Tried what you recommended and I GOT 10,000 MILES AGAIN!!!
Thanks for the help! Scott, thanks for the help too. I am sure that for other models the instructions in the manual works too.
You were right Dan, the 'alternative method' works!!
FYI, I've got around 66k on my '99 ML320 and she sure drives great! Had to change my set of tires though because it was kinda 'getting there'. Am using the Michelin LTX 4x4 now. It's a little bit of a harder ride than the original Grand Treks but if you're not so meticulous, you really wouldn't feel the difference. Good traction. Was advized that the LTX's are good in the snow too.
Hey thanks again Dan.
