2000 Ford E-Series Van Repair Question
Why does my 2000 E250 Van @highway speeds vibrate on deceleration?
Measure the ride height. Any tire and alignment shop will have a spec book that shows where to take the measurements and what they should be. Most likely they will recommend new rear springs or helper springs to make up for the weight if the lift. Ford has had a problem for many years with a vibration from incorrect drive shaft angle. It was worst on conversion vans due to the added weight and usually showed up when they were about six months old after the springs had settled a little.
