Volvo Hub Oil Seal 11103124
OEM & Aftermarket Volvo Wheel Hub Oil Seals Available from Truckers Plant Parts
The wheel hub oil seal is one of the smallest components found within a Volvo articulated dump truck, yet it performs one of the most important jobs on the entire machine. Without an effective oil seal, the expensive bearings, planetary gears and final drive components inside the wheel hub are left vulnerable to lubricant loss, contamination and premature failure.
One such seal is Volvo OEM Part Number 11103124, a hub oil seal used on a number of Volvo articulated haulers including the A25D, A25E, A30D, A30E, A30F and A35D. This seal is designed to retain lubricating oil within the wheel hub while preventing mud, water, dust and abrasive material from entering the axle assembly.
Although relatively inexpensive compared with many drivetrain components, replacing a worn hub seal at the correct time can prevent repairs costing thousands of pounds.
At Truckers Plant Parts, we supply OEM-quality aftermarket hub seals and sealing components for Volvo articulated dump trucks, wheel loaders, excavators and many other Volvo Construction Equipment machines. Whether you require a single replacement seal or are carrying out a complete axle rebuild, we can help source the correct components quickly and competitively.
What Does a Wheel Hub Oil Seal Do?
The wheel hub assembly on a Volvo articulated hauler contains a sophisticated combination of taper roller bearings, planetary reduction gears, shafts and lubricating oil.
These components operate under extremely high loads every day. As the machine travels over rough terrain carrying payloads of 25, 30, 35 or 40 tonnes, enormous forces are transmitted through the wheel hub.
The hub oil seal performs two critical functions.
Firstly, it prevents valuable lubricating oil from escaping the hub assembly.
Secondly, it prevents dirt, dust, sand, mud and water from entering the bearings and planetary reduction gears.
If either of these functions is compromised, serious mechanical damage can occur surprisingly quickly.
Why Hub Seals Eventually Wear Out
Wheel hub seals are continually exposed to some of the harshest conditions experienced anywhere on an articulated dump truck.
Every journey through mud, standing water, abrasive quarry dust or loose aggregate places additional stress upon the sealing lip.
Over time the flexible sealing material naturally hardens through age, heat and continuous rotation.
Small grooves may also develop on the shaft surface, reducing sealing efficiency.
Eventually the seal can no longer maintain adequate oil retention.
Once this occurs, lubricating oil begins escaping while contamination starts entering the hub assembly.
Ignoring these early warning signs often results in much larger repair bills later.
Common Symptoms of a Failed Hub Oil Seal
Recognising the symptoms early can prevent extensive drivetrain damage.
Typical warning signs include visible oil around the wheel hub, wet brake areas, oil running down the wheel rim, contamination around the hub, unexplained lubricant loss and excessive dirt collecting around the seal area.
Operators may also notice unusual bearing noise, increased hub temperatures or signs of oil contamination during routine maintenance inspections.
Addressing these issues promptly often prevents damage to bearings, gears and other expensive axle components.
Volvo OEM Part Number 11103124
Volvo Part Number 11103124 is an oil seal used within the wheel hub and axle assemblies of several Volvo articulated dump truck models. Public parts references identify it for machines including:
- Volvo A25D
- Volvo A25E
- Volvo A30D
- Volvo A30E
- Volvo A30F
- Volvo A35D
Equivalent listings also describe it as an axle sealing ring or wheel hub oil seal depending upon the catalogue terminology.
As with many Volvo components, it is always advisable to confirm compatibility using your machine serial number before ordering.
OEM or Aftermarket?
Many owners automatically assume genuine manufacturer parts are the only suitable option.
Today’s aftermarket industry tells a different story.
Many OEM-quality aftermarket seals are manufactured using premium rubber compounds such as NBR or FKM (Viton), precision-machined metal carriers and high-quality sealing lips designed specifically for heavy construction equipment.
When manufactured correctly, these components provide excellent sealing performance while often offering significant cost savings.
For fleet operators maintaining multiple machines, those savings quickly become substantial.
More Than Just One Seal
During a hub rebuild, replacing only the leaking seal is not always the most economical solution.
Many workshops choose to inspect or replace associated components at the same time, including:
- Taper roller bearings
- Bearing cups
- O-rings
- Hub gaskets
- Lock washers
- Wheel studs
- Wheel nuts
- Hub shims
- Planetary gears
- Bearing spacers
- Hub retaining hardware
Carrying out preventative maintenance while the hub is already dismantled often saves considerable labour costs in the future.

The Right to Repair
The growing Right to Repair movement has transformed heavy equipment ownership.
Owners increasingly expect the freedom to maintain and repair their own equipment using OEM-quality replacement components rather than relying exclusively on manufacturer supply chains.
Truckers Plant Parts fully supports this approach by offering premium aftermarket components that meet the demanding requirements of modern construction equipment.
This provides customers with greater flexibility, lower maintenance costs and faster access to the parts needed to minimise downtime.
Keeping Volvo Machines Working
Volvo articulated haulers have earned a worldwide reputation for reliability and long service life.
Many continue operating successfully for well over 20,000 hours.
Achieving this level of durability depends upon routine maintenance and timely replacement of worn components, including seemingly simple items such as wheel hub oil seals.
Replacing a hub seal before contamination reaches the bearings can prevent thousands of pounds of unnecessary repair costs.
It is a small investment that protects one of the most valuable assemblies on the entire machine.
