Hello All,
Just purchased a new motorhome with the E450 engine, currently 2300 miles, and noticed a knocking sound when turning in either direction. The knock only occurs when moving and turning.
Bushings, tie rods, cv joints all look good and tight.
Any ideas.
Thanks
John

 

Might be a typo, but there usually aren't any cv joints on those vehicles.
Best to have the dealer check it out. Sometimes the steering stops will make a noise when at the end of the turning angle against the stops.

 

You mean you have an E-450 chassis built motorhome. The E-450 chassis' come with either the 5.4L V8; 6.8L V10 2V; 6.8L V10 3V engines depending on how the dealer orders them for use and equipage build. The 6.8L V10 2V is the most common motor home chassis engine. The E-450 still uses the twin I-Beam suspension in them. Since it's under warranty, definitely have it looked at by the dealer as Hanky stated.
