My 2015 250 was eligible for permanent drive shaft fix. I drove from NY to Florida and had a vibration (fortunately at the end of the trip). Florida dealer had it done in about two hours. Discovered when driving at highway speeds over 65 mph there was a vibration that would come and go...
Has anyone installed windows that cut the ribbing between the mid and rear panels?
This is a mockup - I've outlined in blue the ribbing between the mid and rear factory window cutouts.
Is this going to jeopardize the integrity of the van, or lead to noise and vibration issues?
