I'm replacing the lower control and lower control arm rear (compression rod) but need help regarding the sleeve/seat. I ordered Nissan part #40173-33P00 for the compression rod. I researched this and found it on one of the G35 forums. My question is, can I use the same part # for the lower control arm ball joint that connects to the knuckle or is it a different size and part #? I know I can just remove it from the old ball joint but it's a pain in the *** and I almost broke the one I have. I'd rather just buy a new sleeve/seat. Any help would be appreciated.
