What Makes a 400EX Swing Arm Bearing Essential for Performance?
Reduced friction leads to better performance, as it allows the swing arm to pivot more freely, which can enhance acceleration and cornering capabilities. Bearings that feature advanced lubrication technology can further reduce wear and enhance longevity.
Improved stability is a direct benefit of having effective swing arm bearings, as they keep the rear suspension aligned properly. This alignment is vital for maintaining traction and balance, particularly when navigating rough or uneven surfaces.
Easy installation is a significant advantage, especially for DIY enthusiasts. Many top-rated swing arm bearings come with user-friendly designs or kits that include all necessary hardware, simplifying the replacement process.
Maintenance-free options are appealing for those who want to spend more time riding and less time on upkeep. Sealed bearings prevent dirt and moisture from entering, which means that they can perform optimally without frequent lubrication or inspection.
What Are the Common Signs Indicating a Worn Swing Arm Bearing?
Poor handling can significantly affect the safety of riding, as worn swing arm bearings can alter the vehicle’s geometry and responsiveness. Lastly, if maintenance is required frequently, it often points to underlying issues with the bearings, suggesting they may no longer be capable of retaining grease or managing the stresses of operation effectively.
What Key Features Should You Consider in a 400EX Swing Arm Bearing?
When selecting the best 400EX swing arm bearing, several key features should be considered to ensure optimal performance and durability.
- Material Quality: The material of the bearing plays a crucial role in its longevity and resistance to wear. High-quality materials like high-grade steel or aluminum are preferred as they withstand heavy loads and resist corrosion, thereby enhancing the lifespan of the bearing.
- Seal Type: The type of seal used in the bearing can significantly affect its performance. Sealed bearings help to protect against dirt and moisture ingress, reducing the risk of contamination and prolonging service life, while open bearings may offer less friction but require more maintenance.
- Fit and Compatibility: Ensuring that the bearing fits correctly within the swing arm of the 400EX is essential for optimal functioning. A precise fit prevents excessive play, which can lead to increased wear and instability during operation.

- Lubrication Type: The type of lubrication (grease or oil) used in the bearing affects its performance and maintenance requirements. Bearings that are pre-lubricated and require minimal maintenance are generally more desirable, as they save time and effort in upkeep.
- Brand Reputation: Opting for a swing arm bearing from a reputable brand can provide additional assurance of quality and reliability. Established brands often have proven track records and customer reviews that can guide buyers towards making the best choice for their 400EX.

To properly install a 400EX swing arm bearing, follow these essential steps:
- Gather Necessary Tools: Ensure you have all the required tools, including a socket set, torque wrench, bearing puller, and grease.
- Remove the Swing Arm: Carefully detach the swing arm from the frame, making sure to keep track of all bolts and spacers.
- Clean the Area: Thoroughly clean the swing arm and bearing housing to remove any dirt or debris that could affect the new bearing installation.
- Press in the New Bearing: Use a bearing press or appropriately sized socket to gently press the new bearing into the swing arm until it is fully seated.

Gathering the necessary tools is the first step to ensure a smooth installation process; this includes a socket set, a torque wrench for proper tightening, a bearing puller if you need to remove old bearings, and a good quality grease for lubrication.
Removing the swing arm involves loosening and taking out the bolts that connect it to the frame; it’s important to keep track of any spacers and washers, as losing them can complicate reassembly.
Cleaning the area is crucial, as dirt or old grease can hinder the performance of the new bearing; use a degreaser and a clean cloth to wipe down the swing arm and bearing housing thoroughly.
When pressing in the new bearing, it’s important to use even pressure; a bearing press or an appropriately sized socket can help you avoid damaging the bearing during installation.
Lubricating the bearing with grease before installation helps reduce friction and wear during operation, which can extend the life of the bearing significantly.
Finally, when reassembling the swing arm, ensure that all components are aligned properly; use a torque wrench to tighten the bolts to the manufacturer’s recommended specifications to prevent any issues while riding.
