Well I'm far from being any kind of suspension expert and only know what I've experienced on my machine. Based on that, whether it's the stockers or aftermarkets, too much preload on the P5 just causes problems in general.
Yeah that’ll probably do it. Hopefully it is as simple as pulling the bolt enough to get some thread lock on it and making it tight.
If the paint isn’t cracked anywhere there and welds look solid I’d be willing to bet that bracket was tweaked in from tightening the A arm down at the factory. Just a guess from this particular pic though. You can make a better judgement call being able to see all the way around both sides of both A arm mounts I’m sure.
The P1 & P7 has a grooved steering shaft coming out of the steering box, the bottom universal pinch bolt needs to be in that groove, you may have to loosen top universal pinch bolt to get the bottom pinch bolt to rest in the shaft groove. Throw the bolt away and get a new one. This was a recall on some of the early P1's. Anyways match bottom pinch bolt of the universal to the steering box shaft groove then tighten top universal pinch bolt on to the shaft coming from your steering wheel. I would think the P5 would be the same as other P's. Now on to the ball joint, did you check it with the tire on? You won't be able to get enough leverage with the tire off to check unless it just falls out. Please keep us apprised.
Hopefully that and the steering knuckle are the issues. I'll bet there is a You Tube Vid of the process, You will probably need access to a ball joint removal tool ( $25.00 OR LESS AT HARBOR FREIGHT) and a press to install new ball joint.
