I found it a good practice to remove the skid and inspect my transmission and transfer case on a routine basis, it's also my opportunity to clean out the caked on mud and debris gathered from the "shovel". Just recently, I discovered my transmission mount was sheared/cracked on the rubber section. I did not notice anything wrong with the mount while driving, as I could neither feel or hear any telltale signs of a cracked tranny mount. It was a good thing I removed the skid, else I would not have notice the issue until it became a much more serious problem.
Just remember to use antiseize on the skid bolts and torque to 55 ft lbs
