We had a small leak develop on our trip to Wyoming and Montana. Just a slow drip, we lost about 2 quarts over the 4 weeks and 7,000 miles. While parked in its shed it lost another quart in the following few weeks. I drained the fluid a couple of weeks ago and started the removal process this past weekend. Not a difficult job (had the help of my two sons, 18 & 22)...
