The correct bearing kit for a 2022 Forest River Riverstone Reserve 5th Wheel with Dexter 7,000 Lb Axles is the Bearing Kit, 14125A/ 25580 Bearings, 10-36 Seal part # BK3-200.

Based on the GVWR of your 2019 Jayco North Point 315RLTS it does seem like you have 7k axles. I recommend verifying this information to be sure. These axles typically use the #14125A outer and #25580 inner bearing found in the Timken #TMK92VR.…
