Geo is a work of art and requires someone who really understands how to use the equipment. I had a s2000 and a proper geo setup absolutely transformed the car a rubbish one made it worse. Ideally the rrs should be set up with the engine running ensuring the suspension is at driving height, not off so the vehicle tris to level its self.

Hi Jonathan have you managed to fix this problem as I have the same issue ?

Folks - advice/help required. before we start this IS NOT a wheel balance issue!

On 2 occasions in 4 days I have been on the motorway, 70 to 80 miles and hour - been travelling for 1/2 hr and 15 mins - I get a strange vibration, not through the steering wheel, across the whole of the car (a bit like rear wheels unbalanced), after a couple of minutes it fades away.

This morning I drove all the way to Birmingham, no problem.

Bizarre.

Any suggestions?

Cheers

Jonathan

I would suspect a gearbox issue, I had the same judder every now and agin until it let go, maybe a mega flush would help, though it didn't do anything for mine  07,TDV8,Black, Black Heated leather all round, Rear Entertainment with Headpones & Remote, TV, DVD, Pure Dab Digital Radio, Sidesteps, Adaptive Headlights, sunroof, now working fuel burning heater )))

I have a similar issue on my rrs. My11 with 62,000 miles on it. I had the gearbox oil replaced last Christmas with 55,000 miles on the clock. The vibration is very intermittent. Sometimes I can drive longer distances and there is no sign of it and yesterday it was very noticeable. I slowed from 80mph to under 60 and it stopped and it was fine t accelerate again. P.s. I was on a German autobahn before anyone mentions the speed . Also I've just stopped to my winter tyres and my summers are not wearing unevenly and the vibration is still intermittent

have you ever used tyre weld in any on the wheels

No, they are all tubeless and haven't had punchers. The winters are 3 years old and the summers are 2 and 4 years old.
