~~~~~~
Q: How do I know if my front wheel bearings are bad?
A: Common signs of worn front wheel bearings include play in the rear wheel, rough or gritty rotation, unusual noise while rolling, and inconsistent handling. If you feel looseness at the wheel or notice accelerated seal wear after muddy or wet rides, it may be time to service the hub.

Q: What makes the Factory Links Race Series® kit different from standard wheel bearing kits?
A: Race Series® Low-Friction Wheel Bearing Kits are designed for racers who want maximum performance and durability. The kit uses unique low-friction Teflon seals to reduce drag and improve wheel efficiency while still providing strong protection against off-road contamination.

Q: Does this kit include seals and everything needed for a full service?
A: Yes. Factory Links wheel bearing kits are built to include everything needed for a complete service of your wheel hub.

Q: Is this kit good for riding in water, mud, and dust?
A: Yes. Factory Links bearings feature dedicated Designdust® seals designed to help protect against intrusion from common off-road contaminants such as water, mud, and dust, improving service life in harsh riding conditions.

Q: Will this kit fit my exact bike?
A: This kit fits select Triumph TF models. See the Fitment Tab above for the complete fitment list or search by Year/Make/Model to confirm your exact application before ordering.

Q: Do I need special tools to install wheel bearings?
A: Proper installation typically requires basic hand tools and the correct bearing driver or press tools to avoid damaging the hub or bearing seats. For best results, install bearings squarely, avoid force through rolling elements, and verify seal orientation during assembly.
