Try the least expensive method: Find a wooden dowel (or metal rod) that fits
very snug into the old pilot bearing, pack as much wheel-bearing grease as
you can into the pilot bearing, push in the dowel, then pound it in with a
hammer, and voila'- the hydraulic pressure will pop that bearing right out.
Please wear you safety glasses!
