I just started hearing a 'whining' engine noise right at 1200 rpm. The engine needs to be warm to hear this noise. I hear the same noise whether in drive or neutral. Idle is at 700-800 rpm. There is no noise at idle. No noise at 1300 rpm+. I even tried shifting the transfer box into neutral - same noise. Anyone have any ideas?   Ron Brown (Ron) Member Username: Ron Post Number: 69 Registered: 04-2001 Posted on Thursday, February 20, 2003 - 03:52 pm:    Fan clutch? Belt squeal? Bearing in one of the ancilaries or more likely an idler pulley? Listen close to each bit and it will present itself.

Its a 2001 with 83,000 miles. I'll let you know If I figure anything out.   Kent Westbrook (Kentwest) New Member Username: Kentwest Post Number: 7 Registered: 10-2002 Posted on Saturday, February 22, 2003 - 11:20 pm:    I think Ron's right, probably the idler pulley. I've had this a couple of times around the rpm levels you mention.   phil (Powerslide) New Member Username: Powerslide Post Number: 37 Registered: 11-2002 Posted on Sunday, February 23, 2003 - 12:56 am:    If it is the idler pulley bearing or others, you should be able to pinpoint by opening the hood and reving the motor up and down*. Dealer (under warranty) just replaced both pulleys on my '00 DII at 47K miles *thru the T/B cable and I had to show the LR service advisor and he agreed it needed replacement.   OLIVER CLOTHSOFF (Everythingleaks) Senior Member Username: Everythingleaks Post Number: 236 Registered: 10-2002 Posted on Monday, February 24, 2003 - 08:04 pm:    The RH idler pulley fails quite often and creates the noise. LR just issued a new METAL pulley. The part number is PQR500060. I was going to list this in a seperate post but i saw you asking.
