I HAVE BEEN USING CENTRAMATICS ON BOTH STEER AND DRIVE (SUPER SINGLES) FOR YEARS. I NORMALLY GET 200,000 PLUS OUT OF STEERS AND 450-500,000 OUT OF MY DRIVES. WOULD NOT HAVE IT ANY OTHER WAY. SMALL INVESTMENT FOR SUCH A LARGE RETURN.
And a full 3 axle alignment is an investment in tire life and handling, as well as extended drivetrain life. With the extended miles between oil changes, it does not hurt to do a lube job midway between full services.
