2000 Grand Cherokee Limited, 116K, 4.0.
Recently changed speed sensor but other than that no major problems.  However it has started to make a clicking noise, similar to that if you put straws in the tires spokes on a bike.  The clicking increases as speed increases, but will not make the noise if in neutral, stopped and you simply rev the engine.  I am stumped to this.
Also A/C has been getting weaker and weaker.  When I charge it there is slight improvement for a minimal amount of time.  Today after driving for 5 hours I notices normal fluid on the ground after parking, but then noticed a piece of ice fell off.  NOT NORMAL.  Any help w/these problems would be great.  I have access to most tools and lifts at my Air Force base and would love to save the needed money.
