The Snap-on Ball Joint Removers for Subaru Vehicles, Nos. BJR1 and BJR2, increase productivity and save technicians valuable time on the job with faster, safer ball joint removal, says the company. They easily remove stubborn ball joints that are heavily corroded. The puller screw threads onto the ball joint stem and the cup rests against the steering knuckle. The 3/4" hex on the puller screw can be driven by hand or with an impact gun to easily remove the ball joint. The industrial finish helps protect against corrosion. The BJR1 remover is designed for use on Subaru 2003-2006 Baja, 1998-2020 Forester, 1993-2020 Impreza, 1990-2020 Legacy and 2000-2020 Outback, 2016-2020 Crosstrek models. The BJR2 remover is designed for use on 2006-2014 Subaru Tribeca, 2018-2020 Ascent models.
