Rear axle bush failure is a common problem on many commercial vans and passenger vehicles, particularly those that regularly carry heavy loads or cover high mileages. The Polybush 39X polyurethane rear axle bush has been developed as a durable replacement for the original rubber bushes, helping to reduce unwanted axle movement and maintain consistent handling.
The 39X is designed for a wide range of Citroen, Peugeot, Fiat, Opel, Toyota and Vauxhall vehicles and replaces several original equipment (OE) references, including 5131 H1 and 9681017080.
The original rubber rear axle bushes are designed to provide flexibility and absorb vibration, but they can deteriorate over time. Heat, oil, road contaminants, heavy loads and repeated movement can contribute to cracking, wear and degradation.
As the bush deteriorates, excessive movement around the rear axle can develop. Depending on the vehicle, this may contribute to:
Replacing worn rear axle bushes can help restore the stability and control of the suspension system.
The 39X polyurethane rear axle bush is designed to provide a longer-lasting alternative to conventional rubber bushes.
Polyurethane offers excellent resistance to oil, chemicals, heat, UV exposure and general road conditions. It also maintains its properties over time, helping the bush provide consistent performance throughout its service life.
The 39X has been engineered to reduce unwanted flex while keeping the suspension controlled and predictable. This makes it particularly suitable for commercial vehicles, fleet applications and vehicles that regularly operate under demanding conditions.
The Polybush 39X is suitable for a range of popular cars and commercial vehicles, including:
Always check the vehicle application and OE reference before ordering.
The 39X rear axle bush replaces a number of original equipment references, including:
These references can help you identify the correct rear axle bush for your vehicle.
Rear axle bushes can handle significant loads, particularly on vans used for deliveries, trades, fleet work, and regular equipment transport.
Repeated rear axle bush failure can result in additional maintenance costs and vehicle downtime. A more durable polyurethane replacement can help reduce the frequency of bush replacement while maintaining consistent suspension performance.
The 39X was developed in response to real-world rear axle bush problems experienced by commercial vehicle operators. Polybush has worked with fleet users, including Royal Mail, to develop polyurethane solutions for demanding applications.
