E85/E86 Steering Problems (Solved)

Post by Greg 01 » Sat Oct 10, 2020 9:16 am

Hi guys .
Having just read this thread i wonder if this can solve my steering problem .
At high speed it wonders about a bit and i have vibration in the steering wheel , mainly above 55 and very noticeable at 70 ish .
Ive had the wheels balanced , new front tyres , had all the front suspension checked with no play .
Also hunter alignment done , i had begun to wonder whether i have buckled front wheels so going to have them checked .
My car is a 07 , 30 si roadster .
The wondering around at speed ive gotten used to but add the vibration and its spoiling the whole car .
Hopefully this may be the fix im looking for .
Cheers Greg.

Greg 01 The vibration won't be down to the electric steering, but the wandering could be. When it comes to the vibration, I'd check the following:

1. Wheel balance
2. Brakes (unlikely if vibration happens when you're not braking)
3. Wheel fitment. Are the centre bores of the wheels the correct size for the spigot on the hub?

Spigot is the sticky out bit on the hub that the wheel fits over, my 108's had corrosion on the mating surface when I first removed, I'd check and wire brush any crud off all the hubs and refit with a bit of copper slip on the surface. Whilst they are off examine the tyres for uneven wear bands (alignment issues), 'spotting' or odd bald patches (balance weights, or even shock absorbers). Then run your hand around the tread and feel for uneven lumps or bulges, I've had this on a fairly new tyre causing a vibration and was eventually discovered by a tyre fitter after I had exhausted all the usual suspects.

Hi guys .
Went out for a blast up to blackpool last night and after having the wheels checked and the balance redone the vibration has gone completely.
They did say i have a small flat spot on each wheel but its par for the course with the state of the roads round here .
Happy days , :thumbsup:

Hi. I have fixed a few of these now (100% success rate over five or six cars) but am down in Somerset, which would be a bit of a drive for you. Let me know if you want to come down and we can get it sorted.

Im in Chester and would happily do this for you. shouldn't take more than an hour or so as it needs to be adjusted then tested with further refinement to achieve the right amount. SY14 7BJ

Reamesy in case you want to try a different method, I adjust the ring with the front wheels off the ground. This gives a really sensitive feel, meaning that you can hit the sweet spot in one hit, rather than having to go for test drives and readjusting :)

Me too. Had another go as it just was not perfect. Took 60 miles of driving to get it perfect. The issue was if I got the adjustment right for the higher speeds which was the original fault it felt almost digital at low speed especially when going round round about. It would almost go to sleep then wake again when it received input. Hopefully got to spot on now. as it turns out it only needed 5mm as previously mentioned from where I started.
