Disassembly and AssemblyST-23 Components:
ST-24 Components:
DISASSEMBLY
1. Remove spring from steering column assembly and tilt lever.
2. Remove upper joint bolt, then remove upper joint from steering column assembly.
3. Remove ignition switch tamper resistant self-shear type screws with a drill or other appropriate tool.
ASSEMBLY
^ Assembly is in the reverse order of disassembly.
^ Install new tamper resistant self-shear type screws.
INSPECTION AFTER ASSEMBLY
When the steering wheel does not turn smoothly, check the steering column as follows:
1. Check the column bearings for damage or unevenness. Lubricate with recommended multi-purpose grease. Replace the steering column as an assembly, if necessary.
2. Check the column tube for deformation or breakage. Replace the steering column as an assembly, if necessary.
3. If the vehicle has been involved in a collision, or if noise and rattles are heard during a turn, check the length (L) of the column. If out of specification, replace the steering column as an assembly.
Steering column length (L): 610 mm (24.02 in)
4. Check for proper lubrication, apply grease as necessary.
5. Check for wear around the seal edges, replace as necessary.
6. Check for corrosion or pitting around the seal sliding area.
7. Replace the seal and shaft in case of seal edge wear or damage.
8. After installing the steering column, check the tilt mechanism for proper operation.
Tilt mechanism range (Manual Tilt): 3° per notch at 5 steps
CAUTION:
^ Do not exert any load or impact in the axial direction immediately before or after column removal.
^ After installation, check for smooth steering wheel rotation, without any catches or noise.
^ Replace the column if it is depleted of grease, worn, damaged, or if any scratches or coating separation is present on the shaft seal area.
^ The lower nut on the upper joint may not be reused.
^ During lower joint detachment, insert a tool into the yoke groove to prevent gouging damage.
