Scenic 2 rear coils spring coils spring shocks shock absorbers replacing Renault Scenic Grand Scenic

My car, actually the back of it became noticeably lower than it was when I bought it. In fact car become lower within last few weeks. I load it properly when shopping and it is really heavy, however recently it stays lower even after discharging it from shopping stuff...
I decided to replace both coil springs and shocks as well as bumper and rubber, of course with the new plate on top too.
It is hard to get these parts not going to the dealer and n\buying brand new parts. Spring coils and shocks it is not a big problem but buffer, rubbers and plates really difficult to buy. I bought them from 1 website, they have a lot of parts so if you would like details please do not hesitate and contact  me. I will not publish their web in here.

Coming back to the subject. You will need at least 1 proper jack (hydraulic is the best option) and 2 supporters/trestles to put under the car. I have three hydraulic jacks, 2 bought from one of  the "grocery shops" and 1 professional 3.5 tonnes and low profile. In fact I carry 1 jack in my car so in case of flat tire I don't have to wind up and down using the screw thread.

I will skip the steps about removing wheels and lifting up the car. Just for your own safety make sure you secured your wheels properly and engage the car on the reversing gear. It has the lowest ratio (lower than the 1 gear so car would not move) and use some chocks under front wheels (both directions!!!)

Just to see the difference I measured the height from ground thorough the center of the wheel up to the body 67cm

Totally new stuff, I did not use the buffer (blue item)

Shock

Securing wheels.

Now, you can dismantle the automatic park brake and put it back together. I did not take a risk of extra problems/work and switched on ignition (you can do this by locking the door and then putting card into to the slot and push start button for 3-5 seconds), released parking brake and then disconnect the lever from car. Brake stayed released. Switch off ignition. This will cause you an error on the dashboard - famous amber warning Service-Parking brake

Entire back of he car has to be in the air

You may secure it by putting your wheel under the car

Open your boot, remove the floor mat, remove car jack cover

Six bolts have to removed 3 + 3, then lift the plastic cover on the back and slide it forward

On both sides you will find the bolts that hold shock absorber

Under the car remove clip and the plastic cover

Clean the nut with wire brush

You will have to lift your car pretty high and then remove the shock starting with pushing in the bottom bolt, then remove the top bolt, and pull the shock down

Coil spring will go off very easy. Please note what is the position of the coil

In my car, coil was in 2 parts. Had to be changed. The rubber was not that bad, however I had a full new set

Buffer was ok and had a rubber on top. The new one did not have. Buffer was in perfect condition so I used them again

New coil and the rubber. The top should lean slightly towards front of the car

Correct position of coils - the begging of the coil should be at 9 (RHS) and 3 (LHS) o'clock looking from the top of the car.

Put the head of shock in it position and slide in the bolt

Put the coils on the positions. You will need help

Tighten them

Use extra car jack to lift the rear axle subframe. It will lift at the both sides at the same time

Place the bootom bolt into the frame

Washer and nut

and the torque.

Aftermath height changed by 4cm

Good luck.
BTW As mentioned before I can give details to the good online shop, where you can buy all of the parts.
