I have an 85 F350 4X4, doing the ball joints.
I Bought Moog because they have had good quality, I installed the new joints but the lower spins when I try to torque it, It doesn't spin in the knuckle but the joint internally spins making it impossible to tighten. I replaced it with another and it does the same. I have done many ball joints and never had this happen on quality ball joints. Any suggestions? I have had this happen on an old worn-out joint and had to cut it out but never when installing ball joints.
