It seems like my truck is on it's last few hundred miles before I have to rebuild the thing...Just want to be prepared for that day, or see if I can do something about it now.
I'm getting some really bad sounding rattles these days.

 

I'd post on BC4x4, you might have better luck. The 22RE is such an easy engine to work on that I'm sure just about anyone could easily rebuild it for you.
