For the past 2 months I've been trying grade the front suspension I was trying to replace all the ball joints but for some reason the lower ball joints do not fit properly it would not let me insert the snap Ring I went through all the auto parts stores and all the ball joints that they had do not see all Way throughTo let me put the snap ring on

 

Has the lower control arm ever been replaced? You only solution may be to replaced the lower control arm assembly.
