I have a 98 SH and am about to change the ball joints. My buddy drives a 4th generation and is about to do the same. The ball joints look identical when we ordered them. However the part number is different and whereas the 4th gen parts are approx 90 bux a pair, the 5th gen parts are 120 bux a piece! Crazy, are the parts different? Can i use the 4th gen?
(lower front ball joints)

Thanx a bunch
