Ya, It seems straight forward enough in many cases - when you can use tools to help you. I'm concerned about the tight space and the challenges of having to break a bearing free in that tight space. Don't really want to get started and realize I'm going to have to jack up the motor or ruin the pully and clutch to get it off the shaft. tx.

I looked back through the thread and didn't see a mention of the AC clutch bearing. Did you mix that up with the Alternator bearing in PoorES's post? AC clutches are rarely replaced by mechanics, nowadays most shops replace the whole compressor as it's more cost effective and reliable for the customer. I could be wrong, but I think you'll have a hard time finding bearings for the AC clutch.

Hayk, you're correct, I did misread the post - sorry for the confusion. Now I think, I probably have a bigger problem. I had an a/c clutch problem on an Infinity in my past, that I was able to ignore since I had moved to the cool West Coast. A bearing or a compressor change is another matter, unfortunately - probably $1k+ touch. Thanks for your keen attention and feedback. Cheers!

No worries, not for nothing I noticed a similar issue when I did my serpentine belt, idler pulleys, and tension pulley to try to find the source of the whining noise on cold starts. I spun all the pulleys by hand and found the A/C compressor the only one with some free play. So I wonder if that's the same movement you noticed. I decided to leave it alone as it's a very big job as you mentioned and is not guaranteed to be the source of my issue. My next step is to run the engine without the belt to see if the noise is still there without any accessories running. If the noise goes away without the belt, I may take it to the dealer for a 2nd opinion.

Aisin makes OEM water pump, so, you’re getting same quality. If I did my math right, you have 74K on your OEM/Aisin replacement pump. My OEM went just over 200K, so I think your current pump should be good for at least another 50K. And my OEM pump was still good; I replaced it as preventive maintenance also. I would replace the coolant, belt, and check the bearings in all the pulleys for play and replace accordingly.
