearing (lupital POM). It seals special compound grease when in production, and does not include grease nipple.

Reminder: Some competitors use low label steel or incorrect heat treatment. This can lower the price, but also lower parts use life by 30%.
