A funny thing happened at the truck shop yesterday while I was there picking up my 3011 after having an alignment completed. As part of their process they drive the vehicle on the highway before and after. I asked the manager who conducted the drive how it performed before and after. He said there was some improvement after but did I notice the vibration?
I was not really expecting that question but my answer was no. He went on to say that as part of their drive test they will typically run the RV's up to 75 since that seems to be the top speed limit in some states. Since we have had the vehicle I think the highest I have had it up too was a shade over 65 and when towing the car I'm typically doing 60. He also stated that the vibration he felt was probably due to a drive shaft balancing issue and even if I don't notice it at the speed I drive that over time even a slight imbalance in the drive train can prematurely wear out some of the components.
I went on to explain to him the drive shaft balancing issues the 2016 models have had (discussed in much detail here; 2016 E-450 Vibration issue
) after which he said I probably should check back with the RV manufacturer to have them look at it again as it might not have been properly resolved, at least on my vehicle.
So my question to the forum is? Has anyone with a 2016 model run it up to a higher speed and noticed any vibration? And, does everyone think that 2016 drive shaft vibration issue was actually corrected?
I might be able to give it a test myself tomorrow but for now I tend to believe the guy who does alignments and drive balancing for the last 20+ years that my rig may have an issue.
