1. Must be installed in the 4S shop, park the car on a flat floor before installation, and prepare the buffer rubber, jack (if the condition is more convenient on the rack), soapy water (can also be replaced with detergent dilution water);
2. Lift the body of the mounting part with the jack (or lift the whole frame from the upper frame) and the spring is stretched for easy installation. Can fully see the shock absorber spring, no need to rise too high;
3. Spray the soapy water to clean the spring (mainly remove the sand stain on the spring surface), and also spray some soapy water on the cushioning rubber (sufficient lubrication will make it easier for the spring to be seated and calibrated). After installation, thoroughly clean the soapy water. Prevent car safety parts - the shock absorbing spring rusts and breaks, causing human injury;
4. Install the cushion rubber in the middle of the spring (please refer to the installation tips described below), ..., after the wheels are installed, lower the body and confirm that the spring is in the upper and lower slots of the cushion rubber.
