Mate of mine bought a 1998 (I think, MK4 1.8T anyway) Golf GTI recently with about 90,000 miles on it.

When it's on gentle to medium acceleration the whole car shimmies from side to side. It's not through the steering like a wheel balance issue, you feel it most through the seats. And it's not rapid like a wheel balance or a vibration either, I suppose it's a couple of shimmies a second.

It's most noticeable when pulling up hills, particularly in second or third gear at around 30-40mph.

Bit of a loss as to what it could be, anyone got any suggestions?

If it were rear wheels, rear wheel bearing etc, would it not do it all the time? It's the fact that it only does it under power that makes me wonder whether it's drive train related?

It's not a bent wheel or wheel balance because it only does it under load, it's perfect on even throttle or decelerating.

Then noticed I need a new set of top mounts and one of the wishbones' bushes is perished. But apart from that, Voila! Wobble/shimmy all gone, nearly happy.
Fantastic!! Well done buddy! smile

But now I can drive the darn thing, I've noticed a nasty resonance between 3,800 and 4K rpm, maybe the exhaust was damaged from the excessive engine movement? Quite peculiar. Any ideas???
Does sound like it could be the exhaust.

On the first day, I actually excremented myself as the whole car suddenly shook itself violently at 40mph,
I'm not sure excremented is a word.

I need to have a quiet word with you about the Pistonheads Spelling and Grammar Police. They're ruthless... cop
