Vehicles with 2.0L or diesel engines
The power steering system is a rack and pinion design, with an engine-driven pump providing the steering assistance.
Vehicles with 2.5L or 3.0L engines
The power steering system is a rack and pinion design, with an engine-driven pump providing the steering assistance. The system features variable steering assistance with vehicle speed and a variable ratio steering rack.
Absolute cleanliness must be observed when replenishing the fluid or dismantling any part of the system. New fluid from a sealed container must be used.
Note. If the steering gear, pump or cooler are being replaced for leakage or noise related issues and there is no evidence of fluid contamination, there is no need to replace the reservoir.
In some cases where the fluid clearly contains particulate matter, and the system continues to function, flush the system with fresh fluid and replace the reservoir, as there is the possibility that the reservoir internal filter may be damaged or faulty.
Torque Ripple
Torque ripple is a concern with Electric Power Steering (EPS) systems. Torque ripple is most evident at static-park steering the wheel very slowly from lock to lock. Torque ripple is primarily caused by motor commutation.
Torque/Velocity Variation (Phasing/Effort Cycling)
Steering wheel torque variation occurring twice in one revolution is normally as a result of problems with the lower steering column (intermediate shaft), but foul conditions generally result in either constant stiffness or single point stiffness. Depending upon the orientation of the joints, the steering can feel asymmetric (torque falling off in one direction and rising in the other) or else it can simply have pronounced peaks and troughs as the steering moves from lock to lock.
