Okay, I promise to never use that word again. But if you had one of those compressors, you might use the same term to describe it.
So, guess I can't help there. But on the other problem...
First time my 93 broke a motor mount, I thought the tranny was going. That one was on the passenger side right next to the water pump pulley. Toughest one to replace. Just recently the front one on the driver side broke... same "thud" when pulling away from a stop.
I had the wife put it in drive and give it some gas with the brakes on. In the case of the last one, it was easy to see the motor come up off the mount as it separated. That one was much easier to swap out.
