If we want to replace the car shock absorber, we need to remove the large screw under the shock absorber first. If we want to remove the big screws, we need to loosen the wheels in diagonal order first. Then use the jack to lift the car, and then you can remove the big screw below. Open the hood of the engine and loosen the fixing nut on the upper end of the shock absorber. Then we can take the shock out of it and slowly put it where it can be operated. Then we can completely unscrew the nut connecting the shock absorber to the body.
In fact it's not difficult, you just need to have the corresponding tools.
