The Toyota Sienna minivan is based on the Camry platform and is available in 2WD and AWD versions. In 2011, Toyota introduced the third generation Sienna which stayed true to the base suspension setup of the previous generation.

There are three things you should know when aligning this vehicle. First, a Sienna with stability control will require recalibration of the steering angle sensor. Second, rear tire wear can be an issue on certain all-wheel-drive Sienna. Third, measure the ride height before trying to correct a front caster problem.

Front suspension

The Sienna’s front suspension is a MacPherson strut design. There is no adjustment of the casters. For 2011 models, Toyota provides information on different camber bolts with varying camber values ​​depending on the location of the points on the bolt head. But, it is better to use aftermarket cam bolts in the strut mounting holes. Some kits may give ± 1.75 ° of camber.

Keep an eye out for cross caster and camber tolerances as a significant difference between the two sides could cause a traction condition.

When inspecting the Sienna’s front suspension, watch out for the stabilizer bar links – these can wear out at the end like on a Camry. In addition, the ring on the back of the control arm may wear out. Tearing or separation of the rubber from the backing is one reason for replacement.

Rear suspension

The Sienna uses a swingarm rear axle on 2WD and AWD models. No adjustment is integrated into the axle. Replacement shims can be installed between the axle and the bearing flange to adjust toe and camber. These shims can adjust camber or toe-in by ± 1.00º.

The most common problem reported by drivers is wear on the inside edges of the rear tires. The main culprit is the lack of rotation. In some cases, this is an axle alignment problem. In addition, body heights and overloading can cause edge wear. But proper rotation can increase tire life.

There has been a recall on these vehicles for the spare tire carrier with 1998-2010 2WD models. The cable used to raise and lower the spare tire could corrode and break, so make sure the spare tire is secure. The differential for AWD models has taken up space for the spare part. This is why Toyota has made runflat tires standard on AWD models.

Zero point calibration

Newer van models (2004 – current) require a scan tool and a special procedure to perform a zero point calibration of the steering angle, yaw, and deceleration sensors. It is highly recommended to do this through the OBDII port. You can disconnect the negative battery cable, but this cannot confirm that the system has been calibrated. It is common practice to perform the battery disconnect procedure only for the vehicle to return with the VSC light on.

Using a scan tool is the best way to perform the VSC zero point calibration. You can reset the system by inserting two pins into the diagnostic connector and / or disconnecting the battery, but there is no way to confirm or document that the calibration has been performed.

The main function of the steering position sensor is to monitor the driver’s steering inputs. This includes the angle of the steering wheel and / or the speed at which the driver turns the steering wheel. The steering position sensor on the Sienna is located behind the steering wheel and is a high resolution sensor.

The VSC system relies on precise steering input from the steering angle sensor to analyze a situation and take appropriate action to help steer the vehicle on the intended course.

The Toyota VSC system uses information from the steering position sensor and compares the information to the yaw and deceleration sensor to determine what the car is doing.

After recalibration, the vehicle should be driven for five minutes and at least one lock-to-lock turn should be made.
