Shocks and coils replacing on the front of Grand Scenic 2
Remove nuts
covers,
and wipers
use some penetrating liquid like wd40
Remove wheel
Clean up (wire brush) all bolts/nuts related to a shock
My hydraulic car jack failed when pin slided on the side
and damaged the jack. However I always secure my car by putting wheel under the chassis just
like on this picture. Right, let get back to job...
remove bolt holding bottom of the shock
remove 3 bolts holding upper strut mount
pull down the shock (pull it by coil) and help yourself by pushing disk down with your foot pivot arm
old shock and coil
The worst ever thing I had to deal with. Compressing the coil. It took me about 1.5hr for each coil to compress and decompress, so over 6 hrs to swap the coils. At the end the tread on jaws was totally damaged and jaws landed in bin.
It was very late and I did not have any tar (all shops were closed), so I simply heat up some butter in microwave and put it on rubber parts of strut. May sounds funny or stupid however it works ;)
Of course don't forget to clean it before applying "butter"
New coil compressed
Placing new coil on new shock
Instruction says that 62Nm has to be used for tightening strut and shock. You will have to use Allan key and right spanner and tighten it as much as you can. Then use just dynamo-metric key at 62Nm torque.
Ready to go McPherson
It helps a lot if you have another car jack. I used to lift up entire suspension and to place upper strut in its final position
21 Nm, yes it is. Just 21 Nm for each bolt holding the strut (I was surprised too)
Be eco friendly. Washing up liquid or water with soap will wipe the stain from the ground
Because of spillage I had to add some oil to gearbox. It was maybe 70-80ml. Not much. Oil type is 75W80. On picture you can see where is the control/top up cap. It is tight in there. I used a bottle after ketchup, wash it up fill it with oil and topped up missing oil. No special tool needed.
At the very end put back wipers, make sure you adjust them before tightening.
Thanks
