If grease is to thin we have used a bar of soap and cut it up.There are pullers out there but they typically have difficulty with brass or bronze bushings.
You can fill the inside cavity and whatever deep well socket just barely fits in it with grease. Then cover the whole thing with a rag and hit the socket with a BFH. Do it with conviction!!:yes::devil: You will "Hydraulic" the bushing out!!
The real trick is to make sure there is NO air behind the bushing or in the socket to compress.
I've actually found the "Hydraulic" method to be faster than using any of the fancy pullers especially since the pullers have a tendency to destroy the bearing and take multiple attempts. :yes:
