i recently removed the lower ball joints from my da's knuckles, i got my new ones from the dealership. and theres no groove in the new ones to catch that c-clip thats goes on the bottom side of of them (near the boot). the clip is supposed to be on there to keep the balljoint from coming out of the knuckles. has anyone ever replaced theirs and had a problem?

the balljoint part # i ordered is 51220-SK7-013.
