Hello! I just got my CV shafts replaced on my 1998 Integra LS and the mechanic told me my lower left ball joint seems a little loose and should be replaced. I was looking for the part online to save some costs but got confused as to which part to buy. Does my car have front and back and upper and lower ball joints on each wheel? How many ball joints does my car have exactly? Also should I have them all replaced at the same time? Thanks in advance. Hoping to get this fixed in the next week or two.
