How do you adjust the front wheel bearings on a ford e-350 van?

To adjust the front wheel bearings on a Ford E-350 Van, start by safely lifting the front end and removing the wheel. Then, remove the dust cap and cotter pin to access the adjusting nut. Tighten the adjusting nut to eliminate any play in the bearing, then back it off slightly to allow for a small amount of play, and secure it with a new cotter pin. Finally, reassemble the dust cap and wheel, ensuring everything is properly torqued.
