Results of the tests
0PRELIMINARY CHECKSAll OKProblems metOperation
Carry out a test, steering on full lock in various conditions to check whether the steering stiffens in both directionsVisually inspect the power assisted steering fluid level in the reservoir Continue to Step 1 Hardness in one direction only See table   H11 
Power assisted steering fluid level too lowRestore the correct level, if there are leaks, See table   X30 
1TYPE OF FAULT CHECKAll OKProblems metOperation
Carry out a test, steering completely in various conditions: check the method in which the fault arisesStiffness continuous and constant: Continue to Step 2 Hardness intermittentCheck that the filter inside the reservoir is correctly positioned. If necessary, replace the chamber Op.   4130B10  ;
Hardness only during idlingCheck for any restrictions in the system pipes, flexible and rigid.If necessary, replace the damaged parts, replacing all the seals (see Assembly 4130B)
Hardness in end of travel positionRestore the correct wheel geometry (see Assembly 4450A)
