What's wrong?
The rear drive axle on the 2021 Spartan K2 chassis is the heavy shaft and housing assembly that carries power to the rear wheels and supports suspension loads at the back of the motorhome. The rear suspension mounting bracket is welded to the top of that axle so the suspension can hold the axle in the correct position as the vehicle moves over the road.
On affected chassis, the bracket was not completely welded during axle production. Missing weld coverage leaves the bracket with less attachment than designed. Under normal suspension loading, the bracket can break free from the rear drive axle. That changes how the rear suspension is held and turns a hidden weld problem into a structural suspension failure.
The warning sign is a sharp "pop" from the rear of the motorhome if the mounting bracket breaks free. If you hear that sound from the rear suspension area, treat it as a sign that the bracket has failed.

What should I do?

What happens at the repair
At the dealer, a Spartan technician inspects the rear drive axle and the welded rear suspension mounting bracket area. If the inspection shows the axle needs replacement, the technician replaces the rear drive axle. The recall repair is free, with parts and labor covered. Shyft Group's standard reimbursement plan covers documented out-of-pocket costs for the same repair before the recall notice. Bring prior repair paperwork to the service desk so the dealer can explain the claim process.
