ac compressor noise!!!
 

Ok so I have a 2007 Aspen 5.7 and the ac is working fine but I started to notice that the compressor is starting to make a annoying rattling sound. I was told to get ready to replace my compressor and other ac related items as well. My question is do I need to replace other items like the dryer and expansion valves if it looks like just my compressor is going out. Couldn't I just swap out the compressor and pull a vacuum and recharge the system???? Let me know what you guys think...

In my experience, replacing the other items (dryer, expansion valve, condenser) is only needed when a leak has occurred in the system. When this happens, it allows outside air to enter in to the system. This air contains moisture which contaminates everything. So if you replace the compressor, vacuum it down properly before adding freon, then I don't see a need for replacing everything else.

That's what I figured... A compressor kit runs me $300 for a new compressor, dryer, orings , 2 expansion valves and some flush... Not bad for the price because just the compressor is selling at $200 alone. How involved is this and does anyone have a diagram on how to do this? It has rear control ac as well.

$300 for the whole kit including compressor, dryer, o-rings and expansion valves is not bad. Now I'm sure that does not include labor. I've done it once on my Ranger. Was a big headache. Changing out the compressor isn't that bad, but you have to evacuate the system first and you are suppose to recycle the freon which requires a special machine. Luckily mine had a leak so it was all gone anyway and I didn't have to do that. Some of the fittings require special tools. The Ranger had an Orifice tube (similar to the expansion valve) and it was a pain to find and replace. Then theirs the vacuum down after everything is installed. This requires a special vacuum. This can be rented, but you have to find a parts store that has one. Not to mention needing the proper line hoses to connect the vacuum and to add the new freon. In all, it's not as difficult as doing an engine overhaul, but more difficult than an oil change. The rear A/C controls doesn't matter. It feeds from the main line. Just uses vent doors to control the air flow.
