JAVIK Ball Joint Kit for Yamaha ATVs — 4-Piece Upper & Lower Set (OEM 37S-23549-01-00) with Hardware

JAVIK's Ball Joint Kit is a complete upper and lower replacement set (OEM# 37S-23549-01-00) that includes four ball joints and all mounting hardware for compatible Yamaha ATV/UTV models.

If your Yamaha ATV or UTV shows looseness in the front suspension, uneven tire wear, or imprecise steering, replacing worn ball joints can restore control and handling. This kit supplies four ball joints plus lock nuts, split pins, and circlips so you can service both sides without hunting for extra parts. Components are made from iron with rubber seals to resist contaminants, and the package maps directly to a wide range of Yamaha models across the Rhino, Grizzly, Kodiak, Wolverine, Big Bear, and Bruin lineups.

Which Yamaha models will these ball joints fit?

This kit fits many Yamaha ATVs and side-by-sides when the OEM number 37S-23549-01-00 is required. Check your vehicle year and model against the fit list before ordering to ensure correct compatibility.

What comes in the package and how does it simplify installation?

The kit is delivered ready for a full front-end service: four ball joints with the fasteners required to install them. Having all four joints and matching hardware saves time and avoids multiple trips to suppliers, letting you complete a symmetrical suspension refresh in one session.

• 4 ball joints (upper and lower positions covered)
• 4 lock nuts for secure torque retention
• 4 split pins for locking castellated nuts
• 4 circlips to retain components as needed

What materials and build details should I expect?

These replacement joints use iron bodies for strength and molded rubber seals to help keep dirt and water away from internal surfaces. The design mirrors OEM fit and geometry so alignment and steering feel remain consistent when installed correctly.

• Iron construction for load resistance
• Rubber seals for contaminant protection
• Manufactured to match OEM# 37S-23549-01-00 fitment
• Supplied with matching fasteners for an OEM-style install

How should I maintain the replacement ball joints for long life?

After installation, inspect the joints periodically for torn seals or excessive play. Avoid direct high-pressure washing of joint boots and address any unusual steering noise or looseness immediately to prevent further suspension damage.

• Visually check seals for splits every few months
• Grease or lubricate only if the joint design allows or per service manual
• Replace both sides together to maintain balance and handling
• Keep wheel alignment and suspension geometry checked after replacement
