[Megamole]

So I just finished changing out a bad water pump on my YJ with a flowkooler unit and the throw out bearing started making noise. I can tell it is the throw out bearing b/c it get quiet when I push in the clutch. It is making the sound like a bearing on it's last leg.

My question is can you replace a throw out bearing without doing any other transmission work?, is it expensive? I have a swapped in BA10, milage unknown and it has had pretty bad gear wine since I lifted the Jeep last year? Any suggestion would be great.
