THIS WAS JUST TIME TO REPLACE THE RACK SUSPENSION CARTRIDGE. 267,485 MILES ON THE ORIGINAL HOW IT WAS OBTAINED. NOT A TASK FOR THE WEAK HEART BUT REMOVING THE SPRING SELECTS THE OLD CARTRIDGE AND CLEANS THE OIL. THIS ARTICLE IS PERFECT AS IT SHOULD BE. AFTER I DRIVE THE CAR I WAS SATISFIED WITH THE IMPROVED RIDE. FYI: GET MORE IN 200,000 MILES! HAPPY CAR.
