There is just one really good upgrade possible, by using different joints that will hold up to 50.000km without any problems. I drive them on both of my buggies - its perfect. Price: 320€ - and you never need to think again about that stuff. The stock joints ( doesn't matter which manufacturer) are not working, because of wrong installation position when placed in. These bearing are made to fit vertical, not horizontal. Gesendet von meinem SM-G920F mit Tapatalk
