54146-45000 BUSH FAQ
How often should leaf spring bushings be replaced?
For commercial fleets, we recommend inspection every 20,000 km. Heavy loading or off-road use may require more frequent replacement to avoid shackle failure.
Does a failing bush affect braking?
Yes. It can cause “axle wrap” or shifting during braking, leading to inconsistent pedal feel and increased stopping distances.
