I guess I add to this discussion some more questions. Looking at replacing the ball joints in my 04 K2500. I have to confess, that early on, I messed up and over greased the ball joints on this truck. Pretty much all of them burst open. I had been used to greasing the front end until a little bit of grease comes out of the boots. But I was not expecting that the boots was actually burst. I have been good about greasing the ball joints at every oil change to make sure there is still some in there, though, recently, a couple of the grease zerks won't take grease unless I jack up the front end (relieve the load) on the ball joint first.
I am now looking for which ball joints to buy and this has me a little confused. It looks like MOOG has the Problem Solver type which even says to grease them to flush out any dirt / debris. The other brands (MEVOTECH / Delco / etc...) of ball joints look like the boots are NOT meant to relieve any grease out of them.
First question - how much grease are you supposed to use on ball joints? Are all ball joint boots supposed to allow the grease to escape?
My second question is which ball joints to purchase? Are any one of them better than the rest? I know you can purchase an upper arm for just a few bucks more than the ball joint by itself, but not sure which one to get. Looking at the price, I think the lower ball joint by itself will be quite a bit cheaper than purchasing the whole control arm assembly.
