Bad Bad Vibrations

[Vanbursta]

Help please before I take a big hammer to my Galaxy! (Yes I am tempted), my Gal has developed a really bad vibration between 1500 and 1800 rpm, it happens in all gears. So far I have had, new wheel rims, new tyres, new coil pack, new leads, new CV joints (all 4), wheel balancing (twice), I am about to change the auto box fluid, and a new engine steady bar. I can get out of the vibration by accelerating hard if going downhill, going uphill I have to let the accelerator off until it stops. Seems to be worse under load (ie going up hill etc), sometimes it is really bad and it feels like the car is going to shake apart. Any suggestions or advice would be greatly appreciated as I have run out of both.

Maybe it's worth looking at the engine & gearbox mounts - fi they are shot it might give those symptoms.

 

Has the fault just suddenly appeared or was it a gradual progression?

I'd check belt driven ancilliaries... water pump, aircon compressor, etc.

 

Wierd one this...

definitely sounds like the transmission mounting point failure where the rubber is breaking down.

I have checked tranny / engine mounts and all seem fine. There is a little bit of play in the steady bar but nothing too serious. I changed the transmission fluid on Friday and there was about 800ml too much in there, I am not sure if this could be anything to do with it. Also I went to Frauds to ask if they had the right autobox fluid and they tried to sell me Dexron 111, despite the fact that TIS says don't use it!! I eventually got 4litres of the correct (I hope) orange stuff from the local VW dealer, only problem is that when I drained the old stuff it was red and I am sure it was dexron 111 ! so now of course it is mixed, does anyone know how to empty the whole lot including the torque convertor ? and if the VW stuff (G05) is the correct stuff, or even if Dexron 111 isn't the right stuff.

 

Most worrying of all is that I spoke to the master tech at the local frauds, who said they always use Dexron 111 as it's all they could get despite what it says in TIS!

Had a similiar proplem on my gal,,,,vibration through the car and steering wobble from around 45mph and I could not drive through it,,,,,most replies pointed to the inner cv joint,,,,turned out it was a bent driveshaft,,,,,still not fixed it,,,,

Only way to truely change the fluid is to do several fluid changes! expensive and time consuming, you could drop the sump off the box! and leave it to drip for a few hours in an attempt to remove the majority of it!

So true - even with the drain plug AND level tube removed (see item 23 on the attached pdf), there will still be about a half litre sitting there in the sump.

IMHO If the sump is leaky then no contest - remove it - but I'll bet that gasket (item 22) is expensive (
