hehe, thats actually all you need, and a jack and wheelspanner of course
Easy to do yourself, and part number is LL4605A458, OEM or ATE689 / DDV 1021 or 1839 pirate parts, which I personally would not put in....
Mitsu East rand charges R900 incl supply.
Midas around R445, but I'd put in OEMs. They bed in quickly, fit properly, dont squeak and grind...
