Does anyone know what the load is to pull the steering arm on the hydraulic idler? The steering on my P6 is very heavy, and once the idler was removed it felt normal. On the bench it felt ok, some resistance but I don't have any reference to what load is required to move it round? Draining the oil and refilling with fresh 20w50/EP90 mix has lightened the steering, but it still feels heavy with the idler refitted. The steering box and all balljoints feel fine and turn ok as far as I'm concerned.
