What does the law of buoyancy mean

the law of buoyancy is the principle that describes why some objects float over water and some others sink: when you put something in water, it receives an upword force equal to the weight of the water it displaces.
this is important in diving in many ways.. and in particular, in diving, you always want to have a neutral buoyancy: this means that if you are standing still in water and you have a neutral buyoancy, you don't sink nor come back to surface

you have a neutral buoyancy if you "displace" always the correct volume of water.. in other words, you always need to occupy about the same volume: if you go in deep water, the water pressure will "reduce" your volume, so to mantain a neutral buoyancy you have to inflate air in your buoyancy compensator jacket to expand its volume.
otherway, if you're coming back to surface, pressure reduces and your body occupies more volume, so you have to deflate your jacket.

Ball joint on hilux surf gen 3 popped out

Didn't it have a castellated nut and a cotter pin? If no cotter pin, maybe the nut worked itself back off, or wasn't tightened enough. Fit it back on to test fit: the ball stud should be smaller diameter at top and get larger towards bottom, so it pulls in tightly into the hole on the knuckle, which is also smaller diameter at its top end. Know what I am trying to say? As the ball joint stud goes into the knuckle, the more it goes in, the tighter it fits. When you get it in, it should be a very tight fit.
