My Brother inlaw is having troubles with his truck. Lower control arm, the mounting hole that the ball goes into is worn badley. He as not been able to find new replacement, thinks their not available. Any ideas? Could he shim it? or is there someone who does these repairs? He lives out in the desert and he really use'es his stuff hard and the dirt roads are bad out there too. If you got any ideas we would appreciate them, thanks Tom.
