APPLICABILITY:

INTRODUCTION:

The purpose of this bulletin is to supplement the rear tie rod adjustment procedure in the Repair Manual to assure that the proper tightening sequence is followed. The following procedure should be used whenever performing a toe adjustment during a rear wheel alignment.





WARRANTY INFORMATION:





REQUIRED TOOLS & EQUIPMENT:





PRECAUTIONS FOR TORQUE WRENCH WITH EXTENSION TOOLS:

1. Torque wrench reading calculation.

A. If a torque wrench is used together with an SST or extra tools that extend the handle length, an actual torque will be greater than the set torque on a torque wrench.

B. This document specifies the required torques and the torque readings that will be set on general tools. If tools that are different from those described in this document will be used, calculate torque readings in accordance with the formula described in step (c) below.

C. Calculation formula: [Torque wrench reading] = [Specified torque] x L / (52 mm + L)

INSPECTION PROCEDURE:

When performing a rear wheel toe adjustment, carefully follow the instructions in this bulletin.





1. Inspect the rear No.1 suspension arm by inspecting the nuts and adjusting tube for looseness visually and by hand.





2. Put matchmarks onto the rear No.1 suspension arm assembly as shown in the illustration below.

3. Check adjusting tube for looseness.

Using the SST, try turning the adjusting tube in both clockwise and counterclockwise directions with the torque specified below to check that the match marks will not be misaligned.

WARNING

Do NOT apply more force than specified when checking for adjusting tube or jam nut looseness.

SST: 09617-24011





Torque:
Without SST: 20 N*m (204 kgf*cm, 15 ft*lbf)

Torque:
With SST: 17 N*m (173 kgf*cm, 13 ft*lbf)

Use a torque wrench with a fulcrum length of 300 mm (11.8 in.)

4. Check the lock nut at the ball joint side for looseness.

Holding the adjusting tube and using the SST, turn the lock nut at the ball joint side in both clockwise and counterclockwise directions with the specified torque to check that the matchmarks will not be misaligned.

WARNING

The wrench applied to the adjusting tube should NOT be turned during this step. HOLD the wrench applied to the adjusting tube while applying force to the SST or torque wrench.

If the lock nut is found loose replace the tie rod assembly.





Torque:
Without SST: 20 N*m (204 kgf*cm, 15 ft*lbf)

Torque:
With SST: 17 N*m (173 kgf*cm, 13 ft*lbf)

Use a torque wrench with a fulcrum length of 300 mm (11.8 in.)

ADJUSTMENT PROCEDURE:

1. Tighten the inboard (bushing side) lock nut.





Torque:
Without SST: 56 N*m (571 kgf*cm, 41 ft*lbf)

Torque:
With SST: 49 N*m (500 kgf*cm, 36 ft*lbf)

2. Tighten the outboard (ball joint side) lock nut.





Torque:
Without SST: 56 N*m (571 kgf*cm, 41 ft*lbf)

Torque:
With SST: 49 N*m (500 kgf*cm, 36 ft*lbf)

3. Tighten the inboard (bushing side) lock nut again.





Torque:
Without SST: 56 N*m (571 kgf*cm, 41 ft*lbf)

Torque:
With SST: 49 N*m (500 kgf*cm, 36 ft*lbf)
