The rear suspension mounting fasteners that attach the rear-drive axle to the rear suspension may not have been tightened properly, which could allow the fasteners to loosen or break.
Loose or broken suspension fasteners can allow the rear-drive axle to shift out of place, increasing the risk of a crash.
What to do
Shyft Group will inspect the rear suspension fasteners for damage, and replace and tighten them -- as necessary -- free of charge.
Owners may contact Shyft Group's customer service at (800) 582-3454. Shyft Group's number for this recall is 21-22.
