Affects Kenworth T800, T600, T660, T2000, W900 · 2009 — about 34 vehicles.
The hazard
On certain trucks, the rear axle u-bolts may have received insufficient tightening torque during vehicle assembly. This could allow the u-bolts to loosen over time, which may cause vibration in the rear suspension. If multiple fasteners were to become loose, the U-bolt holding the axle may lose clamp load and the rear axle may shift relative to the rear suspension drive beam, which might result in a crash causing personal injury or death. Correction: Dealers will tighten the axle u-bolts.
