Got about 105k miles on my '06 4.7L. Noticed some ATF on the transmission cooling lines a few months back when I changed out my sway bar bushings and end links. Took it into the dealer over the weekend and they confirmed the hoses were leaking - I was overdue for all the fluids anyway, so I bit the bullet and had them do the new lines, transmission flush, transfer case fluid, and front/rear diff oil change. During the inspection, they also found that one of my front differential bushings was actually gone and the other two were in poor shape. I had been noticing the clunk when put in Drive or Reverse. $1500 later all this is now fixed - can't complain - the Commander is still in great shape and drives nicely, and has been relatively trouble-free. Looking forward to another 100K miles!
