⚠️ Safety Warning

Working on the drive axle requires lifting and securing the machine. Always use certified axle stands with an appropriate load capacity. Never rely solely on the machine's hydraulics or a jack.

Part's Role in the Machine and Failure Diagnostics

The differential is crucial for the proper operation of the drive system. Its failure, usually a broken tooth on a spider gear, leads to loud knocking, locking of the axle, and in extreme cases, destruction of the entire differential housing.

  • › Loud knocking, metallic bangs from the drive axle, especially when turning.
  • › Locking of the wheels when driving straight or turning.
  • › Complete loss of drive to one axle.
  • › Presence of large metal chunks in the axle oil.

Peace of Mind Guarantee: Why Choose Our Offer?

A damaged differential means an immobilized machine.

Fragments of broken gears can destroy the entire differential, including the housing. The cost of a complete repair kit is many times lower than replacing the entire differential carrier. Don't risk further damage – order a complete GX-AFTER repair kit and restore your axle to full working order.

🔧 Expert's Guide: Key Installation Tips

  1. Maintain absolute cleanliness: Disassembling a differential requires the utmost cleanliness. Any contaminants that get inside can damage bearings and gears.
  2. Thoroughly clean the housing: Before installing the new gears, thoroughly wash and blow out the differential housing of old oil and metal filings.
  3. Lubricate during assembly: Generously lubricate all components (gears, washers, shaft) with clean gear oil during assembly.
  4. Check for play: After assembly, check that the spider gears rotate smoothly and without excessive play.

Frequently Asked Questions (FAQ)

1. What is a differential and how does it work?

A differential is a gear train with the task of compensating for the difference in rotational speed of the wheels on an axle when cornering. The wheel on the outside of the turn travels a longer distance and must turn faster – the differential allows this, preventing stress in the drivetrain.

2. What causes the spider gears to fail?

The most common causes are operation with contaminated or old oil in the axle, sudden shock loads (e.g., "dumping" the clutch on a hard surface), or simply material fatigue after many years of operation.

3. Can I replace just one damaged component?

This is absolutely not recommended. The gears in a differential wear in as a set. Replacing only one component will cause improper meshing, noise, and very rapid destruction of both the new and old parts. You should always replace the entire kit.
