Toe Pattern Measurement
WARNING: This page is about a different car, the 2006 Dodge Viper. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
Toe Pattern Preparation procedure must be performed before Toe Pattern Measurement.
- Raise vehicle by frame (near PLP holes, but allowing room for Suspension Height Gages, Special Tools 6914 and 8897, installation later). See Figure and Figure.
- Remove all four wheels.
- Disconnect front and rear stabilizer bar links from lower control arms. (Refer to SUSPENSION/FRONT/STABILIZER LINK - REMOVAL) and (Refer to SUSPENSION/REAR/STABILIZER LINK - REMOVAL)
- Remove front and rear coil-over-shock assemblies. (Refer to SUSPENSION/FRONT/SHOCK - REMOVAL) (Refer to SUSPENSION/REAR/SHOCK - REMOVAL)
- Install wheels.
- Install Suspension Height Gages, Special Tools 6914 and 8897, and lower vehicle to design height. (Refer to SUSPENSION/WHEEL ALIGNMENT - STANDARD PROCEDURE - DESIGN HEIGHT MEASUREMENT)
- With vehicle at design height, measure and record front and rear toe at each wheel.
- Raise front and rear of vehicle 25 mm (1 in.) above design height (Rebound). Measure and record front and rear toe at each wheel.
- Raise front and rear of vehicle 50 mm (2 in.) above design height (Rebound). Measure and record front and rear toe at each wheel.
- Return vehicle to design height.
- Lower front and rear of vehicle 25 mm (1 in.) below design height (Jounce). Measure and record front and rear toe at each wheel.
- Lower front and rear of vehicle 50 mm (2 in.) below design height (Jounce). Measure and record front and rear toe at each wheel.NOTE: It may not be possible to obtain a wheel toe reading with the vehicle lowered 50 mm (2 in.) below design. If not, measure at nearest attainable millimeter mark and record as such. It can be drawn in on Dynamic Toe Pattern Graph and used along with other plotted readings from other height settings to determine toe pattern arc.NOTE: Design Arc and Range guidelines (specifications) printed in Dynamic Toe Pattern Graph are for each individual wheel. Recorded measurements plotted on graph should also be drawn in per wheel.
- Plot toe readings for front suspension on Dynamic Toe Pattern Graph provided . See Fig 1. If toe pattern arc is within allotted range, front toe pattern is within limits. If toe pattern is not within allotted range, steering gear must be raised or lowered to achieve proper toe pattern.
- Plot toe readings for rear suspension on Dynamic Toe Pattern Graph provided . See Fig 1. If toe pattern arc is within allotted range, rear toe pattern is within limits. If toe pattern is not within allotted range, toe links must be raised or lowered to achieve proper toe pattern.
