The tank is currently emitting a horrid whine at anything above 30mph.... It's a high-pitched screeching - ie typical knackered diff / back axle noise. Doesn't matter what gear is engaged, including o/d, and it doesn't appear to be connected to the engine speed (as opposed to road speed) so am I right in assuming that it can't possibly be the gearbox / gearbox related? Until Friday eve, it was only noticable in the background & on the overrun / when decellerating / under engine braking. Now, it's there all the time above about 30mph. At the moment, I'm looking into buying a s/h diff or new CROWNwheel & pinion, but before I part with any cash, is there anything else that could be causing this noise??? Thanks

Could be a prop U/J or a wheel bearing though prop problems are usually accompanied by lots of vibration too.

howling or droning noise?
Above 30 ...
...with my Mini it was front wheel bearings. No play in bearing and sounded like a diff gone but was just a noisey bearing.

Would that still do the shrieking? The main culprit is the diff, as the ujs / propshaft support bearings were checked only a few weeks ago, & one was replaced due to a nasty vibration at high speed. There's also an intermittant vibration but I think that's an iffy gearbox mount rather than propshaft as it's not road or engine speed related, & also changing gear (from any to any) or dipping the clutch can clear it.
It's all very annoying.....

i assume youve checked the diff oil? diff used too whine like crazy on my old capri. old boy told me to shred a plastic carrier bag and stuff it in there. mad old curse word i thought, but i did it and hey presto no more noise!!(i put fresh oil in too )ran it for another 15000 miles with no probs ;D ;D bodger?me? never

Shouldn't be the oil as they were checked a few weeks ago, & there's no sign of leakage. The old bus has been round the clock a few times so it's not hugely surprising that this has happened, but it's the sudden increase in the noise that is really worrying me :-(

Could be a bearing carrier breaking up. My bearings in the sprint sung like an absolute curse word........when I changed it, couldn't belive it.
Jack it up, rock each wheel from side to side by grabbing it at the top and bottom and pushing/pulling it. If if feels like there's excessive motion then it's probably a knaffed bearing.
Also, on an off note - very difficult to tell where a noise is coming from in a car.

If its just suddenly happened could be a bearing collapsed/broken. Had that happen in my range rover just as I was pulling upto a junction and as it had a viscous coupling centre diff it locked all wheels up when it happened ;D.
As LewisK78 says jack it up and you should be able to identify where its coming from. Put it in gear then rotate one wheel at a time. This will isolate the prop and the pinion shaft. Take it out of gear rotate both wheels in the same direction and you can check for pinion or prop/uj noises.

I'd be checking diff oil, gearbox oil, prop bearings, rear wheel bearings and finally the diff itself if the oil didn't quieten it down. If the diff is still whining like a teenage girl after it's oiled up then it's probably shagged ;D

Thanks guys for all the advice, esp re diagnostics. Unfortunately I've nowhere to do this sort of work, so it's now booked in with a mechanic whose been working on Amazons for at least 20 years. If it's the diff, fingers crossed that the CROWN wheel & pinion are ok....

Might be something in the fnal drive that does not mean CROWNwheel or pinion replacement - like pinion shaft bearings. Or it could be a gearbox output shaft bearing. As has been said, propshaft or driveshaft UJs usually vibrate as they begin to fail. Does the noise come from the transmission area or from the rear? Hope you get it sorted for not too much wonga... My Omega broke down Friday night. Must be the season for it! I'm

Not 100% certain on this, but I don't think it's the gearbox as the noise is there irrelevant of which gear is engaged (including overdrive) - does that make sense to anyone else?
Not expecting it to be cheap, but whatever it is that needs fixing / replacing, I want it done properly as I'm not intending to sell this car! Best of luck with sorting out your Omega. I found out last night that after the new turbo the other month, my bro's Pug 306TD has just needed new driveshafts - £300 just for the parts (which he fitted himself).....
:-(

But from the noise you have said I wouldnt have thought it would be gearbox. That seems a bit extortionate for pug driveshafts. Why not just CV joints? or had the shafts themselves broken. I know some citroen/peugeots cant have the cv joints replaced but I didnt think that applied to 306`s.

it's almost certain to be the diff. I had a Westfield that only whined on the overrun and as you sit virtually on top of the back axle it was very easy to diagnose.

I've seen similar issues with very high mileage Volvos myself, I reckon your diff might be on the way out, they tend to get overly noisy when things get serious. It might be a good idea to try and find another diff for it, are you a member of Volvo Owners Club, they might be able to help you out with a spare one? I'm not entirely sure if later RWD Volvo axles and diffs are close enough to the Amazon ones to be an easy swap, but it might be worth checking, Volvo were very into interchangeable mechanical parts up until the 90s as you know, so if a 122 diff doesn't turn up you might be able to source a whole axle from a later model and switch it over, only thing is I suspect 2 series axles etc are a little wider but I might be wrong.

Amazons use different axles to later Volvos, and the estates have a unique casing, due to the different rear suspension. I'm hoping to hear back in the next few days from another Amazon specialist regarding the availability of a new* (or vgc used) CROWNwheel & pinion or a vgc used diff, as it looks like axle rebuild time.
*from Sweden or Holland. Aparently the diff (3 different types) & ratio in mine is the most common one, so it shouldn't be too much of a problem getting one. No idea yet about the cost though.....

See that's what I was thinking, I had a feeling that the OTT interchangeability Volvos went on to have didn't happen until later, and as you say the fact that it's an estate makes things more difficult, but at least you have a lead on getting the parts for a rebuild, best of luck with that and I hope the price isn't too much, being a Volvo I'd imagine it won't be too bad but then again I've never owned an Amazon, just the later, brick-shaped types. ;D
