Bestselling Differential Oil Seal 02Q409189B for Volkswagen Tharu

Core Selling Points

Popular sealing component for bulk centralized purchasing

100% OEM dimensional compliance, direct press-in installation without any modification

Applicable Vehicle & Installation Information

• Main applicable model: Volkswagen Tharu (280TSI / 330TSI two-wheel drive & four-wheel drive versions)
• Compatible extended models: VW Tiguan L, Golf, Passat B8, Audi Q3 and other VAG models adopting the same differential sealing structure
• Matching power units: 1.4T / 2.0T turbo gasoline engines
• Installation position: Dynamic sealing part for the output shaft of the front drive differential

Optimized Durable Structural Design

1. High wear-resistant nitrile rubber sealing lip: Excellent oil resistance and heat resistance, closely fit the rotating surface of the drive shaft to effectively block gear oil leakage
2. Stamped steel outer skeleton: High structural rigidity, not easy to deform during pressing installation to maintain stable assembly tightness
3. Built-in constant force tension spring: Keep the sealing lip clinging tightly to the shaft surface for a long time to compensate slight abrasion of the lip body
4. Anti-rust treatment on metal shell surface: Resist erosion from chassis muddy water splashing and corrosive substances
5. Independent finished product structure, ready for direct installation and use

Core Functions & Drive System Protection

1. Form reliable dynamic sealing between differential shell and drive shaft to prevent outward leakage of internal differential lubricating oil
2. Isolate external mud, water and dust from entering the differential cavity to avoid abrasion and corrosion of internal gears and bearings
3. Maintain a good lubrication environment inside the front differential and extend the service life of each drive component
4. Eliminate abnormal running noise generated by dry friction of differential parts due to oil shortage

Solvable Common Fault Phenomena

• Obvious oil stains or oil dripping traces at the front differential position after parking
• Abnormal buzzing and friction noise coming from the front wheel side while driving
• Rapid decline of differential oil level requiring frequent oil refilling
• Premature wear and abnormal clearance of differential internal gears and bearings
• Mud and impurities entering the differential leading to component corrosion damage
