What's wrong?
The rear suspension fasteners on 2020-2022 Spartan K1 and K2 RV chassis hold the rear-drive axle to the suspension. These torque box and lower torque rod fasteners are the clamping hardware that keeps the axle located under the motorhome as the suspension moves over bumps, turns, and braking loads. They have to be tightened to the right torque so the joint stays locked in place.
On affected chassis, Shyft says the torque and torque-verification process was not followed during final assembly and inspection. Fasteners that were not tightened properly can loosen or break in service. Once that joint loses clamp force, the rear-drive axle can shift rearward or to one side instead of staying square under the vehicle.
There is no warning sign before the rear axle shifts. An owner is not given a normal dashboard light, noise, or handling clue that proves the fasteners are about to loosen or break.
