Slt,

Be careful, put the car on the ground before tightening the 2 shock absorber fixings, otherwise the silentblocs will be under permanent stress and this will cause premature wear.

Thank you very much for sharing and the photos, this kind of tutorial is unfortunately lost. Thank you in any case 👍

On Scenic II phase 2: All the video tutorials show lowering the car before tightening hard. So, we don't really see the point of measuring the 432.5 (mm!?!?) indicated above. And the shock absorber would have to be placed to within 0.5mm?! Not very credible...

Personally, I prefer to leave all 4 wheels in place. I still lift them with the jack to loosen the suspension a little, but I'm not even sure it's necessary. At worst, it helps to get under the car...

Be careful when unscrewing/rescrewing the nut in step 6-8 above: the standard Facom 18 socket is not deep enough. It is impossible to unscrew with it. I had to use a flat wrench. But it is not suitable if you want to re-tighten with a torque wrench with socket...

Tutorials and instructions from some brands indicate that you should also run the shock absorber vertically for a few strokes before installing it, to expel any air that may have been trapped in the liquid due to flat storage.

Caution! The shock absorber length (measured between its fixing points) should be adjusted to 432.5 before tightening the fixings to the prescribed torque. 6 at the top and 10 at the bottom (Dan.M).

Failure to do so will overstress the silent blocks and cause them to eventually tear.

Hello

What is the tightening force of the nuts?

THANKS
