What's wrong?
The spindle nut on a 2021 Carson Carrier trailer is the fastener that holds the wheel hub assembly onto the axle spindle. The hub is the part the wheel rides on, and the spindle is the fixed end of the axle that supports it. When the nut is tightened correctly, it keeps the hub centered and held with the right clamping force.
On affected Carrier trailers, the spindle nut was not tightened to the prescribed torque during assembly. That leaves the hub assembly held with less clamping force than designed. As the trailer is towed, extra movement at the hub can place abnormal load on the wheel-end parts and keep the axle assembly from working as intended.
There is no warning sign before failure. Do not rely on noise, vibration, or visible looseness to tell you the spindle nut is under-torqued.

What's the safety risk?
Improperly tightened spindle nuts can create excessive axle vibration and overheated bearings. That affects vehicle control and increases the risk of a crash. If the vehicle feels unstable or vibrates, slow down, stop in a safe place, and arrange dealer service. Repair is free at any franchised Carson dealer.
What should I do?

- Contact a franchised Carson dealer to schedule the free spindle-nut tightening that addresses axle vibration, bearing overheating, and vehicle-control risk.
- Bring the recall notice if Carson mailed one. If not, reference recall number 21V747 and Carson recall Recall3 when you call.
- Limit trailer use until the repair is complete; stop towing if you feel axle vibration, bearing heat, or control changes.
What happens at the repair
At the dealer, a Carson technician checks the axle spindle nuts on the 2021 Carrier trailer and tightens them to the proper specification. That work addresses spindle nuts that were not tightened correctly during assembly. The recall repair is free, with parts and labor covered by Carson. Ask the service desk to confirm that recall 21V747 applies to your trailer before the repair order is written.
