My gearbox is needing attention and I have a steering rack waiting to be fitted so I'm putting all the funny noises down to them at the moment! When these bits have been sorted I'll have a better idea if the funny noises still exist!

Just an update. I've booked the D3 in to be looked at on Feb 2nd. I'll be surprised if it's a bearing though.
 Thanks,

Just a little update. I've been trying to figure out the issue and I'm ruling out a bearing issue.

The noise sounds very much like gears or the likes winding up. (If you imagine the sound a vhs used to make when rewinding...that's pretty similar).

Now, the noise is only really noticeable when I have my foot on the throttle, weather that be heavy or as light as anything. It is very Audible when accelerating or sitting at any given speed with my foot on the throttle.

So, what do we think folks? Diff, transmission? Suggestions or answers welcomed!
 Thanks,

Adam

Modern wheel bearings can be a nightmare to diagnose
Take your car a drive till said noise is evident then make long sweeping steering inputs
If it's a bearing that's faulty it will be louder when loaded on that side then quiet when unloaded
Hope that makes sense
This is by no means a proven method but it does work
Or buy a stethoscope jack up and spin

After a longish drive, point a infra red temperature gun at the wheel/hubs and look at the temperature.
If there is a major difference, the one running hotter is usually the bad one.

It can't be a bearing. The noise is only apparent when in gear and under load/acceleration.
 Thanks,

hi I use north eastern 4x4 on ross road Portrack Stockton always gives good service he always gives you a price for the job I have used him for over 14 months now and I am very satisfied mine has to go in for a oil leak on front diff to remove this and reseal costs £280 including vat
hope this helps you

Thanks Waxman, appreciate that. I already had it booked in with Durham 4x4, which I had to put back anyway to the 11th after something came up.

I suspect it is not a bearing issue making this noise, although I have developed a slight squeak the last few days, but I think I'm due a disc/pad change which I'll do myself.
 Thanks,

Adam

Not my diff, it's my engine!

Hi all,

I noticed today that the whine is present when revving, even in neutral. So, this worries me a lot. It's booked in for Thursday, but I wonder if you all had any suggestions?
 Thanks,

Adam

Sorry, I've not read the whole thread but the Air Conditioning compressors on these tend to whine quite a bit. Does the whine persist when you turn the AC off?

Put the air con in economic mode or turn it off completely. AC compressor clutch are known to get noisy

I haven't tried this, but I'm going to after I've eaten! Thanks for the suggestion.
 Thanks,

Ok, just been out and done this, and unfortunately it's still very much present. Belts? Alternator?
 Thanks,

Could be. Looks like you're have to get a stethoscope or the old bar and ear hole trick. Or maybe just for a really short time remove the aux belt and run it. By short I mean no longer than a minute or two and preferably with a cold engine
