those with aftermarket rear control arms

[ONEBADPNY]

i bought a set from d&d motorsport and they do not have a grease fitting on them. everytime it is cold outside they squeak. can i add them to the upper and lowers without taking them out of the car? i think the squeaking is from the bushing onto the frame/brakets on the car so maybe they would not help this.

did you you put any grease on the outer edges of the bushings when you slipped them in? I probably wouldn't worry about it much since polyurathane bushings are a bit noiser anyways. as far as putting grease zerks on the arm itself i would remove the bushings then drill and tap a whole an screw in a zerk. then reinsert the bushings. Not sure if the grease would squeeze out to lube the outer edge or not?
