Here's a great tool to get those stubborn stub axles and hubs out without removing your trailing arms.
The Baum Tools B234MASTER Hydraulic Axle Extractor and Slide Hammer Hub Remover Tool Kit is used to hydraulically push out stubborn axles using the included hydraulic ram, and the 22 lb slide hammer is used to remove wheel hubs.
B234MASTER includes both 4 and 5 lug hub adapters, and the hydraulic ram is intended to be used with a 10 Ton PortaPower hydraulic pump (pump not included).
