Tintop vibration issues...pleasurable but not fun
I have had my polo (GTI with veery low profile wheels as standard) for about 5 months now, it was driving really nicely, and would cruise at *cough*
the speed limit*cough*...
however, for some reason, recently, if I go above about 60 the car starts to vibrate, you can feel it through the seats, steering wheel, peddles
etc....Its quite worrying and really un-comfortable.
Im fairly sure this issue started when I hit an enormous pothole about the size of a bathtub......It had a really sharp edge to it...
Since the problem started I have had the gearbox out, and reconditioned it, whilst it was out I checked all the bushes etc and couldnt see any
faults.
I have also had the front wheels balanced and checked over....
None of the above have cured the problem...
All I can think is that, either the tracking is out (which doesnt really seem right as the car "drives fine" or one of the wheels is
buckled somehow....
Its just odd because if the wheel were baly buckled the tyre wouldnt fit properly and would leak, and the wheel would be hard to balance..
I guess I could get the tyre taken off and run a dial test indicator against the rim and see how true it is...
Does anyone have any ideas atall what might be causing the issue? Its driving me nuts!

Sounds like the same symptoms as our Scenic a while ago. Turned out it was just the wheels out of balance. It cost about £12 to sort out.

Had a similar problem in my scenic - turned out it was because there was a big lump of mud stuck to the inside of the wheel causing it to be out of
balance.
Happens in the back of my mazda because the CV Joints are worn out and the driveshaft is moving around.
Most likely your wheel needs balancing, if not then have you checked for play in any of the joints (Jack the wheel up and wiggle it?)

I had the fronts re-balanced...
Im fairly sure there is no play in any of the bushes....one of the CV joints might be damaged, but its a mission to figure out which one, or if there
is any damage atall...
There was no point in doing the rears as I only have 3ish mm of tread left (new tyres on order)...
once I have the new tyres fitted, they will balance those up, and I will get the tracking checked...but its going to be a couple of weeks before I
get it done because they cant get hold of the tyres I want...

can you drive past the vibration if so it will be wheel balance
if you cant check tyres for mishaped and bent rims
would not think it would be tracking as not lightly to get vibration

Tyre out of shape maybe, try the back ones first if you've had the fronts balanced, jack up handbrake off turn wheels look for any
'wobbly' bits or feels for lumps etc in the tread ....cost nothing and easy to do in a couple of minutes. Hope this helps

Check the tyres and wheels for run out, and lumps.
Out of balance vibration can come from any of the 4 wheels -- even if apears to come up the steering column.
CV joint or drve shaft problem is possible but less likely. I know of one case on a Rover 75 where it was caused by a too much grease in an outer CV
joint.
Also in the good old days of rwd and leaf springs I have seen brake drums out of balance.
In normal use toe in has absolutely no effect on vibration ---
Just to comfort you 90% of tyre fitters haven't a clue about wheel balance other than how to shove a wheel on the machine.

PS Another favourite cause of hard to track down out of balance is caused by tyre fitters leaving half of the old rubber valve stem inside a tyre ater
a puncture repair.

My own experience of tracking is that when it's wrong it gives either heavy steering if it's one way, or skittish and wandering if
it's the other way. The 'way' can vary depending on whether you're FWD or RWD. I've never experienced vibration
because of it.
My vote is for balance (maybe a weight has fallen off), loose/worn steering components or, in the worst case, wheel/tyre damage.

I'd second the possibility of a driveshaft or possibly a wheel bearing on its way out. I had to replace both on my Saxo recently.
Are there any noises along with the vibrations??

Hmmm...there is no noises with the vibration...
but there is some wondering under braking...so perhaps I have a damaged wheel and bad tracking....Both could have been caused when the left side of
the car went into the pothole resembling the grand canyon...

get someone to walk alongside the car to check that a wheel is not wobbling. You can claim damages back from the councel if your car has been damaged
due to pot holes.

Few someone finally mentioned the wheel bearing
All of the above really have you moved the wheels around to see if the sound moves????

As said before it could be a knackered tyre. The internals of the tyre can separate if they get a hard knock especialy if the tyre is not very old as
it is still curing. I used to be a tyre inspector for Uniroyal/Continental and you would be surprised at what can happen to them. Another thing that
can cause a tyre to distort is tyre fitters putting far to much pressure in them to get them to seat onto the rim.
Ps I wish i still had that job
