Removing a car bumper requires following a standardized process to ensure safety and component integrity. First, securely park the vehicle on a lift and engage the safety locks, then raise it to a suitable working height. Use a wrench or screwdriver to sequentially remove the mounting bolts on both sides and the bottom of the bumper (for some models, it's necessary to first remove the fender or screws inside the boot lid). When disconnecting the taillight wiring harness or reversing radar's electrical connector, gently press the release tab to avoid damaging the wiring. Modern bumpers predominantly use lightweight plastic materials that combine impact resistance with corrosion resistance, with designs emphasizing seamless integration with the vehicle's contours. During disassembly, note structural variations between models-for instance, some may require removing front grille screws or adjusting wheel alignment first. If any operational uncertainties arise, professional technicians should be consulted to prevent paint damage or component deformation from improper removal. During reassembly, secure components in reverse order and ensure all bolts are torqued to the specified 70Nm standard.
