STEERING COLUMN
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. 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 column 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.
