Center mounting bracket for the rear of the car - for the purpose of the fender
A center mounting bracket is installed at the rear of the car. If it is for fixing the mudguard, it usually refers to the rear bumper bracket or the rear wheel mudguard bracket. Its main function is to provide support and cushioning for the rear bumper and mudguard, preventing the vehicle body from being damaged by mud, sand, and stones.
The function of the bracket
Support and fixation: It ensures that the mudguard is firmly attached to the rear of the wheel, without loosening or shifting due to bumps.
Buffer and protection: In case of minor collisions, it can disperse the impact force, protecting the rear bumper, mudguard, and rear structure.
Anti-corrosion and anti-scuffing: Together with the mudguard, it reduces the damage to the car paint and chassis components caused by mud and stones.
Installation tips
Align and then lock: The rear wheel mudguard has a larger curvature, so it is recommended to check the fit first before tightening the screws to avoid uneven force and edge warping.
Tools preparation: A Phillips screwdriver, corresponding screws or clips, and some owners suggest having a universal glue for reinforcement and anti-loosening.
Self-check after installation: Drive the vehicle in place to fully apply the steering wheel and confirm there are no scratches or abnormal noises; then test the bumpy road surface to see if it is loose.
When installing, be careful to avoid the sensor or radar area at the rear of the vehicle to prevent obstruction and functional interference.
There is no official unified definition for "center mounting bracket for the rear of the car" in the public information. When purchasing, you can search for "rear bumper bracket" or "rear wheel mudguard bracket" and confirm if it is compatible with your vehicle.
If the mudguard installation bracket at the rear of the car fails, the most common reason is that the fixing bolts are loose or have fallen off, causing the bracket to lose its restraint and produce abnormal sounds, shaking, or even fracture during driving vibrations.
Troubleshooting and solution steps
Check the fixing bolts: First, check if the bolts connecting the bracket to the frame are loose or fallen off. This is the primary cause of the bracket failure. In heavy truck cases, the bracket fracture was caused by abnormal loosening of the bolts.
Check the bracket itself: Check if there are cracks at the bending corners (especially the R corner) of the bracket. This area is a stress concentration zone and is prone to fatigue cracks under alternating loads.
Check the mudguard clips: The plastic clips that fix the mudguard near the wheel arch may be aged and broken, causing looseness and abnormal noise. This situation can be solved by replacing the clips.
Re-tighten: If the bolts are loose, use a torque wrench to tighten them according to the force required by the vehicle manual. The design torque for the M14 bolts of heavy trucks is approximately 180 N·m, which can be used as a reference.
Replace the damaged part: If the bracket has broken or the clips are damaged, a new part needs to be replaced. Pay attention to vehicle model matching when purchasing, such as for the Outlander and N1 models, there are dedicated replacement parts.
If the bracket has cracks or fractures and continues to be driven, it may cause the mudguard to fall off, affecting driving safety. It is recommended to replace it as soon as possible.
Reference for purchasing parts
General parts: Rear middle mudguard installation bracket assembly (model 100510302270), can be searched by model on the auto parts platform.
Special parts: Some models such as N1/N1s have strengthened modification brackets that are easy to install and more durable.
If after self-checking you still cannot determine the cause of the failure, it is recommended to go to a repair shop and have a professional check it. This will be handled more quickly and safely.
