Forum Thread: Bearing Stuck on Skateboard Trucks

It's been about 6 months since changing bearings on my board. 3 wheels came off normally 4th wheel I finally got free after destroying the bearings. After fighting the wheel for some time I'm left with the inner ring of the bearing seized onto the trucks. Tried WD40 and pliers. Any other ideas? P.s living in Honolulu lots of salty air and rain makes lots of rust.
