1998 Pathfinder SE, 100k miles.
My brother was driving yesterday in some snowy conditions. He was using his 4WD and was doing city driving (ie stop lights and what not). He said that sometimes when he stopped the transfer case and or transmission would "slip" and he basically sat there and the engine would rev and not go anywhere. To quickly fix the problem he shifted the transmission (not transfer case) into neutral and then back into drive. Sometimes there was some grinding, but this procedure seemed to work. He said it only happened a few times. Any ideas what would cause this?
Also, another question. He just bought the Truck and it has 100,000 miles on it. I went to change the timing belt the other day and noticed that there was a metal Nissan sticker on the fan shroud that said Timing Belt replaced, and had a milage of 78k and a date of around a year or 2 ago (cant specifically remember). Should I not worry about replacing the timing belt?
