I now have a problem.
Cars all finished, wheels all done. Been down the motorway today and found out something major is wrong.
I am now getting bad cabin vibration under acceleration, when i ease off the gas it cruises fine, but as soon as you hit the gas hard, it shakes bad ,seems to be from 60mph onwards. Not noticable around town trotting around.
I did buy an alloy from a well known member on here that was refurbed if people remember, now what im thinking would a badly buckled alloy prior to being seen by me, could possibly give me this problem.
i get no shaking under braking or wheel wobble at a steady speed , just under accelation.
Need to get this sorted before nxt weekend :sad:
cheers for any pointers you can give me on this.

Had the same problem after i had my wheels done and put them back on the car....solved by having wheels balanced
-
Under acceleration its bad, but when i hold the cars speed its smooth as, and the same under braking, wheels smooth and doesnt wiggle in the hand if you know what i mean.
-
^^ Based on that it doesn't sound like the wheel balancing.
Have you recheck your wheel nuts are properly tightened ???
-

Steve, just to clarify it doesnt wiggle in the hand under acceleration either?
I'd expect to hear a knocking if wheel nuts were loose.
-
out of balance imo
-
Pazz, the wheel only vibrates along with the cabin in the front ONLY under hard accelaration.
One other Note car seems to have more Tyre Rumble then before, and tyres are in the same place on the car since the wheel colour changes.
-
ive checked the wheel nuts, all are tight.
One thing i did notice is on the fronts, i have 12 weights on one side in various sizes, and the other has 7 again in different sizes???
-
Where they rebalanced after being painted??
-
Try swapping front to rears and see if there's any difference!
-
Steve,
I had a similar problem,
All it was is the nuts/bolts were lose ( scary to think )
It made a thuddering noise when driving.
Hope you get it fixed pal :happy2:
Just read your previous posts - rushing to think i had the answer, i wrote the above.
I definately would have the wheels balanced... i also had a problem when i got new wheels on my old Golf... when travelling at over 60mph.. the steering wheel would shudder hard.
-
Then I think best to see about getting them balanced. Did they maybe take the weights off to colour code??? :surprised:
Either way most wheels shops dont charge alot to get two wheels balanced. Just unusual for them to just "go out of balance" (if thats the problem).
-
I've had this problem twice on two different cars. The first time it was a dodgy wheel but the second time it was due to a misfire under load, exactly as your describing. I'm not sure but it seems you have just had your wheels done so it stands to reason if it does it now and didn't before then its very likely to be the wheels.
On the other hand it may not so just in case this is what happened to mine (not a golf though). When I drove normally and steady it was fine, not a judder. However when I gave it some gas it used to judder like hell. My mechanic friend said it felt like a misfire and after checking the distributor, plugs and HT leads it eventually got traced to the MAF which I seem to remember was the mass air flow meter and a faulty HT lead that had broken down inside the casing.
Hope this helps if it ain't the wheel mate.

Could this be a coil pack breaking down, i know the weights were removed. the wheels were then sprayed, tyres put back on and Brand new weights were fitted by superTracker which are a well established wheel setting specialist.
Balancing normally would get a wheel wobble on the steering even traveling at a constant speed.
Never had a coil pack go, must admit, does seem simular to slight misfire and makes the car like its "shivering" being a way of describing it.
What to do!!, who to take the car too, Vw for a diagnostic, or Supertracker??? .im sure its not a buckled alloy.
If the alloy was buckled im sure id get a constant vibration on the car whilst travelling.(like being on a push bike with a buckled wheel) oh those good old days.!!
Electronic misfire,under hard accelaration, cant rule that out. Power seems to be there but id say not a crisp as it has been.
-
I'm afraid I'm not very mechanically minded unless its something i've already had experience with and I've only had my Golf three weeks. If its a misfire then there are loads of bits it could be but If I've read previous posts correctly then it could be a coil pack? I took my car to Well Lane Turbo Centre near where I live and they basically put it on the rolling road whilst it was linked up to the diagnostic machine. It didn't take him long to narrow it down and eventually find what was causing it. I don't know how the VW diagnostic works but if it only does it under load maybe the rolling road option would be best?
-
Get it down to the stealers on Monday Steve. Either way they'll find out what it is! :happy2:
-
when wife gets in, im gonna hit the motorway this evening when its quiet to see if i can narrow it down some more.
cheers for the idea's chaps :happy2:
-

yes i think so, shes under good old warranty, so let them find it out :happy2:
-
get the good old vagcom out for some diagnosis :happy2: good luck steve :smiley:
-
Steve
Get her in mate - i'm sure the stealers can sort this :happy2:
:smiley:

Like others have said, you need your wheels rebalanced, by the sound of it.
-
Found anything yet Steve?
-
Tyre pressures?? :confused:
Had a tyre pressure warning light this afternoon , but didnt think too much of it, as outside temp was very hot, perhaps i have a slow punture.
will check those in the morning 1st thing just to make sure.
Cheers for your advice Hurdy and Hedge :drinking:
and others too :smiley:
will update in the morning :happy2:
-
sorry to hear Phil.
Out of interest is it better or worse in a low gear quick accel (2nd) vs 6th gear low revs pull??
the latter may make it worse (by placing more load on the coilpack) and feel rougher...
If its a coil pack the CEL will probably light very soon too :surprised:
on a side note, 12 or 7 weights to balance a wheel that seems already a bit excessive to me...
-
ok, out to get morning papers, rechecked tyre pressures and found one at 30 psi and others 34psi.
Set all wheels by hedges reccommendation of 39psi (2.6Bar) and seems to have improved it slightly but still not great.
accelarate from 70mph to 90ish i get the feeling the balancing is wrong, i can feel ever so slightly wheel shake, but travelling at a constant speed is fine at ANY SPEED, and hasnt lost any performance, so coil pack or missfire i think can be ruled out.
Agree with you John_o, 12 weights seems abit excessive, not sure whether to go back to the place that done the balancing or go somewhere else to see if they agree and redo them.
2nd gear accelation is smooth as , holding any speed is smooth, only apon acelarating from 70 and beyond, it happens.
-
might be a long shot but check the tyres are seated on the rims correctly ! tyre places use too many lazy kids imo !!!!!!!!!!!!!
-
It does sound like a tyre problem in my opinion!
-
rubbers bushes in the wishbones? engine mounts?
-
Almost certainly an excess of Carbon wrapping :evilgrin:
Tyres/balancing I reckon. :happy2:
-
Indeed guys, just to update, swopped my front wheels to the back and vice versa, and BINGO!!, shes now spot on , so tis indeed or was a Balancing issue with an Alloy. It doesnt give any cabin Vibration with it on the back so thats good enough for me.
:drinking:
Roll on next weekend at SC!
-
Woohoo,
Glad it wasn't anything more serious :smiley:
Roll on the Rolling Road day :jumping:
-
Good to hear that Phyllis has stopped with the shakes.
-
Thought balancing maybe the issue.....
Also, just a thought.....have u checked the orientation of the tyres on the rims? They will have a directional indicator on them.
It wouldnt be the first time they have been put on backwards!
On a side note, my previous car a 120D M Sport BMW - I got 4 new tyres fitted to the car when I bought it and believe it or not, the dick that put the tyres on didnt remove the weights on any wheel before fitting new tyres. He then balanced them and added more weights.....and that was a BMW main dealer.
It took 3 visits before they would admit there was a problem....one of MANY gripes about my local BMW dealer...hence I now own my superb GTI
:love:

Yes andy, one of the many things that were checked and all fine.
-
i would get the rear wheels balanced now , all 4 wheels should be in balance really this is often overlooked :happy2:
-
Glad my suggestion worked Steve! :happy2:
-
....
Glad to hear that Phyllis is back to being safe 'n sound :happy2:.
As a next step, swop tyres so that deeper tread is on your rear wheels.
-
Nice one mate. Glad it was nice and simple! :happy2:
