Ford E450

Hello All,
I recently purchased a 2016 Forester with the E450 engine. I have noticed that whenever I turn, either direction, I get a knocking sound. Driving straight on the interstate no problem.
Any ideas.

Hard to tell - maybe something is binding? I'd have it looked at. Our previous RV was on an E-450 chassis and we didn't have any issues with noises on turns.

Can you be a little more specific on the knock sound. Does it happen when you are driving away from a stop sign and making a slow turn left or right? Is it actually a knock sound or more like a bang or pop noise? Where does the noise seem to be coming from - front engine compartment, middle of the Motor home or at the rear axle?

I have an E450 that started making a bang noise when I made a slow left or right turn from a stop sign. Turned out to be the long metal heat deflector plate that runs in between the exhaust pipe and the floor. A couple of the screws holding it to the chassis came loose and was catching and binding on the chassis when turning due to flexing. I tightening them back up and the noise disappeared.

The sound is sort of knocking/creaking. Only happens when in drive. For example if I turn the wheel with my foot on the break I get the sound. If in park and turn the wheel no sound. Its coming from under the drivers compartment somewhere by the step in. I took it to ford and they couldn't find anything said everything appeared tight. They were going to call ford tech to discuss next steps. Scheduled to bring it back in on Monday.
I will let everyone know how it turns out. I hoping nothing to serious.

Are you heading this noise when not moving ?

If it happens when not moving with your foot on the brake, the brakes will creek due to 1 wheel rolling slightly foward and 1 back due to the steering geometry.

Any resolution to the problem? I am curious because I just took delivery of a 2016 FR Sunseeker with the E450 chassis, and haven't had a lot of driving time behind the wheel.

Hi everyone,
Issue resolved. The problem was the one of the bracket mounts for the driver side step was getting torqued every time the I turned the steering wheel creating knocking/creaking sound. The fix was just to insert rubber washers in the bracket bolt.

Thanks for everyone's input. I am thankful it was nothing serious.
