I took my Durango in to a fast-lube place for an oil change (I usually do oil changes myself, but I'm a bit behind so wanted to get it done.) After the truck was on the lift for a few minutes, the tech comes into the waiting room with a piece of white paper with three greasy black smears on it. He explains that they are "samples" from the front and rear diff's and the transfer case and that I better have those drained and refilled as well @ $60 each.
I asked him to show me. (I just replaced these fluids 8,000 miles ago). He took me into the shop and I watched as he put his finger into the transfer case to get another "sample" while explaining that his shop does this check as a free "service"-- he wiped his finger in the dirt on the outside of the case on the way out, then made another black-oily streak on the paper.
Boy was he surprised when I put my own finger into each fill hole and made three clean streaks on the paper (bright red for the t-case of course). I enjoyed the embarassed look on his face.
He squirmed a little bit, but finished the oil change and I went on my way (yes, I checked that the oil and filter was in fact new and that all the plugs had been replaced.) I wish there was more I could do, but at least I can post here so others will watch out.
