The upper ball joint hole in the spindle is about 12mm and the new ball joint is 1/2”.
Use a 1\2” drill bit to enlarge the hole. Do not change the taper only enlarge the
smallest part of the hole. Use two 1/2” flat washers between the castle nut and the
spindle on each side Install new arms with factory hardware and attach brake line with
zip tie. Grease all grease fittings.
According to the DJM instructions, I have to drill out the hole in the spindle. It says not to change the taper. By simply drilling this top hole with 1/2" drill bit, I'm not going to be changing the taper am I?:think: It says only enlarge the smallest part of the hole. Is this the top hole of the spindle (green) or the bottom of the UCA balljoint hole (red) that they're referring to?
