For the ball joints, the clear sign to replace mine was the boots on them. Mine were torn open, shooting out all the grease I would fill them with onto the wheel well skirts, every time I hit a bump. No point in greasing ball joints if they are going to leak, right? If they arn't greased, they wear quicker, and ball joints are what hold your spindles to your control arms, and tires are mounted to your spindles....yo
u get the point.

A good way to check for wear is to jack the front of your car up, then rock the tire in and out with hands on the top and bottom of it. If there is excessive movement, then they will need to be replaced.
If you have torn boots, your spindles will be COVERED in grease, like piled on. I scraped off grease piles 1/2" thick off the driver's side, and yesterday I scraped off grease piles an ENTIRE INCH THICK off the passenger side. I didn't realize the spindles were soo narrow, as the grease build up made them look a lot bigger!
Now my front suspension is nice and clean, and should make it easy for the alignment shop to work on!

I haven't had an alignment done on the car since the engine rebuild due to the ball joints. Les Schwab wouldn't give the car back unless the ball joints were replaced due to leaking grease boots.
Good luck on the maiden voyage, and I hope you don't have any unexpected events happen along the way!
