Title: Can someone help with diagnosis
Post by: STEMO on 25 August 2019, 09:37:58
Wifey's astra, 1.6 devil juice auto, three years old, 21000 miles, has a 'drone' which starts at around 25mph ans gets louder and slightly higher pitched as speed increases. It is more noticeable when first driving off and becomes slightly less noisy after 10 miles or so. It is constant throughout the gears and the auto box changes smoothly. This morning I noticed that it increases slightly when going around a roundabout and decreases for the two or three seconds when you turn left to come off the roundabout.
I'm thinking wheel bearing. Agree? Disagree? TIA.

Front or rear?

If rear, it could also be an indication of a binding caliper (handbrake mechanism) which eventually cooks the wheel bearing...

But yes, does sound like a wheel bearing  :y

wheel bearing possibly
thing about wheel bearings is they can pass an MOT ,you can't feel any play,no noticeable noise when rotating by hand BUT make an annoying "drone"
but worth checking the wheel bolts are tight PDQ

can also be a sticking brake pad or caliper
as it is low miles and probably not had any form of brake service yet ,that may be more likely than a wheel bearing  :-\
 or CV joint can also drone but at such low miles and age ,unlikely
also loose trim or road debris trapped can vibrate /resonate

Thank you all. Just been to Argos to pick up a new microwave (old one works fine, but we've had it so long it's gone rusty inside  ;D) and had a chance to act like a hooligan in a near-empty car park. I reckon it's a wheel bearing.
Now...will Vx see that as a warranty item?  :-\ Doubt it.
Title: Re: Can someone help with diagnosis
Post by: dave the builder on 25 August 2019, 10:39:05
has it had an MOT yet ?
they check wheel bearings and brakes for basic function
if it's a wheel bearing ,you could say it should last longer and should be covered by warranty
the  55 plate I MOTed friday has 86k and has all it's original wheel bearings , as does Mrs Builders 54 plate petrol 112k (astra H estates but the moving bits are the same)
but then I insist they don't ram it up the curb every day when parking  ;D

there is a TIS bulletin about the output shafts /inner CV joints which needed LUBE  :P on assembly and did not get it and is a known issue , the wear /lash is not fixable and requires new output shafts and CVs  £££££  :'(

They did my Vectra C one under warranty, took some convincing that there was an issue as by the time it got to a ramp, it was cold enough for the wheel to spin freely ::)

Got a new rear hub and two rear callipers under warranty. Network Q car used as a taxi... So there's hope :y

We bounce our cars on to the kerb every time we park...no alternative. Having said that, my 5 year old 55000 mile astra, which is back and forth all day, has no problems with wheel bearings.

Al: After me thinking I was going to have to fight them over the auto box, a wheel bearing seems almost trivial.

Seems low mileage for wheel bearing :-\

My father had a mysterious drone in his last Vauxhall. Turned out to be the (rear) tyres.

If they are going to need replacing in the near future then wait and see whether that makes a difference. If the rear tyres are original and have lots of tread then get them swapped to the front and see if that makes a difference.

Stupid question time...

Have you checked the tyres for even wear? My first 9-5 had exactly the problem you describe, but at 12yo and 90k, I thought wheel bearing was more likely. Turned out that a new pair of boots sorted it out - and they weren't even that worn.

Just a thought... :y

I could try, Jimmy, but I'm loathe to bin a couple of perfectly good tyres just to prove a point.

Surely money would be better spent doing some actual diagnosis rather than guessing
or are all 4 tyres shagged anyway  :-\
when is the MOT due ?
if the tyres have good tread and even wear, a brake service could include troubleshooting the actual issue and rotate the tyres at the same time ,and saves part swapping, which can prove expensive
I strip and service brakes yearly at least . they do get crudded up with rust and friction material
even IF the pads have plenty of material and the discs are fine, a clean up and lube improves brakes
better brakes has to be a good thing

it's your car, so up to you , just trying to give helpful advice based on years of spannering and being a tight arse  ;D

The Vectra one went at about 22k... The callipers sticking was a known issue which is ultimately what had killed the hub as all the grease had cooked off.

The engine soundproofing is pretty good on these tractors sitting in the cab
so, notwithstanding the annoying drone noise from passenger seat when occupied, it's probably transmission, brake ,hub related  :y

The 2.0 CDTi in mummy bus is damn near silent at 80mph cruise, bit rough in town but Iím happy with it.

Normally a wheel bearing would be more noticeable/change based on direction, was it worse or better on roundabouts.

Tyres are the most likely suspects,run your hand over the tread on the inside of the rear tyres and if it feels lumpy or scalloped then that's what it'll be,I've argued with many customers who have insisted its wheel bearings,if in doubt jach it up and spin the rear wheels,if the bearings are suss you'll hear/feel the noise/vibration

I know, Al, but when the old tyres came off, they were ready for changing. Three different makes on it, two originals on the rear and two different on the front. Considering we bought it at 10,000 miles, someone must have given them a hard time.

Anyhow......been up to my local garage, the owner took it for a five minute drive, and told me it's front nearside bearing. Going in Thursday. It probably should be a warranty job but, due to time constraints and a massive dose of CBA, I'll pay them to do it.

CBA or not, you really should throw it into VX. Warranty work is about the only feedback the factory gets for parts failures...

Also, might be more to it...

I know its been a while since I posted on here, but it was diagnosed to be the drive shaft bearing within the gearbox. With me also experiencing occasional problems getting into 2nd gear, even with no warranty on the vehicle, Vauxhall made me up a brand new gearbox and had it delivered and fitted all absolutely free. Top marks for Vauxhall!!

Northern or not, if the 'box suddenly fails, you'll be paying for that whereas if it were previously in fo related warranty work, then it would be covered by the original warranty.

225/45/17's, no good for a tadpole small frog.  ;D
Same size as on my Vectra 1.8. They gave me an awfully bumpy ride. I have today swopped them for 225/55R16s on Omega wheels, and the car is noticeably quieter and more comfortable.
All my Astras are on 205/55R16s, they are comfortable enough. I see in the Astra brochure the 17" wheels are available as an option in the Sport pack, which is standard on the 2.0 16v Turbo/1.9CDTi 16v (150PS) models.
My sporting days are over, now I seek comfort and quiet.

The wheel geometry is wrong. Ideally you need to source the Vectra C 16" wheels and tyres... https://www.ebay.co.uk/itm/VAUXHALL-ZAFIRA-B-VECTRA-C-16-INCH-STEEL-WHEEL-2160131-2-5-MM-TREAD-215-55R16-/333324552314 for example...

This was discussed before, and I never understood in what way the geometry was wrong. I was advised the Omega steel spare wheels would be all right. I reckonned other Omega wheels should be OK, as long as nothing fouled anywhere. Is it the offset? It drives all right, steering seems unchanged.

Get the offset in particular wrong, and you'll feel the issues when creeping out of a parking space. Although lots of people get away with badly specified wheels, advising someone to just try them is stupid. Using unsuitable wheels/tyres just because you've got a stash of them is equally bad. Such stashes of tyres tend to be well past their best if not actually dangerous as well.


J is the bead profile and has nothing to do with the width, although they're usually quoted together.

It doesn't mention how to measure the bearing clearances either, because it's utterly unnecessary information for most users. Ever met someone who doesn't know if their car is FWD or RWD or what it means? They're most of the drivers out there.


Tightening torque is a function of the M12x1.5 bolts, not the wheels.

Offset, wheel width and tyre size ;)

195/65 R15  ET35 steel wheels (omega spares) is the tyre/wheel size I said would fit on another thread

It's also the standard size for Astra H base models

as for offset ,it's measured in MM so look at a list of wheel and tyre sizes for vectra ,omega  ,astra

https://www.wheel-size.com/size/opel/vectra/2008/ (https://www.wheel-size.com/size/opel/vectra/2008/)


I ran Wolfrace 7J ET35 with 195/65 R15 (Vectra spec wheels/tyres) on my carlton for 2 years ,no handling or tyre wear issues

I did also say on whatever other thread it was, that Terry should check what wheels he had , not just "fit what you like"
tyre size , age and condition should be checked I agree

In my Vectra manual page 204 is about automatic level control, and has no box in the middle column. Manuals must differ I suppose.

It's the first page after Brakes, possibly 8 pages further on from Level Control :y (August 2005)

Semantics over page numbers won't change my, or the printed, point...

I was persuaded of the possiility of fitting Omega wheels on this Vectra by Nick's excellent lesson and other comments in this recent thread. http://www.omegaowners.com/forum/index.php?topic=145530.0. I do not wish to do anything unsafe, risky or illegal. I was considering buying Vectra C wheels to improve the ride of this Vectra. I have 2 sets of wheels removed from Omegas I have scrapped in the last two years.
I thank you all for your concern and advice.

Got it, p. 211. 'Warning. Use of unsuitable tyres or wheels may lead to accidents and make the vehicle unroadworthy'
Who would argue with that?

Terry had 225 wide tyres fitted anyway from his post above
the offset difference is tiny
rolling radius is within the scope of the 9mm tyre wear possibility

calculator here clicky  (https://www.willtheyfit.com/index.php?width=225&aspect=45&diameter=17&wheelwidth=6.5&offset=35&width2=225&aspect2=55&wheel_size=16&wheel_width=6-5&offset2=33)

Terry get the actual offset that is stamped on the wheels and width of wheel 7J  :-\  :y

I doubt Terry will be pushing the car hard enough for any geometry issues on a 11 year old car ,pottering about  ::)
Cast on the inside of the wheel spokes is the following data:
Omega 16" wheel:
7JX16H2
ET32
STTTK1 (all Tbars joined)
GM many times

Vectra 17" wheel:
7JX17H2 ET41
1411
Si7
13183227
Made in Poland
GM

So the difference between the two meaning that the Omega wheel will sit 9mm further out from the center of the car. What that does to scrub radius and the rest of the suspension depends entirely on what the scrub radius etc looked like to begin with (it could be better, it could be worse).. (Scrub radius being a function of how far the steering pivot is from the theoretical 0-line of the wheel; maybe it's at a 41mm offset, meaning the Vectra wheels had a 0 scrub radius to begin with, or maybe it was a compromise already..)

Also has an impact on how the hub is loaded...

Dave the builder's chart above recommends 7Jx16 ET36 wheels for the Vectra. I have fitted 7Jx16 ET32 wheels, ex Omega.
Dave's chart recommends 4 different tyre sizes, 195/60R16, 205/55R16, 215/50R16 and 225/50R16. My Omega tyres are 225/55R16, a bit big for the Vectra, which I calculate will give a rolling circumference 3% bigger than original, and therefore a 3% under-read in speed and mileage. As speedometers usually have 5% flatter, mine will still read fast.

Well it started off about your wife's car droning.

I've been accused of droning on, so it couldn't be your wife doing that? ??? ???

There you are STEMO, I have single handedly got your thread back on track after 5 pages! :P :P ;D ;D ;) ;D ;)

Do you really want reminding that you had that massive bill for a wheel bearing Uncle Stemo  :-\

is she still making annoying noises and what news of the Astra  :D

The astra (and the wife) are fine. And if you think that's a massive bill, you are definitely not a builder.  ;D

I was being facetious taking the P155 , but Massive compared to the £25 it costs me to do a wheel bearing  ;D

You wouldn't get the hub for wifey's astra for £25. Then, of course, you'd have to grunt and fart doing the job and, worse of all, get muck on your hands. Yuk.

The gearbox started leaking from the sealing gasket on to the exhaust, but that wasn't what made me give up. After numerous electrical problems, the headlights decided to just point at the floor. Local garage told me that the lights had their own ecu and, as their kit wouldn't talk to it, the nearest dealer was York. I waited for the oil to stop coming out, i.e. no oil in box, and till it was midsummer so you couldn't tell what the lights were doing, and traded it against a newish astra H at Evans Halshaw. Tee hee.  ;D
