4. Remove lock nut and bolt, then separate upper shaft from upper joint.
5. Remove two nuts and two bolts, then remove steering column assembly from steering member.
6. Remove hole cover seal and clamp.
7. Remove nuts, then remove hole cover from dash panel.
8. Raise vehicle, then remove bolt (lower side) of lower joint shaft and remove lower joint shaft and upper shaft as an assembly.
INSPECTION AFTER REMOVAL
• Check for damage to steering column jacket tube. If damage is found, replace steering column with new
one.
• If vehicle has been in a collision, check column length (L), (L
1) and (L2) as shown. If out of specification,
replace steering column with new one.

STEERING COLUMN
1. Check the column bearings for damage or unevenness. Lubricate with recommended multi-purposegrease. Replace the steering column as an assembly, if necessary.
2. Check the column tube for deformation or breakage. R eplace the steering column as an assembly, if nec-
essary.
3. If the vehicle has been involved in a collision, or if noise and rat- tles are heard during a turn, check the length (L) of the column.
If out of specification, replace the steering column as an assem-
bly.
4. Check for proper lubrication, apply grease as necessary.
5. Check for wear around the seal edges, replace the steering col- umn as an assembly 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.
CAUTION:
• Do not exert any load in the axial direction immediately before or after column removal.
• After installation, check smooth steering wh eel rotation, without any catches or noise.
