Steyr gears feature high load capacity for heavy-duty rear axles. Most wear failures stem from poor working conditions and improper maintenance rather than quality defects.

Overload operation and frequent slope starts cause excessive meshing pressure and tiny tooth surface damage. Dirt-mixed lubricant accelerates abrasive wear and peeling. Mixed or overdue gear oil leads to invalid oil film and dry friction under high temperature.

Blocked vent holes cause internal pressure rise and oil leakage, greatly shortening gear service life. Standard lubrication and correct driving habits can effectively reduce wear and keep the rear axle stable.
