no worries. I will have to book it in to see you next time I'm down near the big smoke.

in Chester, so miles away.

Nope you cant drive through it. The car has had a few problems that I have slowly got the the problem of over the last 12 months, Tram-lining, brake judder, springs snapping(In the middle), new wheels as I had some small buckles in the old ones.. So as the problems have been got rid of this has been left so to speak. I noticed it as my wifes car doesn't do it (z4). Its a difficult one, but then its an old car. I wonder if replacing all these parts is just showing up worn parts further down the line no matter how small?

ok I have taken notice today: - you can feel it at low speeds its more intense at higher speeds - It feels like you can feel the road surface through the floor and wheel - I have pumped the tyres up to BMW door specs so 35 from 42 rear and the effect is better (so less) - The rougher the surface the worse it is, the car was much better coming home than going? maybe its the effect of the 18" wheels and low profile tyres and harder poly bushes? I jacked the car up and cant see and movement on the bottom ball joints with a bar under the tyre, if there is any I'm not seeing its nothing like the youtube vids. Maybe its something I have to live with..

On the wheel and in the floor. no you cant drive through it, however I haven't tried anything over 77 your honour I will try tomorrow if nothing is about.

constant fast pace vibration, I dont get it around town its a only when the car is moving at motorway speeds.

He must have got to the point where he thought it wasn't fixable?

Is there a test for shockers? I know the MOT man is just looking for a leak, however how do you know when they are past their best? I still have an issue with a vibrations at speed on the motorway I can feel it through the floor and the steering wheel. I have had ball joints checked and geo re-done and brake reaction bushes changed. Its an annoying vibration, I was thinking that the shockers might not be keeping the wheel under control at speed. Anyone have any tests, as the 1970's bounce test doesnt seem to do much these days. Thanks Graham

holy smoke.

where did the first thought come from to jump out???

Well just as an update I have cancelled the bush replacement on the car, the handling has returned its got to be a good 85% better. There is still a slight tram-line effect in the heavy ruts, however the pulling to the left, steering wheel vibration has gone. In fact I cant believe its so much better after that last Geo. I would love to get down the WIM in the future and have some of the front camber dialled out. I have been so paranoid I went out after I got home and recorded the tyre pressures too, 31.5 psi front and 37.5 psi rear I understand that these will bee effected massively by the -5 deg temp. Going to work this morning it was -11 at 09:30 am. Just wanted to update this thread so I can plot any issues. touching wood I'm a happy bunny so far..

I presume the springs has changed the max amount of adjustment and the fact they wont all be the same from new, I also presume the only fix to this would be a custom threaded arm. I was shocked when I was watching him how much the the wheel moved you could see it as he was turning the spanner..

You should see my mum drive...

ok as an update I went back to Buckley Tyres where I had the geo done and asked for my last printout which I then discussed with guys there and they offered to re-check it as the settings looked out to me. (See old second steering rack) I stayed with the guy and asked for less rear camber, this was dictated by the passenger side rear adjuster which is at its max positive setting. ( if thats the right word) the drivers side was then matched, I asked for the caster to also be recorded. I have driven the car back about 8 miles and the car feels more neutral buts its hard to explore the handing in these conditions... I will know on the 50 mile drive to work on Monday.. I have the car booked in to switch the bushes back to BMW OEM spec next week. I will see what its like as spending all this cash before Christmas doesn't impress the wife much.. Anyway data below: Old settings Today's new settings

Tony, I drove my wife's Z4 into work today, and I know here front bushes are going, I noticed the feeling is totally different. - The wife's car wanders but the steering wheel doesn't. Hover there is hardly any vibration unlike my car. - My car pulls left and right but the steering wheel is moved or tugged, I also find my self some times turning slightly left or right to keep it in the straight line. Have you found the poly bushes being too stiff and transferring vibration and not giving, so forcing the wheel to over? I'm starting to think they were a bad idea. I have found one other post on BMWLND someone complaining that the poly was too stiff?
