Welcome to site :)

I think you need to describe the noise better...

Is it coming from diff area, or more from g/box, or from wheels?

it's not the gear box, it sounds as if it's coming from the back of the car.
sorry but it's hard to tell when you are driving it. around the wheel area.
my missus just japps!!!!!!!!!!

Check the brakes (both discs and handbrake drum), and also wheel bearing...

Any odd tyre wear? are you worn down to the wear markers?

Does the droning vary with road speed or revs? If road speed it may be the diff but, as said before, could be rear wheels.

a fairly reliable indicator of A (single) worn rear wheel bearing is if the noise reduces, or even vanishes altogether if you turn a corner (usually at a reasonable speed) ...it'll only be one way... either left, OR right....   that makes it any better....

this is as the weight transfers away form the corner with the worn bearing....   so if your rear left (nearside)  wheel bearing is going, it'll get quieter, or vanish when you turn left, and if it's the drivers side it'll get quieter or vanish when you turn right....


turning at a crawl won't do this as there's little or no weight transfer....  a typical good spot to try it is at a decent sized roundabout, or a motorway slip road....  the sort that goes on for a while....  then you can experiment to be sure....

If it's the differential, then usually (but un-helpfully, not always) it gets slightly worse in cornering...   also... looking at the diff, you might be able to spot a fluid leak.....  if it's run dry it'll be rapidly increasingly unhappy then fail altogether...  if it's not been too badly mistreated and it's caught fairly quickly, then sometimes a renewal of the Gaskets and seals and new fluid can revive them enough for another 50,000 miles ;)

A rear wheel bearing replacement  in a typical Garage witha labour rate in the region of £50-60 per hour would cost about £200-£240 inc the bearing...  

Apparently.... according to Gurney's , one of our Vx places around here...     Vauxhall have brought out a special tool for aligning them... which they advise use of , otherwise they can fail early....  (like a week after fitting)

however any garage with a decent relationship with their local Vx supplier/dealer should be able to borrow it to do the job... but usually, as and when it suits the supplying Vx dealer's schedule, not yours or your local garage....  

(that's what ours did anyway... I had a new nearside bearing fitted last week)

although some tight arsed places may charge extra for this.,..



Rear diff replacements are definitely a "Get it from a  scrappy" job as Vx will charge a fortune for a new one...
