I have a 2000 'V' LS400 and I originally had a problem with the tilt action of the steering. This was purely down to the motor which I replaced.
Now the telescopic action is playing up. It seemed that it had got tight as the motor would try but couldn't move the steering. If I pushed or pulled on the steering wheel at the same time, it would move. I have just removed, stripped, and re-greased the steering column and sure enough it had pretty much seized up, but even after stripping, cleaning and regreasing, the telescopic action is still the same. I am wondering if the motor is failing and not producing enough torque for the job? Does anyone else have experience of this? Is the telescopic action always stiff as even after regreasing the sliding tube and splined shaft, it still takes some force to move it?
