⚙️ Grooves in a Pinion Yoke – Small Damage, Big Problems ⚙️
This pinion yoke has deep grooves worn into it from the old seal. Over time, the rotating seal lip can cut into the yoke’s surface, especially if the seal gets dry, contaminated, or overheated.
Those grooves may look minor, but they can cause:
💧 Constant gear oil leaks
⚠️ Contaminated differential fluid
💸 Premature wear on bearings and gears
When we find this during a repair, we don’t just slap a new seal on and call it done that’s only a temporary fix. We either replace or sleeve the yoke so the new seal seats on a smooth surface, ensuring a long-term, leak-free repair.
Proper inspection and repair now prevent costly differential damage later.
