STEERING GEAR AND LINKAGE DISASSEMBLY
| CAUTION | To prevent damage to the steering gear, secure it to the vise using a copper plate or clean cloth. |
Scheme 21
- Disassemble in the order indicated in the figure. (Scheme 21): Identifying Steering Gear And Linkage Disassembly Order
Scheme 22
Scheme 22: Tie-rod End Disassembly Note
- Place alignment marks as shown in the figure for proper installation. (Scheme 22): Identifying Alignment Marks On Tie-Rod End
- Remove the tie-rod end.
Scheme 23
Scheme 23: Boot Clamp Disassembly Note
- Insert a flathead screwdriver into the boot clamp as shown in the figure, then press the caulked area outward to remove the boot clamp. (Scheme 23): Inserting Flathead Screwdriver Into Boot Clamp
Tie Rod Disassembly Note
| CAUTION | If the steering rack is secured to a vise without using a cloth, the sliding surface of the steering rack could be damaged. Always use a clean cloth when securing the steering rack to the vise. If the steering rack is secured to a vise in the incorrect position, the steering gear could fall off the vise and be damaged during the operation. Always secure the steering rack to the vise in the proper position. If the tie rod joint does not have a tool installation surface (34 mm {1.3 in} across flat), the tightening torque during installation cannot be measured. Therefore, disassemble the tie rod joint only when replacing it. |
Note. A new tie rod includes a tool installation surface ( 34 mm {1.3 in } across flat).

Scheme 26
Scheme 27
- Protect the steering rack tooth surface using a clean cloth and secure it using a vise. (Scheme 24): Locating Steering Rack Tooth Surface Vise Fixing Position
- Perform the following procedure according to whether or not the tie rod has a tool installation surface ( 34 mm {1.3 in} across flat). (Scheme 25): Identifying Tie Rod With Tool Installation Surface (34 mm {1.3 in} Across Flat) (Scheme 26): Identifying Tie Rod Without Tool Installation Surface (34 mm {1.3 in} Across Flat) Tie rod has tool installation surface ( 34 mm {1.3 in} across flat) (Scheme 27): Identifying Tie Rod Tool Installation Surface (34 mm {1.3 in} Across Flat) Disconnect the tie rod using the SST.
Scheme 28
- Tie rod does not have tool installation surface ( 34 mm {1.3 in} across flat) (Scheme 28): Disconnecting Tie Rod Using Pipe Wrench Disconnect the tie rod using a pipe wrench.
Scheme 29
Scheme 29: TIE-ROD END INSPECTION
- Inspect the tie-rod end for damage and the boot for cracks. If there is any malfunction, replace the tie-rod end.
- Inspect for excessive play. If there is any malfunction, replace the tie-rod end.
- Rotate the tie-rod end five times.
- Measure the rotational torque of the tie-rod end using the SST and a pull scale. (Scheme 29): Measuring Rotational Torque Of Tie-Rod End Using SST And Pull Scale If not within the specification, replace the tie-rod end. Tie-rod end rotational torque 0.5-3.0 N.m {5.1-30 kgf.cm, 4.5-26 in.lbf} [Pull scale reading: 5.0-30.0 N {0.6-3.0 kgf, 1.2-6.7 lbf}]
Scheme 30
Scheme 30: TIE ROD INSPECTION
- Inspect for bending and damage. If there is any malfunction, replace the tie rod.
- Inspect for excessive play. If there is any malfunction, replace the tie rod.
- Swing the tie rod five times.
- Measure the swing torque of the tie rod using a pull scale. (Scheme 30): Measuring Swing Torque Of Tie Rod Using Pull Scale If not within the specification, replace the tie rod. Tie rod swing torque 0.5-3.0 N.m {5.1-30 kgf.cm, 4.5-26 in.lbf} [Pull scale reading: 10-60 N {1.1-6.1 kgf, 2.3-13.0 lbf}]
STEERING GEAR AND LINKAGE ASSEMBLY
| CAUTION | To prevent damage to the steering gear, secure it to the vise using a copper plate or clean cloth. |
Scheme 31
- Assemble in the order shown in the figure. (Scheme 31): Steering Gear And Linkage Components With Torque Specifications
Tie Rod Assembly Note
| CAUTION | If the steering rack is secured to a vice without using a cloth, the sliding surface of the steering rack could be damaged. Always use a clean cloth when securing the steering rack to a vise. If the steering rack is secured to a vise in the incorrect position, the steering gear could fall off the vise and be damaged during the operation. Always secure the steering rack to the vise in the proper position. |
Scheme 32
Scheme 33
Scheme 34
- Protect the steering rack tooth surface using a clean cloth and secure it using a vise. (Scheme 32): Locating Steering Rack Tooth Surface Vise Fixing Position
- Combine the SST with the torque wrench, then measure A and L as shown in the figure. (Scheme 33): Measuring A And L With SST And Torque Wrench A: Length from the center of the tie-rod to the grip. L: Length of the torque wrench.
- Recalculate the torque by using torque formulas, then tighten the tie rod using the SST. (Scheme 34): Tightening Tie Rod Using SST CAUTION: When installing a torque wrench to the SST (49 E032 308), install it perpendicular to the SST as shown in the figure. If installed incorrectly, the SST could separate from the tie rod, which could cause damage to the tie rod. Tightening Torque 70-95 N.m {7.2-9.6 kgf.m, 52-70 ft.lbf}
