Why should one not use currently available cheap joints from the Far East?
The metallurgy of these joints is often very second rate. Thus they wear out quickly it is therefore a good idea to repair the new joints to give them the best change of lasting. I know of a set of Hyundai Starex ball joints which were replaced with new part that lasted all of 3 months after installation (Original equipment parts were too expensive)!Mostly replacement New joints have substandard plastic bushings thus becomes loose after a couple of months after installation.
