Use copperease/copaslip. You can also buy a puller tool to remove
them, but if you copper-grease them before refitting you'll not need
it next time.

DO NOT USE COPPER SLIP. Use molyslip


*shrug* I've read the warnings that it worsens galvanic corrosion. I've
also recently removed the wipers on a 20 year old car which were a
******* to get off 15 years ago, but came off by hand after using copper
grease that time.
