Review on ACDelco 45K0150 Professional Caster Eccentrics by Jason Man

Great regulator! If you do this, be sure to replace one side of the control arm at a time. The nuts are torqued to 111 ft-lbs, which is the OEM setting. It also helps to clean the holes in the frame first before putting on the base part. It is best to use a 1 1/2" socket with 1/2" drive (flat blade) to adjust the front wheel - simply loosen the small nut slightly and then use the socket wrench to turn the large nut to adjust. Carefully adjust each side in equal amounts to change camber or your caster will adjust too.
