I just had the rear differential fluid changed on my Pilot EXL AWD with Sensing a couple days ago and was surprised at the cost.......over $300 at the Honda dealer. Now they did use BG products which are generally more expensive, and it was done at the dealer, but this still seemed quite steep. Has anybody here changed the rear differential fluid themselves? If so, is there anything to it? I'm not in love with changing my own oil and fluids, but I have done it in the past. I generally find the cleanup and disposal aspect to make the process more trouble than it is worth, but thats just me. For $300 per change, however, I think it would be worth my while. Thanks in advance your input!
