I had the engine mount replacement not too long ago.
Like everyone says, passenger side is not difficult at all. Just undo top 2 nuts on both side, and raise the engine.
The difficulty comes on driver side. Raising the engine only won't clear the mount due to transfer case on the way. You need to drop front subframe. Not complete removal, just undo 6 bolts until it still has couple turns on thread.
Subframe won't DROP, it's still tied to control arms, so you need to muscle it down.

The most tedious part was.... aligning mount bolts to engine. Since engine was lifted, and subframe was loose, I had to try few times to align engine mount bolts to the engine so that I can tie top nuts.
