A broken dip stick tube or bushing remover is provided including a bolt having a cylindrical configuration with a top, a smooth intermediate extent, and a threaded bottom. A puller is provided having an upper portion with a cylindrical configuration and a threaded bore formed in a top face thereof for removably coupling with the threaded bottom of the bolt. The puller further has a bottom portion formed of a cylindrical rod with a diameter less than that of the upper portion and terminating in an enlarged head. The entire bottom portion has a plurality of longitudinal slots formed therein thereby forming multiple spaced resilient members which are adapted to be biased radially inward. A locking pin is situated between the spaced resilient members along an axis of the puller. Next provided is a slide hammer having a coaxial bore formed therein for allowing the intermediate extent of the bolt to be slidably situated therein.
