Thank you in advance to anyone that may be able to help me out with either or both of these problems.
1. There is a grinding noise at all times during idle and cruising that gets even worse when the A/C switches on or off. I think it gets louder when the A/C shuts off. No problems with the cooling function. No other power losses or anything. Will be pulling the belts off one by one this weekend, but how do I examine the compressor clutch and what do I look for to see if that is bad or if the whole compressor is bad (assuming it is the compressor)? Any help on this would be much appreciated.

2. My steering wheel shakes a little at highway speeds over 60mph, shakes moderately under light braking and is smooth under heavy braking. I recently replaced the front rotors and pads thinking that would fix the problem, but no it did not. I did not look at the drums, but noticed that if I try braking with my parking brake only that it is pretty rough, but I don't really feel anything in the steering wheel. Could the drums affect the front braking system while braking with the foot and thus transfer to the steering wheel? Is the shaking from something else? Thanks again.
Regards,
Steve

1. Use a mechanic's stethoscope to isolate the grinding noise.

2. Possibilities include tires need balancing, aggressive tread design (Metric), and disk brake lateral runout.

When you worked on your brakes, did you clean and regrease the caliper pins with silicone grease?

OK, I already took it to a gas station mechanic and a honda dealership. The dealership said that the noise is loudest from the compressor, that is why I assumed, for now, that it is something to do with the compressor.
2. I did not mess with the caliper. The pins you mentioned are sealed in a rubber boot, right? I'm not sure what to grease. Thanks for the quick reply!

Yes, the caliper pins are protected from the elements by EPDM rubber boots. Carefully remove boots from their grooves, clean, and lubricate with silicone grease, which is what Honda recommends. Replace boots, if they are in bad shape. There are two pins per caliper. I use Motorcraft Silicone Brake Caliper Grease and Dielectric Compound (XG-3-A), which is available at your local Ford or Lincoln/Mercury Dealer. This is an often overlooked step that can cause the calipers to no longer "float." It can result in binding, wheel shake, and create a serious safety problem. Torque caliper pins to 20 ft.-lbs.
