[Steering & Suspension] body shake vibration

[soundlovers]

Hi
Belringo 1.6 NFU 2006 problem:

1. the car only starts for the second time, in the winter it starts for the first time, everything is fine - battery, starter, fuel pressure ok, new spark plugs, coil, ignition coil...diagnostics report no problems. .. what can I check?

2. car vibration, vibration in the body (not in the steering wheel, not in the brakes) tires ok, shock absorbers - test ok, checked in two service centers, they found nothing, only a torn silentblock on the right arm and very little play on the outer half axle...

how to find out what vibration? the car shakes, you can feel it in the seat ... the vibrations start at 50 km h, a maximum of 60 km h, then it stops on the highway, you can hardly feel it. It vibrates while driving even in neutral, it has no effect on gear shifting or braking,

please help what to check ... I don't want to change the semi-axes in a trial and error style ....

thank you very much

Sorry English only as very few of us will be able to understand your question

Would suggest getting wheels balanced and even tyres removed/inspected - the speed-specific vibration sounds typical balance issue.

wheels and tires are fine, balanced, I also put new wheels and it didn't help, it's not the tires, it's shaking in the body, not in the steering wheel

[oilyrag]

OK, so not the wheels!  My disabled converted Berlingo used to make an odd vibration, up hill only and in the wet - it was the exhaust hanger rubbers which had stretched and allowed the exhaust to touch the bodywork (in a spot unseen). I replaced the rubbers, doubled some of them and tie-wrapped others and it all stopped. I guess the wet lubricated the rubber and made it worse. The rubbers are not expensive and easy enough to replace.

hi, I was also thinking about the exhaust - I put new rubber mounts, it didn't help... the vibration is not a metal sound, but a shaking of the car... it shakes even at idle even when I turn off the engine while driving at a speed of 50 km/h-60 km/h, the car shaking... I don't know what to do...

Buckled wheel.

If it only shakes while moving.

[oilyrag]

Well, as the wheels have been changed that could eliminate those.  
If you think that the vibration  might be caused by the drive train itself then you could jack the front and put axle stands under the lower wishbones to load the suspension and run the car in gear at the speed you normally get the vibration. 
It might be caused by a driveshaft , or driveshaft support bearing, but this test possibly wouldn't show up a poor wheel bearing as there would be little load on the hub. Might reveal engine/gearbox mount issue.
There are safety issues when doing such tests - best done outside, rear wheels chocked and hand- brake on.

I missed that Oilyrag, had to re-read.

I realise people's perception varies, but to me a shake is somewhat different to a vibration. So try and describe the effect in a little more detail please.
Obviously you can feel it.
Is there any noise associated with it?
Do you carry passengers or loads, if so, does it make a difference.
You haven't by chance recently fitted a roof rack? I have known those to set up peculiar vibrations and noises.
