cultus never come with grease able ball joints ,,,,,,,, usually older SUVs come with grease able ball joints ,,,,,,, but u can add them very easily ,,,,,, i did that on my nissan D21 center link ,,,,,,, all of its ball joints comes with grease nipples other then the one out of three ball joint of center link rod ,,,,,,,, just drill it ,, hand tap it and fit a grease nipple ,,,, also called Zerk fitting ,,,,, make sure no metal debris fell inside ball joint ,,,,,,you can find the grease nipple very easily from any tractor parts store ,,,,, because tractor suspension has plenty of grease nipples ,,,,,,,,
