The lifespan of rubber sealing strips for frameless doors is usually only 4-5 years. We carefully press the sealing strip at the edge of the roof to check for loss of elasticity and use a high-pressure water gun to wash the seams of the windows to check for direct water leakage due to aging.

Absolutely. The extreme temperature fluctuations will significantly accelerate the aging of chassis rubber parts, oil seals, and interior plastics. For vehicles frequently dispatched across such latitudes, we will conduct fatigue resistance checks on chassis rubber parts that are twice as stringent as those for vehicles in temperate regions.

We maintain an extremely cautious and firm denial. Some platforms may cater to such demands for orders, but converting left-hand drive to right-hand drive involves complex steering column cutting, firewall structure changes, and wiring harness reorganization. This non-factory deep modification poses significant safety risks and is very difficult to pass vehicle safety inspections in developed countries (such as Japan's earthquake test and the UK's IVA test). Out of responsibility for safety and long-term reputation, we refuse to provide any steering conversion services that damage the vehicle's underlying structure.
