Why does the reverse horn sound when moving forward after differential replacement?

[Petunia]

Reasons for the reverse horn sounding when moving forward after differential replacement are as follows: Increased rear differential clearance: The reverse horn sounds when moving forward after differential replacement due to increased rear differential clearance, causing the reverse radar to misjudge. Maintenance of the reverse horn: Regularly keep the horn's exterior clean and ensure all wiring connections are secure. Frequently inspect and tighten the horn and bracket mounting screws to ensure proper grounding. To maintain normal horn sound, the horn should not be rigidly mounted; instead, it should be fixed on a buffer bracket, meaning a leaf spring or rubber pad should be installed between the horn and the mounting bracket.
