What owners report
Short excerpts of NHTSA complaints in the original wording. These are owner statements not verified by NHTSA; personal data removed.
Tl contact owns a 2001 western star 4964sx rv (na). The contact stated that the failure of the pusher axle (axle number 01-3-1-11) was causing the steering to deviate from the direction he attempted to steer. The dealer acknowledged the failure, but did not provide a remedy.
Brake hose chaffing against frame, routed incorrectly under sleeper causing rupture. Refer to diagrams shown with report.
The 5 air ride suspension valves would be at different heights all the time. Would "dump out" while going around curbs or corners or even at stops. The rubber ends on the rods were replaced with metal rods. They were not adjusted correctly. This caused vehicle to pull hard to the right. Would vibrate violently.
