What causes axle leak?

Axle leaks are typically caused by the deterioration of seals or gaskets due to age, wear, or exposure to contaminants. Damage from road debris, improper installation, or excessive heat can also compromise these seals, leading to fluid leakage. Additionally, overfilling the axle or using incorrect lubricants may increase pressure and contribute to leaks. Regular maintenance and inspections can help identify and prevent axle leaks before they become significant issues.
