is a press required for the wheel berrings?
proceedure to change tie rod ends and wheel berrings on 1996 Ford Aerostar
Fronts are standard tapered roller bearings where you pack with new grease, so no press needed there. Rears are installed into the axle housing, so no press needed there either. If this Aerostar is all wheel drive, then you may need a press or bearing tool to do those front bearings.
