In my experience, most Asian vehicles take ATF in the power steering reservoir/system, not "power steering fluid" which tends to be for older American vehicles.1. I am running valvoline powersteering fluid
2. I am running H55 that I got from GLTHFJ60, and using an old trans mount that was in good shape.
3. Not sure on checking the trans mount with the help of a friend
4. Using the engine mounts from the donor truck, they were in good shape also. Not a lot of engine movement.
Maybe try flushing the system and refilling with ATF and let us know your results.
