We used to get a noise like that from the trim at the bottom of the windscreen on our old L322 from wind at certain speeds, fixed by running a small amount of sealant along under the edge.

Kind of,doesent do it all the time though.

Hi there rangietragic,
When I bought my 2003 Rangie ten months ago, I test drove it mainly within city limits. When I drove it home after picking it up I had speed related noises over about 80kmh.
A Range Rover mechanic told me it was a front wheel bearing. He was a bit out of the way so I took it to a more local Range Rover mechanic and told him it was a wheel bearing. I picked it up, he told me the bearing was fine, that it was the tyres, and I should do a diagonal rotation so the wheels rotated the opposite way. I so didn't believe him!!
But, I did what he said. Problem solved. Noise gone.
The culprit......and apparently not at all unusual.......Goodyear Wranglers!!
Hope that helps.
Bob.

PS. AND...It didn't do it all the time. Depended on road surfaces and weather!! And sometimes louder than other times.

Thanks,havnt heard it for a couple of days now.Heers hoping!Further to my lack of power issue,changed fuel filter,no difference.Seems to only be when engine is cold.Wehave a bit of a hill about 400 mts from home,on reaching it at about 80or so,seems to have a flat spot, then takes off again.Tried it when engine was still a bit warm,no problem.Any one got any ideas?

I had my L322 windscreen replaced (well it was with the RWC)
and have the same problem, noise comes from the top middle I think,
taped the top of the screen to see if that was comming from there, but still buzzy. May be comming in under the top at the sides. Any ideas? The roof track trim does'nt seem to hold very well in the clips as it run down into the corners at the top of the windows.

Keep taping in sections? To find the problem? I Do'nt realy want to put sealent everywhere.

I drove over to Melbourne through last night, had a fair bit of wind noise on the wind screen but It was blowing a gale out so maybe its not too bad....

Some of the early delivery L322s (02-03) had issues with the sealant used on the windscreen. It didn't take in various places but the most common seem to have been the bottom of the screen.

I did the same thing with mine as bertness. Test drove it around the city but didn't get out into the open until later. Anything over about 80kmh with a slight cross wind and it sounded like a nest of angry hornets were about to come inside for revenge.

Checked around the screen and sure enough the bottom seal had started to lift. Spoke to the dealer, a quick run of Sikaflex along the seal and no more problem. That was three years back.

So, it's possible that your humming is caused in this manner. Remember there is actually a turbulent, high pressure concentration at the base of the windscreen so even a little bit loose will vibrate.

Hope that helps, and you isolate your humming soon (or at least teach it some lyrics )

Cheers,
Iain

Mine has been doing the same thing intermittently, so thanks to all for the thread - - I will go looking at the screen seal!!

Checked all the plastic trims in front? Lights? Grille? Once had a RRC grille that had a few broken supports- it "hummed"at around 80km then went away with increase speed. a little looseness can make strange noises.

I seem to hear a humming noise from my wife every time I mention buying something for RR! This relatively easy to diagnose and fix- new shoes, dine out, etc.
