hello group, trying to get the upper ball joints out of the control arms... got the special socket and with a breaker bar, I get the ball joint to back out until it seems to be hitting a lock ring on the other side. is there such a locking ring on these or do I keep trying to break it loose? this so called ring, which has little half circle patterns around it, seems to go all the way around the ball joint as it also rotates as I try to loosen the ball joint... as usual, all help greatly appreciated!
