I just reviewed our conversations. Based on what you have described, I don't think it has anything to do with the rear. If you turn the AC on and the noise is coming from the front, it sounds like the AC compressor has a bad bearing. The bearing can be replaced, but by the time you add the part, and the additional labor to repair it, you are better off replacing the compressor.
Do me a favor. Aftermarket compressors can be found for under 300.00 dollars. If they try to charge you a lot more for the part, let me know and I'll direct you where to check for one. In addition to the compressor, they will need to recharge the system after it is replaced. I would expect about 1.5 hours labor + freon to recharge the system.
Please let me know if you have other questions or if you have questions about prices.
