Strange noise

[Matt21385]

When im driving along the road with no music on I can hear a slight thumping sound coming from the driver side rear wheel. A guy I worked with heard it & thought it might be the wheel bearing that was needing fixed. Can anyone help? :(

Wheel bearings are usually more of a droning noise. Maybe more suspension related? (just a guess).

Its hard to explain the sound really. Think ill have to get someone to look at it :(

[david-bell]

sounds like a shock absorber matt maybe :(

Thats the thing, I have changed to Koni shocks and I still get it. Its a repetitive noise. For example, the faster I go the more constant the noise is. if you know what I mean?

do we have suspension rubber bump stops on our suspension???

:flail: Yes we do :rolleyes:

Think of the noise you would get if you had, say a stone in your tyre. Its sort of like that but only a vey slight thumping sound. Cant think of a better way to explain it. So it constant, the faster I go, the more frquent the noise.

I thought it might be an anti roll bar bush but it does not sound like it as it goes faster when you go faster, might sound a daft idea but you might have got a tyre that is out of round, what about putting the spare on and seeing if the noise is still there, that would then eliminate the tyre..

Yes ed i agree with you :clap:

When you take the wheel off, take a look to see if there is any thing rubbing against the wheel, some wire or any thing of the likes, doesn,t sound like it to me, but worth a look.

Hi There, I was wondering if you managed to fix the thumping noise on your vectra, I have the same symptoms on my signum.

In light of the tyre recall on Goodyear Eagle NCT5's check your tyres to see if one of them is delaminating !!!!!!!

i have michelin primacys on the front and had original goodyears on the rear until i found a bubble on the offside inner wall, I replaced this tyre with a new goodyear nct5. the only original goodyear is the nearside rear goodyear nct5. The rumbling noise from the front is annoying, vauxhall took it for 2 test drives and I wasnt convinced he could hear the noise i could hear. He replaced sum bushes and track rod ends but it never went away. The cars steering feels strange at times, like driving around with flat tyres, like a bike with buckled wheels. This is with all tyre pumped to 30psi. I was debating getting all 4 shockers swapped, dealer price was £475 inc fitting and VAT. The technician though the shocks were ok, I felt as if he was telling me this is how the Signum feels. Its a lot of dosh to waste if the cars no different afterwards.

I wouldn't waste all that money on dampers on the off chance it may be them it sounds more like you should get the steering rack checked out properly first as i know there has been some issues with them in the past

If the noise from the front is deffo a rumble then i am fairly certain its wheel bearing related as this is a well known weakness on early Veccy's mine is a "52" plate and has had 3 rear and one front in less than 40,000 miles !!!!!

I think I will take it to a different dealer and see what they think, some dealers charge money just to look at the problem, and if they dont/cant find fault thats £70 gone. Mine is a Signum 04 plate 2.2dti, I test drove a vectra 3.0cdti once and it was awsum. I could do with test driving another Signum to see if it drives any differently. How can I tell if my 1 remaining original Goodyear is the faulty type?

that should explain it for you..

[GaryJ]

Thanks for that, I dont think mine Is 1 of them, cant see a code on the tyre at all, and it says made in Germany not Solvenia. Shame cos the tread is getting low. I will ring the dealer tomoz regarding the rumble. Thanks
