Okay...I will do my best to describe this. There is a drivetrain noise coming from the front half of the truck...it is a light roar....low whine type noise that happens when I am lightly accelerating/ holding speed. When I let off of the throttle, it stops and when I accelerate hard, it stops. it is the loudest around 45mph....It does not stop when I swerve so that tells me its not a wheel bearing. It sounds like it is coming from under the center front half of the vehicle. It isn't super loud but I assume it isnt supposed to be doing it....Can anyone help

 

Could be the transfer case..if you can download the factory manual. Better yet, bring it in for inspection.

 

What are the conditions? Are you operating the A/C in Auto mode?

 

Have it looked at. The front diff job alone is $2000 plus at the dealer. The front diff has 0.61 liters of lube in it. That is less than two soda cans... see https://landroverforums.com/forum/lr...pinions-55810/ . The transfer case is more expensive....

 

If it does turn out to be the front diff and you or know a shop who can replace the parts inside instead of a refit, contact "unseenone" on this forum or search for his posts on the subject....

 

I seem to have this exact same symptom. It only happens when accelerating. My noise gets louder under heavier load... Going uphill, for example. I just changed the transfer case fluid (and both diffs) with LR recommended fluids. Didn't see anything in the t-case fluid or anything else standing out. No other noises or problems, and it seems to drive fine, just the noise. Any solutions found on yours yet? I'm planning to get mine on a lift and listen to see if I can find the source.

 

For me it waste front hub bearing.

 

If you suspect it is the hub, raise the front wheels off the ground and see if you can wiggle the front wheels (side-to-side when you grab the top and bottom of the wheel by hand). There should be no play in the wheels. If there is play, the wheel hub is worn out.

 

Definitely have it diagnosed to find the problem. I can help with it's a transfer case, transmission or a diff.

I had a hub go out before, it was caused by the nut not being staked, and it worked loose. I subsequently replace both, and kept one for a spare.

 

Hello, (1 post/rant)
My 3 had a whiny noise when idle. My first thought was idler tensioner, belt, etc. Local mechanic of course fixed it. Same day battery light on?, car dead!!, alternator gone!!! I am too nervous to let the hub fix it? And he NEVER takes his car to the repair "guys". Nevertheless. I needed to vent. And I am not going to the stealership for parts, and want an alternator today. So chainstore is the icing on this crap cake of a holiday week.
