The Mueller-Kueps Twin Cone Wheel Bearing Kit, No. 432 005, is designed to make all hub assemblies easy to remove. Use a slide hammer, attach the spindle, nut and cone that are needed and proceed like normal. The company recommends the Mueller-Kueps Slide Hammer, No. 433 450, for best results. The tool provides a solid connection to reduce accidents.This kit comes with two sets of three cones, one spindle and two nuts. The cones are self centering to achieve the most solid and universal connection. Made specifically for the new screwed and pressed hub assembly, it still works for most other wheel bearings as well.
