When Replacing The Shock Absorber, You Need To Pay Attention To The Following Issues: I. Preparation 1. Prepare the right tools Before replacing the shock absorber, prepare the necessary tools, such as wrenches, sockets, jacks, screwdrivers, etc. 2. Ensure safety When replacing the shock absorber, be sure to ensure safe operation. Park the vehicle on a flat, solid ground, pull up the handbrake, and start the parking brake. You can use a jack to lift the vehicle to facilitate the replacement of the shock absorber, but pay attention to safety when operating the jack to ensure that the vehicle is stable. II. Precautions during replacement 1. Correctly disassemble the old shock absorber When disassembling the old shock absorber, follow the correct steps. First loosen the bolts and nuts that connect the shock absorber to the body and wheel, but do not remove it completely. Then use the jack to lift the corresponding part of the vehicle, so that the shock absorber is in a relaxed state, and then completely remove the old shock absorber. 2. Install the new shock absorber When installing the new shock absorber, ensure that the shock absorber is installed in the correct position and the bolts and nuts are tightened with moderate force. You can refer to the vehicle's maintenance manual or consult a professional auto repairman to learn the correct installation method and tightening torque. 3. Check other parts When replacing the shock absorber, check other parts related to the shock absorber, such as springs, suspension ball heads, rubber bushings, etc. If these parts are found to be damaged or worn, they should be replaced in time to ensure the normal operation of the vehicle's suspension system. III. Debugging and inspection after replacement 1. Perform four-wheel alignment After replacing the shock absorber, the vehicle's four-wheel alignment parameters may be affected. Therefore, it is recommended to perform four-wheel alignment adjustment to ensure the vehicle's driving stability and normal tire wear. You can go to a professional auto repair shop or tire shop for four-wheel alignment detection and adjustment. 2. Test the shock absorption effect After replacing the shock absorber, take a test drive to test the effect of the new shock absorber. Pay attention to whether the vehicle's driving stability, comfort and shock absorption effect have been significantly improved. If problems are found, they should be checked and adjusted in time. For example, during the test drive, pay attention to the performance of the vehicle under different road conditions, such as the shock absorption effect when passing through bumpy roads, stability when driving at high speeds, etc. Pakage includes: 2* Hood Shock Note: Please check the OE number and model number carefully before purchasing to make sure it is what you need.
