Banging noise in front end

Hey Gary, it's a long shot but I found these notes in my files from when I had my p30 my parts guy was pretty good and I have noted two different lower ball joints for the p chassis. Moog K6122 and K6175 the first has a narrower shaft the second is the correct one. I know your front end was pretty much rebuilt. Wonder if they used the narrower shaft one. When hitting a bump would possibly make noise and while braking puts pressure on it and goes away? IDK just thinking out loud. If you happen to have a receipt with parts and numbers used. Hope you can figure out your problem.

I know what you are saying Mike, I had that wrong lower ball joint installed on the drivers side and it failed on me two years ago in Ohio. I don't want to go into along story but the shop out there put the wrong one in also. Superior Spring found the bad ball joint and replaced it. When they replaced the lwr A arms the ball joint came with the arm. I borrowed a 12 ton jack and will jack it up by the lwr A arm to compress the coil spring when the rain stops and check the ball joints. I realized that just using the MH jacks was not really a good way to check the front end parts because of the tension on that coil spring.
