OK Guys I need help,
I have a 1999 Navigator ( AWD) . It has a whining sound when the truck is in " Park or " Neutral " as soon as you put the truck in gear ( Reverse or forward ) the noise goes away. The noise increases with engine RPM's. The whining sounds like it is coming from underneath the truck. Please HELP ME!!!!!
I checked the transmission fluid and it looked and smelled fine. Any more thoughts? Power steering pump sounded good. After i drove the truck about 10 miles the noise stopped., but it will come back when truck is first started. ????????????????
