Default A/C Compressor - violent rumbling and shaking

Hey guys, searched for this didn't find anything new, specific and relative.

2002 SC430, 150k miles, live in Florida.

Driving home from work on Monday, and started feeling a bunch of rough vibrating, somewhat violent. Sounded and felt like a blown tire. Pulled over to take a look, nothing was wrong (and I had actually just filled up my tires).

When I turned the car back on, I turned off the a/c. Sure enough, no issue. So I think it's the bearing in the a/c compressor or a/c compressor clutch. Does anyone have any experience with this?

Indy bearing replacement & cost?

Thanks all!

Can you check to see if there is a bolt loose? Maybe it will be obvious.. Also might lubricate the belts that could be causing friction. If you take some pics we could probably be able to better help you

I have the same issue when the temp hits 94. I'm also in FL.
So for the past few weeks I haven't had the issue

Ok, I'll take some pics when I get back home (in Russia).

Thanks for the insight, I'll also look for the obvious loose bolts and see about lubricating the belt.
