Imaginary noise/ whine

[Disco Muppet]

Afternoon folks.
Just got back from a mad dash to sydney, and I'm certain that I'm going insane.
Stopped to have a look at the Glow Worm tunnel and decided some of the mud puddles looked much more fun :D
Afterwards, both my passenger and I noticed a seemingly sporadic whine, noticeable only when you were next to something to "reflect" the sound.
Pulled up and checked all the discs to signs of something caught in them, checked the prop shafts, couldn't see anything wrong.
Thought it might have been the birds until it returned a while later.
It's entirely random, can happen off idle, under acceleration, rolling to a stop with no brakes, etc.
Only seems to happen when the vehicle is warm, doesn't sound like pulley noise (Believe me, I'm familiar :p )
Also seems to a be a bit of a growl and a buzz in the steering cornering under brakes, most noticeable coming down the mountain.
Any hints would be thoroughly appreciated, as the stop and start nature has me baffled and thinking I might just need a good sleep.
First thing I'll do is clean it thoroughly, I find this often helps eliminate lots of the odd noises you pick up after dirty work.
Cheers
Muppet

..........and I'm certain that I'm going insane........

You put that in there just so that I'd comment didn't you Muppet?! Well you're bound to be a bit insane when your mother's a.....nah. Enough of that one.:p

Anyway. Grumbling wheel bearing perhaps? If you've been playing in muddy water, it might be worth checking.

No, now go away or I shall taunt you a second time!

I had considered this.
How would water get in?

Yes, I watched it yesterday, so be warned!

No idea how it gets in, but I know I've read more than one story on here of it happening. Same with diffs.

[Disco Muppet]

Hmm...
I do have a weep from the front diff breather in the axle housing...
Other than that the gaiters/boots are fine.

And bring it, I'm stocked up on French insults!

[Lyonbyrd]

mine started to whine & needed a new transfer case.. but i'm sure yours is whining for another reason :)

[Disco Muppet]

I seem to remember OffTrack mentioning growling on corners being indicative of TC failure on the horizon :(
It's definitely a 'rotational' type noise, at one point it sounded like someone holding a nail against the rotors.

You must be getting confused with the D1 forum. I'm sure every d1 comes with a membership of the Bearing Packers and Greasers Union judging by the frequency you see D1 owners recommending bearing repacks.

Hmmm looks like it might rain. Best repack the wheel bearings...

[Yorkie]

get the hose out and give all the wheel/brakes a good clean, then go for a drive and see if it still there. :)

Hey, at least they CAN repack them, unlike us high and mighty D2 owners who need a new hub :p

Hmmm, could be :blush:

It's not as if hub replacement is one of the common faults on a D2. You see more head replacements than people changing hubs. :)

That in itself isn't exactly something to boast about :lol2:

could be a stone in the disc/ between the backing plate. Splashed in from your mud puddling antics :D

I had something similar---noticeable after awhile when cornering it was the righthand front bearings:new hub all fixed:D

[Disco Muppet]

Hmm...
Seems to be more noticeable just off idle or idling through corners (i.e maccas drive through)
That could just be that I had the window open, stereo down and the walls reflected the sound.

[Disco Muppet]

Checked all the hubs this afternoon, zero play at all in any of them. Hoping it's not the hub as there expensive, ABS or not. Might have a closer look at the prop shafts.

dont forget , after you wash it you need to repack the wheel bearings.

Get a D1 owner to do it for you.

I remember the first time we got a reflected whine when passing a cutting or barricade, it sounded a bit like a belt squeal. Finished up being a broken bolt on the exhaust manifold.

That was something I had thought of but wasn't too sure the symptoms fit.
That might make good sense as it's quite noticeable on acceleration from a standing start.
Assuming that it is a broken bolt, that means it needs to come out which means expensive workshop time :censored:
Do I need to do the whole de-web and enlarged bolt holes, as it's not chipped and not likely to be as my insurance premium is going to be high enough for the next 6 years :wallbash:

[greg smith]

If it is the exaust manifold bolts the manifold will probably warped The best bet would be to do the exchange and replace all the studs--I bought the studs from England and bought nuts to suit--handed that to the LR mechanic---then picked the car up later!!!! the previous time it happened I was told that they replaced the broken studs and all is fixed--6 months later--same again!! So get to know your LR mechanic and talk him through what you need and expect:D

[Disco Muppet]

Checked the manifold today, all looks okay. No sign of soot anywhere.
Also had a closer look at the hubs, they look brand spankers.
Although the staked nuts are hardly what I'd call staked. Mildly dented perhaps.
