Rear Total Toe Specifications

NOTE: The Sienna rear suspension and axle beam assembly has a toe-correcting feature built in to the trailing arm bushings. (Refer to the Technical Information System [TIS], 2004 model year Sienna New Car Features, Suspension - Chassis and Drivetrain - "Suspension" .) For this reason, it is important to focus on the total toe measurement rather than individual right and left toe measurements. Most 4-wheel alignment equipment will measure and display individual right and left toe readings and may indicate that a right or left toe is out of specification. If total toe is within specification, you may disregard individual right and left readings as the rear suspension and axle beam assembly will automatically "correct" the individual toe settings while the vehicle is driven.
